January 15, 2004 747-400 Flight Attendant Manual Communications - Cabin Interphone Copyright © The Boeing Company. See title page for details. 4.20.4 D6-30151-TBC (pax) Cabin Interphone Calls Cabin interphone calls are initiated by removing the handset from the handset cradle (dial tone is heard) and dialing the two-digit code for the desired location or type of call. The calling station hears a ring signal until the handset is picked up. If the called station is already in use, the caller receives a normal busy signal. If the caller has dialed a non-existent two-digit code, or is dropped from a call already in progress, the caller receives a rapid busy signal. When an attendant station receives a call, the passenger address system (PAS) sounds a chime, and the pink station cabin interphone crew call light illuminates. Interphone calls are prioritized in the following order: Pilot Alert, Priority Pilot and Priority Cabin, All Call, Attendant All Call, and Station-to-Station calls. Call Types Pilot Alert Pilot Alert is used to notify the flight crew about an emergency. The Pilot Alert call is not inhibited at any time. The dial code for PILOT ALERT, PP, on the handset: • annunciates the call on the flight deck by sounding a single HI/LO chime. Note: Pilot alert calls take priority over all other calls to the flight deck. A lower priority call in progress is automatically disconnected. If more than one pilot alert call is initiated, all applicable callers are connected via a party line. Priority Pilot Priority Pilot is a private line between one designated cabin station (primary) and the flight deck. This is accomplished by either station dialing the PRIORITY PILOT code 33. The primary cabin station is normally at Door 1L. Any other station trying to dial code 33 will receive a rapid busy signal (connection not available). Priority Cabin Call Priority Cabin is a private line between two designated cabin stations (primary and secondary). This is accomplished by either station dialing the PRIORITY CABIN dial code 32. The secondary cabin station is normally at Door 4L. The primary station, normally at Door 1L, can call the flight deck or secondary station. The flight deck and secondary station cannot call each other. All three stations can be on the priority line at the same time, when the calls are initiated from the primary station. Any other station trying to dial either code 32 will receive a rapid busy signal (connection not available).

D6-30151-TBC (pax) 4.20.5 Pilot A normal two way call to the flight deck may be made by any station. Dialing the PILOT two digit code, 31: • annunciates the call on the flight deck by sounding 2 HI/LO chimes. All Call The All Call selection includes the flight deck and all designated flight attendant stations. Dialing 55, the two digit code for ALL CALL: • annunciates the call by three HI/LO chimes and a flashing cabin crew call light • connects each handset to the call as the handset is removed from the cradle. Attendant All Call Dialing the two digit code for attendant all call (ATT ALL CALL), 54, functions the same as an ALL CALL but does not include the flight deck. ATT ALL CALL calls: • are annunciated by a single HI/LO chime and a flashing cabin crew call light • connects each handset to the call as it is removed from the handset cradle. Cabin Ready Cabin Ready is used to notify the flight crew that the cabin is secured and ready for taxi. Dialing CABIN READY, 6P, on the handset: • sounds a single HI/LO chime on the flight deck • caller hears a rapid beep, beep and then a dial tone. Station-to-Station Calls Station-to-station calls are normal, non-priority/routing, two way calls between stations; for example, attendant-to-pilot, pilot-to-attendant, or attendant to attendant. Any station can make a call to any other station using the two digit dial code. Station-to-station calls: • are annunciated by a single HI/LO chime and a steady master call light. Once a station-to-station call is made, one or two more stations may be added to the connection. Party Line Calls The cabin interphone system has four party lines. Four stations can participate in a party line call. January 15, 2004 747-400 Flight Attendant Manual Communications - Cabin Interphone Copyright © The Boeing Company. See title page for details. 4.20.6 D6-30151-TBC (pax) Cabin Interphone Calls Normal Interphone Calls To place a cabin interphone call: • remove handset from the cradle (listen for dial tone) • enter the two digit code for the desired station. When the call is completed: • return the handset to cradle. Party Line Calls To place a party line interphone call: • remove handset from the cradle (listen for dial tone) • enter the two digit code for the first desired station • when the other station has answered, the caller then dials the two-digit code for the next (third) station to be added • ring will sound five times. If the called station has not answered by the fifth ring, the cabin interphone system will automatically cancel the call to the third station (stations one and two will still be on the line). • if a fourth station is desired, follow the same procedure as calling the third station. When the call is completed: • return the handset to cradle. Call Transfer When on a station-to-station call, to transfer the call to another station, dial the two-digit code for the desired station. When that station answers, replace the handset in the handset cradle or press the “R” (reset) key on the handset. Remote Answer Calls made to one station may be answered at a different station. To accomplish this, dial the two-digit code for the called station. This resets the other handset location to receive new calls.

Entertainment audio and boarding music can also be sent through the PA system. Flight attendants can make PA announcements using the cabin interphone handsets. Those announcements can be sent through the cabin interphone system or directly to all cabin areas using the Direct Access switch located on the interphone handset cradle. The handset cradles located at doors 1L, 2L, and 4L have Direct Access switches. Passenger address announcements are made by selecting the desired area on the handset and pushing the Push-to-Talk (PTT) switch on the handset. Direct access announcements are initiated by pushing the PA direct access switch on the handset cradle. Passenger Address Priorities Passenger address announcements are prioritized in the following order: • flight deck • direct access • priority announcements • normal announcements • pre-recorded announcements • video system audio • boarding music A higher priority announcement overrides a lower priority announcement. When the cabin interphone system is used to make PA announcements and a higher priority announcement is initiated, the cabin interphone system resets and a dial tone is heard in the handset. There is a flight deck indication when the PA system is in use in the passenger cabin.

Lavatory Waste System Waste water from the lavatory sinks is drained overboard through drain masts on the fuselage. Toilet waste is flushed into four waste holding tanks located in the bulk cargo area. The toilet waste is flushed into four waste holding tanks located below the main deck cabin, in the bulk cargo area. The two forward tanks have a capacity of 85 gallons (320 liters) each, for a total of 170 gallons (640 liters), and the two aft tanks have a capacity of 65 gallons (246 liters) each, for a total of 130 gallons (492 liters). The waste system uses a vacuum to collect the waste material and deposit it in the tanks. At altitudes above approximately 16,000 feet, the pressure difference between the cabin altitude and flight altitude moves the waste from the toilets to the tanks. Below 16,000 feet and on the ground, pushing the flush button on the toilet activates a vacuum system and the flush cycle. The flush cycle uses water from the potable water system, and lasts approximately six seconds. Once the flush handle is pushed, there is an automatic 15-second delay for a system reset before the next flush cycle can be initiated. This delay conserves water by preventing consecutive flushes if the flush handle is repeatedly pushed. Each tank system operates independently. The Waste Quantity Select switch on the Lavatory Operation/Waste Quantity Module, at the Door 2R attendant panel, can be used to check the waste quantity level of each tank. If a tank becomes full, the toilet flush system for that tank shuts down automatically. The flush system also shuts down automatically during ground servicing of the tanks. Lights on the Lavatory Operation/Waste Quantity Module illuminate to indicate flush system shutdown. Note: Toilet blockages can occur if large objects are flushed down the toilet. Items which commonly cause blockages are diapers, hand towels, cups, and large quantities of toilet paper.

D6-30151-TBC (pax) 5.10.11 Lavatory Smoke Detector Operation When smoke is detected in a lavatory, the amber Lavatory Call indicator light/Reset switch, mounted on the exterior wall above the lavatory door, flashes and a chime sounds in the cabin near the associated lavatory. The lavatory call light at the associated lavatory flashes. The system can be reset by pushing the Lavatory Call indicator light/Reset switch. When the Lavatory Call indicator/reset switch is pushed: • the lavatory master call light extinguishes • the continuous chime is turned off • the smoke detector horn silences • the Lavatory Call indicator/reset switch extinguishes • a smoke alarm suppression cycle is initiated in the smoke detector Note: If there is still smoke in the lavatory, the red Alarm Indicator Light on the smoke detector remains illuminated. • a lavatory smoke alert message is displayed on the flight deck When the smoke clears, the red Alarm Indicator Light extinguishes, the suppression cycle ends, and the smoke detector is sensitive to smoke again. Continue to monitor the lavatory until the red Alarm Indicator Light extinguishes. Note: When the smoke detector has been activated by smoke, lingering smoke in the detector sensor may cause reactivation. Blowing air into the detector sensor (the small screen cutout on the side of the cube extending from the unit) may clear lingering smoke.

Lavatory Fire Extinguishing System An automatic fire extinguishing system is located beneath the sink in each lavatory. A fire extinguisher discharges a halon vapor through either one or both of the heat-activated nozzles. Both nozzles discharge toward the waste disposal container. The color of the nozzle tips change to an aluminum color if the extinguisher has discharged. Lavatory Temperature Indicator A temperature indicator is located inside the waste compartment below each sink, behind and above the waste container. Grey dots on the indicator turn black when exposed to high temperatures. If any dot has turned black or a nozzle tip has changed color, the extinguisher has discharged.

D6-30151-TBC (pax) 5.20.1 5.20 Lavatories-Non-Normal Operations Lavatory Non-Normals Inoperative Toilet(s) If one of the toilets does not flush, use the the Lavatory Operation/Waste Quantity Module to check the status of the waste tank for that lavatory. If the waste tank is full, placard all lavatories connected to the full waste tank as inoperative. If the waste tank is not full, the affected lavatory should be placarded inoperative. If one or more of the toilets do not flush, check the placard on the Lavatory Operation/Waste Quantity Module at door 2R. Locate the LAVS INOP switch applicable for the inoperative toilet(s). If the light in the LAVS INOP switch is illuminated, the waste tank is full and the affected lavatories should be placarded as inoperative. If the LAVS INOP switch light is not illuminated, push and hold the LAVS INOP switch (may require holding switch for up to 30 seconds) until the LAVS INOP switch light illuminates. The vacuum flush system is now reset. If the toilet(s) still do not flush, the affected lavatory should be placarded as inoperative.

Waste Tanks Improperly Serviced Verification of waste tank servicing is accomplished prior to dispatch by viewing the Waste Quantity on Lavatory Operation/Waste Quantity Module. Rotate the Waste Quantity select switch through all four waste tank positions (FWD L, AFT L, FWD R, AFT R). The waste tank quantity level should be in the first half (from "E" to halfway) of the green color bar for an unused waste tank. A waste quantity indication in the yellow or red color band indicates an improperly serviced waste tank. Maintenance should be contacted to service any tanks not showing the proper indication.
