A. PA level adjustment

PA Level Adjustment Example ** ON A/C NOT FOR ALL

(1) On the PTP 110RH push the DSPL ON pushbutton switch.

the CIDS menu page comes on.

(2) Push the <PROGRAMMING related membrane switch.

the PROGRAMMING menu page comes on.

(3) Push the <CABIN PROGRAMMING related membrane switch.

the ENTER ACCESS CODE page comes on.

(4) Enter the access code 333 123 to the scratchpad field and push the <ENTER related membrane switch.

the next page with the <PA LEVEL ADJ message comes on.

(5) Push the <PA LEVEL ADJ related membrane switch.

the PA LEVEL ADJ page comes on.

(6) push the <CABIN IN DETAIL related membrane switch.

the CABIN SEG page comes on.

NOTE: The cabin segments are not equivalent to the cabin zones. The locations of the cabin segments are shown in the CFDS PA LEVEL REPORT (Ref. AMM TASK 23-73-00-860-005).

(7) Push the related SEG membrane switch to select the cabin segment.

the respective segment value flashes.
the <+ (DB) and <- (DB) prompts appear.

(8) Push the + or - related membrane switches to change the PA level value.

NOTE: The values are adjustable in 2 dB steps. The respective PA level in the cabin is updated immediately.

(9) Select the next cabin segment for updating or push the CONT> related membrane switch to get access to the ATTND page.
(10) After the update of all PA levels push the <RET related membrane switch to save the new PA levels.

NOTE: If a reset to the default PA level is necessary, select the related cabin segment or attendant station and push the <RES related membrane switch. Pushing the <RES related membrane switch, without selection of a cabin segment or an attendant station, resets all to the default values.

(11) For an update of the auto increase of the PA level select the <AUTO INCREASE membrane switch on the PA LEVEL ADJ page. The procedure is the same as for the cabin segment and attendant station PA level adjustment.
