7.2.5. n-5035 Voice Recorder
To turn on the voice recorder and perform recording proceed as follows:
(1) Set the voice recorder control panel switch to ON (BKn) with the INT
(CnY-7) circuit breaker closed. The recorder control panel is located on
the left side panel of electric overhead panel.
(2) On the voice recorder control panel set the AUTOSTART - CONT OP
(continuous operation) (ABTOnYCK - HEnPEPblBHMl PA50TA) selec-
tor switch to CONT OP (HEnPEPbIBHArl PA50TA) and the ICS-MIKE
(Cm-nAP) selector switch to ICS (CnY). The RECORD (3AnVlCb) and
BRT (nOACBET) indication lights on the voice recorder control panel
should come on to indicate that the recorder operates. The operation
mode is to be selected depending on time in flight. The CONTINUOUS
OPERATION mode is more preferable, because it ensures recording
without any separate sound loss, which happens while starting the re-
corder in AUTOSTART mode. If the time in flight does not exceed 4
hours the CONTINUOUS OPERATION and auto reverse are to be se-
lected for the recorder. If the time in flight is from 4 up to 9 hours auto re-
verse off mode may be selected providing that the rewinding mechanism
will be set in the initial position. The ICS-MIKE selector switch is to be set
toa position, which corresponds to the input from which the recording will
be performed. The recording from MIKE input is used if a need is to re-
cord an information, which is not intended for broadcasting. In this case
the operator has no access to interphone path, but he has a possibility to
listen with a lower volume to the information from interphone output of
the other radio communication means (call signal). The recorder opera-
tion is monitored with the RECORD light and by self-listening. If the tape
transport mechanism operates the RECORD light is illuminated. The re-
corder being supplied with power the red lighting of control panel illumi-
nates. The dimming control of the red lighting is performed with BRT po-
tentiometer.
The MIKE (nAP) mode is used when a need in covert recording of in-
formation not intended for broadcasting arises. In this case the pilot has
no possibility to go on the air for a radio contact.
(3) Set the AUTOSTART - CONT OP(ABTOnYCK - HEnPEPblBHArl
PA50TA) selector SWitch to AUTOSTART (ABTOnYCK). This done, the
tape transport should stop and the RECORD (3AnVlCb) light should go
out.
When the first work is pronounced into the interphone microphone or
through any radio station the RECORD (3AnVlCb) light should come on
to indicate operation of the tape transport in the AUTOSTART
(ABTOnYCK) mode.
At a lapse of 5 to 25 s after the end of voice message the tape transport
should stop and the RECORD (3AnVlCb) light should go out.
(4) Beside the manual energization of the voice reCOrder by means of the
switch on its control panel, the power is supplied to the voice recorder
automatically after the LG wheels come clear of the ground.
