Monitor Mode (12)
If the TY91 is interfaced as a standalone COM or as COM 1, the radio’s
standby frequency monitor can be used. To activate the monitor mode, press
and hold the
N1
button until “
MON
” appears in the display.
While receiving a signal on the active frequency
- the standby channel is
NOT
monitored.
While receiving a signal on the standby frequency
- the active channel is
periodically monitored. If a signal is found on the active frequency the
TY91
will revert to the active frequency. After a signal has been received, the
TY91L
will return to monitoring both frequencies.
It will be important to remember which station is active and which is
standby, to avoid answering a transmission on the standby frequency by
transmitting a response on the active frequency. You may notice a slight
“ticking” in the audio as the frequencies are being scanned in Monitor Mode.
If the active and standby frequencies are transferred, the Monitor mode is
canceled.
ICS and Radio Volume Controls (1)
Push the top line-select to
enter the volume mode
(
Vol

knob (ICS) controls the
volume of the intercom
audio. It does not affect the radio, telephone, or mu-
sic volume.
The outer knob (RADIO) controls the volume of the
Trig TY91 COM transceiver.
Cockpit Speaker (10)
When the cockpit speaker is
turned on, any receiver audio
selected will be heard in the
speaker. Any unswitched audio
will always be present in the
cockpit speaker.
