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 no-
tice 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.
Cockpit Speaker
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.
To activate the cockpit speaker, push and hold the N2 for about 1 second or
until the display shows SPR. Repeat to turn the speaker off.
Radio Sidetone & Radio Squelch Adjustment
To change the automatic squelch thresh-
old and sidetone level for the Trig TY91
transceiver: Enter the Radio Volume
mode by pressing the ICS button until
the setup screen appears
Turn the rights side outer knob to set the
squelch threshold to low (weak signals
open), medium (normal operation) or
high (blocks RF noise, requires stronger signals to open).
Turn the right side smaller inner knob to increase or decrease the radio side-
tone. Typically, the radio sidetone is adjusted slightly lower volume than he
received radio signals.
Intercom Operation (8)
IntelliVox® VOX-Squelch
No manual adjustment of the IntelliVox® squelch control is possible.
Through individual signal processors, the ambient noise appearing in all four
microphones is constantly being sampled. Non-voice signals are blocked.
