Intercom Function
The TY91/TY92 radio has a built in intercom which can be installed as
permanently engaged or selected via a switch. The intercom is voice activated
and the audio is routed through to both of the headsets. The intercom squelch
and volume can be adjusted independently from the radio function through
the configuration menu.
Stuck Mic
If the PTT switch is stuck in the ON or transmit position, the radio will
automatically cut out after 35 seconds as a safety measure.
Configuration Mode
Additional setup items can be accessed by holding down the MON button for
5 seconds. The menu options can be selected using the larger inside tuning
knob and the parameter value can be altered using the smaller outside tuning
knob.
