Rotating the small frequency selector knob will step through the
memory locations. The standby frequency window will display the
stored frequency.
To store a frequency in one of the memory locations it must first be
tuned and active as the primary frequency. Press MEM to enter the
memory mode in the usual way. Select the channel you want to
overwrite with the tuning knobs. Now press, AND HOLD, the MEM
button for 2 seconds. The current active frequency will be moved to
the selected memory location, overwriting the existing contents.
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.
