Figure 3-7 Monitor indication
When MON is active, the receiver is tuned to the Standby frequency and passes received audio on that
channel. When the Active frequency receives a signal, the signal from the active frequency is automatically
provided to the audio.
Both active and standby frequencies are monitored at the same time for a signal. A signal can be received
on either the active or the standby frequency.
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 re-
ceived, the TY91 will return to monitoring both frequencies.
The standby monitoring frequency sends an audible “ticking” to make you aware which is the active &
standby. It will be important to remember which frequency is active and which is standby, to avoid answer-
ing a transmission on the standby frequency by transmitting a response on the active frequency.
3.7.4 Tuning 8.33 kHz channel Spacing
Hold the “MUTE” button on the left side for 3 seconds, which will toggle between either 25 kHz spacing or
8.33 kHz spacing. This will be displayed on the LCD screen.
