Tone Search
When the CTCSS tone being transmitted by another station is not known, you can tune
the radio to the incoming signal and activate tone scan to search for and identify the tone
being used.
To scan for the tone in use:
1. Set the transceiver up for CTCSS Decod-
er operation (see the description in the box
shown below.).
"T SQ" will appear on the display.
2. Press the Programmable key on the MH-48A6JA Microphone that is assigned "CD
SRCH" (see page 4) to start scanning for the incoming CTCSS code.
3. When the radio detects the correct tone, scanning will halt on that tone, and audio will
be allowed to pass.
4. Press the assigned Programmable key of the Microphone to lock in that tone and exit
to normal operation.
Note: You may listen to the (muted) signals from the other stations during Tone Scanning
when Set Mode Item "TS MUTE 44" is set to "OFF". See page 33 for details.
You can also change the Tone Search scanning speed, using Set Mode Item "TS
SPEED 45" See page 33 for details.
