The Tone Alert System

The Tone Alert function provides an audible alarm to indicate when someone is transmitting on the frequency you
are monitoring.
If you use the tone alert function with the CTCSS, paging, or DTSS function, you can use the function more
effectively since you can wait for a call from a specific remote station.
If you set the T.ALT function, you will not hear voice communications.
The Automatic Power Off function is disabled during T.ALT operations.
1) Press the BAND key to select the desired band.
2) Adjust the squelch to respective threshold.
3) Select the desired function if you wish to use it.
4) Press the F key, then press the 5 key. The T.ALT indicator (a bell) will appear on the display.
5) The T.ALT and BUSY indicators display and the transceiver beeps on and off for approximately 5 seconds
when a signal is present.
6) The time when the signal was received will be displayed. The time is changed each time when a new signal is
received.
7) Press the PTT switch to release the T.ALT function.
8) Press the F key, then press the 5 key again to completely release the T.ALT function.
Note
For the T.ALT to function properly in CTCSS, the incoming signal must be present for approximately
1 second.
