period (10 to 600 seconds), and then automatically switches to channel 16.
Within the programmed timer period, the following action can be taken:

● When the [CLR] key is pressed, the Auto Tune Timer is cancelled, and the transceiver remains on the normal operating channel.
The transceiver operation may differ, depending on the combination of the Auto Switch function and the Auto Tune Timer settings.
