Both Watches and Weather Channel [VHF-FRS]
If both the Weather Alert and the TripleWatch features are
enabled when you press SCAN/MEM, the radio starts
checking the memory channels in ascending order. Then it
checks Channel 9 and 16 every 2 seconds and nally, it
checks the active weather channel approximately every 7
seconds, looking for the alert tone (1050Hz). The radio then
repeats the cycle. If the radio detects a weather alert tone
during the check cycle, it remains on the weather channel

scanning and remains on the detected channel for 2

scanning.
During scanning, you can press SCAN/MEM, 16/9/TRI, or

you used, the screen shows one of the scanned channels,
