scroll quickly down the channels.

Normal mode with Weather Alert Watch
If you activate Weather Alert Watch while operating in normal mode, the radio checks the most recently-used weather
channel every seven seconds. If it detects a weather alert for your area, it will change the channel to the last-used
weather channel. The radio will not check the weather channel while you are actively transmitting; it waits until your
transmission is finished and then checks the weather channel.
To turn Weather Alert Watch on or off, press and hold CALL-MENU while the radio is idle. Select Setup and then
WX-Alert Mode. Use CHANNEL UP and CHANNEL DOWN to choose WX Alert Mode setting ON or Off.
Normal mode with Triple and Dual Watch
If you activate Triple Watch while operating in normal mode, the radio checks channels 16 and 9 every two seconds; with Dual Watch
turned on, the radio only checks channel 16. The radio will not check channels 16 or 9 while you are actively transmitting; it waits
until your transmission is finished and then checks the channels.
Press and hold 16/9-TRI (on the radio or the microphone) for two seconds to turn Triple/Dual Watch on or off. (To change between
Triple or Dual Watch, see page 10.)
Normal mode with both Weather Alert and Triple/Dual Watch
You can activate Weather Alert Watch and Triple/ Dual Watch at the same time. The radio performs both checks at their scheduled
time.
