Choosing Triple Watch or Dual Watch
In Triple Watch mode, the radio checks channels 16 and 9
every two seconds. In Dual Watch mode, the radio checks
channel 16 only. Generally, Triple Watch is used in areas
where channel 9 is used as a hailing frequency, while Dual
Watch is used in areas where channel 16 is used for distress
and hailing. Your radio comes set to use Triple Watch; if you
want to use Dual Watch instead, follow the steps below:
Open the menu and choose
Dual/Tri Watch.
Highlight 16 DualWatch and
press the ENTER button. The
radio activates the new setting
and returns to the menu.
To reactivate Triple Watch, repeat the step described
above, but choose 16/9 TriWatch.
Setting the UIC channel mode (USA/CAN/INT)
The radio comes preset to use the channels assigned for
the US. If your current area uses Canadian or international
channels, follow these steps to change the channel mode:
Open the menu and choose USA/CAN/INT.
Highlight the channel mode you want to use: US (USA
Mode), Canadian (Canadian Mode), or international
(Intl Mode).
Press the
ENTER button. The radio activates the new
channel mode and exits the menu.

common name in your local area, you can change the name
of that channel to make it easier for you to use (see the
channel lists starting on page 42 for the default channel
