channel as your second-priority channel (Selecting a Different Second-Priority Channel, page 7).

Switching to Priority Channels
You can quickly switch between your current working channel and a priority channel. When you change to a
priority channel, the transmit power is set to high (25 W) automatically, and when you change back to your
current channel, the transmit-power setting is restored.
On North American models, you can quickly switch between channel 16, your second-priority channel, and your
original channel using the 16/9 key.
On International models, you can quickly switch between channel 16 and your original channel using the 16+
key.

The transmit power changes to high (25 W) automatically. You can select HI/LO > 1W to change the transmit
power to low (1 W).

3 Select 16/9 or 16+ to return to your previous channel and transmit-power setting.
Setting the Receiving Sensitivity
You can control the receiving sensitivity of the radio. When you have noise in high-traffic areas or areas with
electromagnetic interference, such as near cell-phone towers, you can set the receiving sensitivity to LOC to
decrease receiver sensitivity. In remote areas and on open water, you can set the receiving sensitivity to DIST to
ensure that you use the maximum range of the receiver.

• Select LOC to enable local sensitivity.
