Selecting a Different Second-Priority Channel
You can select a channel other than channel 9 as your second-priority channel.
1 Select MENU > CHANNEL > 2ND PRIORITY.
2 Turn the ENTER dial to the preferred channel.
3 Select OK.
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.
1 To switch from your current channel to channel 16, select 16/9 or 16+.
The transmit power changes to high (25 W) automatically. You can select HI/LO > 1W to change the
transmit power to low (1 W).
2 On North American models, select 16/9 to switch to your second-priority channel.
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.
1 Select HI/LO.
2 Select an option:
• Select LOC to enable local sensitivity.
• Select DIST to enable distant sensitivity.
Switching Between 1 W and 25 W Transmitting Modes
You can control the transmitting power of the radio. Low (1 W) is used for local transmissions, and high (25 W)
is used for distance and distress transmissions.
When two signals broadcast on the same frequency, a VHF radio receives only the stronger of the two signals.
You should transmit calls other than distress calls using the lowest power setting that allows you to
communicate, to reduce the possibility that your transmissions interfere with the transmissions of others.
In the USA channel band, transmissions on channels 13, 17, 67, and 77 must be low (1 W) by default.
In the Canadian channel band, transmissions on channels 13, 15, 17, 20, 1066, 67, 75, 76, and 77 must be low
(1 W) by default.
In the International channel band, transmissions on channels 15, 17, 75, and 76 must be low (1 W).
NOTE: In the USA and Canadian channel bands, you can bypass the power setting for these channels
temporarily during transmission (
Bypassing the Low Transmission Power Setting, page 8
). In the International
channel band, the radio does not permit transmissions on these channels to be changed to high (25 W).
1 Select HI/LO.
2 Select 1W or 25W.
3 Select OK.
