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.

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 HI/LO.

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
2). In the International channel band, the radio does not
permit transmissions on these channels to be changed to high
(25 W).

Using the Hailer
Before you can use the hailer function, you must provide and
install a hailer horn on your boat deck or tower (optional). For
more information, see the Installation Instructions.
The hailer allows you to make on-boat or ship-to-shore
announcements, and allows two-way communications between
connected radios. You can address the ship using the radio or
handset, and sounds received through the horn can be heard
through the radio speaker. For vessels with enclosed cabins, the
hailer allows you to hear sounds from the deck.
NOTE: Hailer functionality is not available on all VHF radio
models.
NOTE: When the radio is in hailer mode, it does not receive
broadcasts from the currently active channel.
