Monitoring Multiple Channels

Before you can monitor multiple channels, you must turn off

ATIS

(Automatic Transmitter Identification System, page

You can monitor priority channels and the currently selected

channel for broadcasting activity. Channel 16 is the first-priority

channel on your radio. Channel 9 is the default second-priority

channel. You can program a different channel as your second-

priority channel

(Selecting a Different Second-Priority Channel,

page

3).

Select WATCH.

Monitoring Two Channels

You can monitor your current channel and channel 16 at the

same time.

Select WATCH > DUAL.

DUAL WATCH and the channels you are monitoring appear

on the screen. For example, DUAL WATCH CH:, and 16 + 9.

Monitoring Three Channels

You can monitor your current channel, channel 16, and your

second-priority channel at the same time.

Select WATCH > TRI.

TRI WATCH, your current channel, channel 16, and your

second-priority channel appear on the screen. For example,

TRI WATCH CH:, and 75 + 16 + 9.

Selecting a Different Second-Priority

Channel

You can select a channel other than channel 9 as your second-

priority channel.

Select MENU > CHANNEL > 2ND PRIORITY.

Select an option:

• On the radio, turn the SELECT dial to the preferred

channel.

• On the handset, select

channel.

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.

to find the preferred

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).

On North American models, select 16/9 to switch to your

second-priority channel.

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 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).

Select HI/LO.

Select 1W or 25W.

Select OK.

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.
