International/Canada/USA Channel Maps

Three (3) sets of VHF Channel Maps have been established

for marine use: International, Canada and USA. Most of the

channels are the same for all three (3) maps, but there are

definite differences (see table in the Apendix on page 50).

Your radio has all three (3) maps built into it and will operate

correctly in whichever area you choose.

To Set Channel Map Operating Area:

1. The Channel Map mode is the second mode on

the Marine (VHF) Setup programming.

2. U, I and C will display, with the current setting

(the I icon is the default) flashing.

3. Press Channel Up/Down button to select the

I, C or U icon.

4. Press Call/Enter/Setup button to save this entry

and move to the next Setup mode programming.

NOTE

One or two of the channel maps might have been

disabled for sales of this radio in some countries.

Call Tone Alert

If Call Tone Alert is set to On, the radio will alert you to a call

from a compatible Cobra radio with a Call Alert.

To Set Call Tone On or Off:

1. Display will show Call Tone icon and ON or OFF

flashing.

2. Press Channel UP/Down button to select ON or OFF.

3. Press the Call/Enter/Setup button to save this entry

and move to the next Setup mode programming.

The Call Tone icon will show in the Standby mode

when set to ON.

Call Tone Select

This setting will also allow you to transmit a unique

Call Tone alert to identify your radio when you transmit

messages. You can select from one of 10 different

Call Tone signals.

Squelch Control

Squelch Control filters weak signals and radio frequency (RF)

noise so that you will clearly hear the signals you want.

The Squelch Control on this radio is set through the following

keypad operation.

To Set Squelch Control:

1. With the power On, press and hold Call/Enter/Setup

button to access the Setup menu.

2. Squelch control will be the first menu item to appear.

Press the Channel Up and Channel Down buttons to

set level. The signal level bar graph shows squelch

level while you are in Setup mode on the squelch

adjust function.

3. To tune your squelch, press the Channel Down

button until you hear a hissing sound, then press

and release the Channel Up button until the hissing

stops. This will establish a “Baseline” squelch.

4. By pressing the Channel Up button further, you will

filter weak and medium strength signals. By pressing

Channel Down button, you will receive weaker

signals.

5. Press the Call/Enter/Setup button to save this entry

and move to the next Setup mode programming.

NOTE

If the Squelch is set so that you can hear a continuous

hissing sound, the Memory Scan and Tri-Watch

functions will be blocked.
