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.
4
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 frequency band, transmissions on channels 13 and 67 must be low
(1 W) by default.
In the International channel band, transmissions on channels 15 and 17 must be
low (1 W), and the radio does not allow transmissions on these channels to be
changed to high (25 W).
1 Select HI/LO.
2
Select 1W or 25W.
Digital Selective Calling
NOTE: Before you can use DSC capabilities, you must enter a Mobile Marine
Safety Identity (MMSI) number. An MMSI number identifies each DSC radio, like
a telephone number.
Digital Selective Calling (DSC) is a key component of the Global Maritime
Distress and Safety System (GMDSS). DSC enables VHF radios to place and
receive digital calls directly with other vessels and shore stations, including the
USA and Canadian Coast Guards. Your radio includes full Class-D DSC
capabilities.
For more information about DSC on your device, including using DSC for distress
calls, see the online owner's manual (page 6).
NOTE: The device disables DSC automatically when you turn on ATIS
(page 5).
Entering Your MMSI Number
NOTICE
You can enter your MMSI number only once. If you must change your MMSI
number after entering it, you must take your radio to your Garmin
reprogramming.
