Precautions
IMPORTANT!
The Telecommunications Act of 1996, effective February 8,
1996, provides the FCC discretion to eliminate radio station
license requirements for aircraft and ships. At the present time,
you do not need an individual license to operate the VHF 725
aboard your private vessel in many circumstances. To find out
the specific details on whether you are exempt from licensing,
please refer to the FCC Fact Sheet PR 5000 or contact the FCC
at: 1-800-322-1117.
Note that no license is required for a portable radio used
only as a backup on a vessel which already has a station license
per FCC 506 Instructions, dated 1993.
If a marine license is required or desired, contact the FCC
at 1-800-322-1117 to request Form 506, Application for Ship
Radio License.
The FCC also has a fax-on-demand service to provide forms
by fax at 1-202-418-0177.
The VHF 725 user accepts all responsibility for obtaining
the proper licensing before using the transmitter.
WARNING!
This transmitter will operate on frequencies (channels) that

Description
The VHF 725 is a 5 watt marine VHF communications
transceiver in a convenient handheld package.
A keypad located on the front of the unit provides onehand control of communication features. The knobless
design allows push-button Squelch and Volume adjustment.
A single button press provides a manual Squelch Override
function. Tri-Watch monitoring mode allows simultaneous
monitoring of emergency channel (16), calling channel (9)
and a channel selected by the user. The channel 16/9 key
allows you to toggle between emergency and calling
channels.
A 1” high by 1-3/8” wide LCD display provides indication of all features and functions of the VHF 725. The scan
feature allows the operator to select up to 10 channels for
continuous monitoring in any combination of U.S.A.,
Canadian, and International bands.
Unit
The weather channel key toggles between regular
channels and weather channels. It enables the weather alert
mode when pressed and held for more than one second. The
high/low key toggles the transmitter power level from
between five watts and one watt. When held for more than
one second, it locks and unlocks the “Key Lock” function to
prevent inadvertent changing of unit settings and modes.
The power key turns the unit off and on and, when
pressed briefly after the unit is powered on, enables the
display backlighting feature and illuminates the keys on the
front of the unit. The weather/regular channel key enables or
disables the weather alert function.
Small size and light weight characterize the portability of
the GARMIN VHF 725.

Squelch Key - This key breaks the squelch
(unmutes the audio) when pressed and held. It is
also used to set the squelch threshold (the level
at which only strong signals can be received).
The squelch threshold is set by pressing and
holding the squelch key while using the UP/
DOWN keys to adjust the squelch level from 0
to 9. At level 0 (L0), all signals can be heard,
while at level 9 (L9), only the strongest signals
can be heard. Adjusting the squelch level
eliminates weak, unwanted signals, as explained
on page 17.
H/L (High/Low) Power Key - This key toggles
the transmitter power level from High (5 watts)
to Low (1 watt) when pressed and released. It
also locks the keypad when pressed and held for

backlighting key and the Squelch key still
function in the Lock mode. Locking the keypad
prevents inadvertent changing of channel
settings and feature modes.
