West Marine VHF255 Radio Owner’s Manual
Introduction
Features
Your radio provides the following key features:
Submersible design
Complies with oating JIS8/IPX8 water-resistant
standards, which means the radio can be submerged in
1.5 meters of water for 30 minutes without damage.
The radio will only meet this rating if fully assembled
and all rubber seals and sealing plugs are well
maintained and correctly tted. This means that the
speaker microphone is attached or the sealing plug is
tted, and the battery pack (or case) and antenna are
attached and securely fastened.
After your radio is submerged in water, you might
notice that the sound is distorted. This is because
there is still water remaining in and around the speaker
and microphone. Just shake the radio to clear excess
water, and the sound will return to normal.
If your radio is exposed to salt water, clean it
thoroughly with fresh water.
The charging equipment is not waterproof.
Memory scan mode
Lets you save channels to memory and monitor them in
quick succession.
E-2
West Marine VHF255 Radio Owner’s Manual
Transmitter power level select
Lets you boost the transmitter power from 1 Watt to 2.5 or
5 Watts for added transmission distance.
Battery level icons and low battery alert
Dual, Triple and Quad Watch operation

Coast Guard Distress/Hailing channels and one weather
channel along with one regular marine channel.
All marine VHF channels for the U.S., Canada, and
international waters
FRS/GMRS radio modes
Lets you use your radio to keep in touch with other
members of your party on shore or on another craft close
by.

Setting the
Squelch Level
The squelch feature
reduces static on
the speaker by
ltering out any
background
channel noise. At
the lowest squelch
level, the speaker
plays all signals,
including any channel noise. Setting the squelch level
higher lters out noise and lets only actual radio
transmissions through.
While listening to a channel, adjust the SQUELCH knob
until the noise is ltered and you can hear only the
transmission. If you switch to a channel with a lot of noise
or a weak trans-mission, you may need to readjust the
squelch level again.
Setting the squelch level too high may prevent you from
hearing weaker transmissions. If you are having difculty
hearing a transmission, try setting the squelch level lower.
Changing the Channel
Press Channel up and Channel down briey to scroll through
the channels one channel at a time. Press and hold
Channel up or Channel down to quickly scroll through the
