Normal mode with Weather Alert Watch
If you activate Weather Alert Watch
while operating in normal mode,
the radio checks the most recentlyused weather channel every seven
seconds. If it detects a weather
alert for your area, it will change the
channel to the last-used weather
channel. The radio will not check
the weather channel while you are actively transmitting; it waits until your
transmission is nished and then checks the weather channel.

alert you of other hazards besides weather (child abduction alerts, nuclear,
biological, etc.). In weather mode, the radio monitors one of the ten NOAA
weather channels. If any type of alert is received for your area, the radio
sounds an alert tone and displays the type of alert. In weather mode, the
display shows the following:

Weather mode can lter out alerts that do not affect your location if

Weather mode with Weather Alert Watch
Because weather mode already monitors the weather channels, you don’t
need Weather Alert Watch to check the weather channel every seven
seconds. If you activate Weather Alert Watch while operating in weather
mode, it operates as a type of “sleep mode”: the radio stays on the weather
channel and mutes the speaker. If an alert is detected for your area, the
radio sounds an alert tone and turns the speaker back on. This mode is very
useful when you are anchoring for the night but want to stay informed of any
hazards in your area.
Press and hold the WX-ALERT button for two seconds to turn Weather Alert
Watch on or off.
Weather mode with Triple and Dual Watch
If you activate Triple Watch while operating in weather mode, the radio
checks channels 16 and 9 every two seconds; with Dual Watch turned on, the
radio only checks channel 16.
To turn off the radio’s alert tone, press any button.
To cancel weather mode and return to the previous marine channel,
press the WX-ALERT button again.
Press and hold the 16/9-TRI button (on the radio or the microphone) for two
seconds to turn Triple/Dual Watch on or off. (To change between Triple or
Dual Watch, see page 21.)

Setting the volume
Turn the volume knob clockwise to increase the speaker volume; turn it
counter-clockwise to decrease the volume.
Setting the squelch level
The squelch feature reduces the level of static on the speaker by ltering out
the background channel noise. At the lowest squelch level, the speaker plays
all radio signals, including any noise on the channel. Setting the squelch
level higher lters out channel noise and lets only actual radio transmissions
through.
E-19
Using Your Radio
While listening to a channel, adjust the SQUELCH knob until the noise is
ltered out and you can only hear the transmission. If you switch to a channel
with a lot of noise or with a weak transmission, you may need to adjust the
squelch level again.
NOTE: 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.

NOTE: By default, when you change to channel 16, the radio automatically
boosts the power to 25 Watts. Be sure to change the power back to 1 Watt if
you are not making an emergency transmission.
Some channels (for example, channels 13 and 67) limit the power of
transmission to 1 Watt so that there is less interference between boaters
attempting to use the channel at the same time. If you switch to one of these
channels, the radio changes back to 1 Watt automatically. See the channel
list on page 58 for a list of power-restricted channels.
Choosing Triple Watch or Dual Watch
In Triple Watch mode, the radio briey checks channels 16 and 9 every two
seconds. In Dual Watch mode, the radio checks channel 16 only. Generally,
Triple Watch is used in areas where channel 9 is used as a hailing frequency,
while Dual Watch is used in areas where channel 16 is used for distress and
hailing. Your radio comes set to use Triple Watch; if you want to use Dual
Watch instead, you will have to select it in the setup:

Using FIPS codes for weather alerts
The US National Weather Service established 6-digit Federal Information
Processing System (FIPS) codes to issue weather alerts in specic areas.
You can choose which areas you want to hear alerts for by entering these
FIPS codes in your radio. This can prevent you from being bothered by
events that are far from where you are boating. The radio only sounds the
alert tone if an incoming FIPS code matches one of the areas you selected.

Using Digital Selective Calling (DSC) Features
Using Digital Selective Calling (DSC) Features
What is DSC?
Digital Selective Calling or DSC is a standard that allows you to call other
stations using their unique identication code (the Maritime Mobile Service
Identity or MMSI number), just like you would call a phone number. To call
another station, just enter that station’s MMSI number and choose the
voice channel you want to talk on. The radio uses channel 70 to transmit
your MMSI number to the other station along with the voice channel you
requested. If the other station accepts your call, both radios automatically
switch to the requested voice channel so you can talk to the other station.
DSC provides a system for automated distress calls. At the touch of a
button, the radio can transmit your MMSI number, the nature of your
distress, and your current position based on data from your GPS receiver.
The radio repeats the distress call every few minutes until it receives an
acknowledgement.
The DSC standard dedicates a VHF channel—channel 70—to digital
transmissions only. Since digital transmissions require less bandwidth voice
transmissions, channel 70 avoids the problems of busy voice channels.
Advanced DSC features
The UM425 supports the following DSC features:
