INTRODUCTION
Uniden's MHS335BT is a floating, hand-held class D DSC radio with an integrated GPS
receiver. It is also Bluetooth capable so you can use Uniden's smartphone app (iOS and
Android) to set up the radio and text message other VHF text message capable radios.
You can enter other information such as DSC directory information and update the radio's
firmware.
FEATURES
Your radio provides the following key features:
xx Submersible design. Complies with floating JIS8/IPX8 water-resistant standards,
which means the radio can be submerged in 4.9 feet of water for up to 30 minutes
without damage.
NOTES:
The radio will only meet this rating if fully assembled and all rubber seals and
bungs are well maintained and correctly fitted. This means that the speaker
microphone bung is inserted, and the battery pack (or case) and antenna are
attached and securely fastened.
After your radio is submerged in water, the sound might be 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 should
return to normal.
If your radio is exposured to salt water, clean it thoroughly with fresh water
and dry it before turning it on.
The charger is not waterproof.

Cautions:
xx
xx
xx
Use only the battery and charger supplied with this radio. Using a different
charger or battery can damage the radio and create a risk of fire or shock.
The charger is not waterproof. If the charger falls into the water, unplug it before
attempting to remove it from the water. After you remove the charger from the
water, please contact Customer Service (see the back cover page for contact
information).
Wipe off dirt or shake water from your radio before placing in the charger if your
radio gets dirty or wet.
Important Notes on Charging the battery
xx
xx
xx
Charge the battery fully before using the radio.
Don’t use the charger when the ambient temperature is below 0° C (32° F) or above
45° C (113° F).

powered on, the battery takes longer to charge.)
SETTING UP YOUR RADIO
TURNING IT ON
Press the POWER key for at least two seconds until the UNIDEN splash screen displays.
Release the POWER key. Press and hold it to turn the unit off.
ENTERING THE USER MMSI
When you power up your radio for the first time, it displays MMSI Not Entered and then
displays a Marine mode screen. User MMSI numbers are unique and cannot be entered
more than once. See Page E-28 for general information about MMSI numbers and how to
get your specific User MMSI number and enter it.
If you must change your user MMSI, instructions are on the Uniden website (www.uniden.
com).
E-24
Uniden MHS335 Radio Owner’s Manual
if you choose to not enter your specific MMSI number at initial start up, you can still use
many of your radio's features. However, you cannot use DSC features.
SETTING IT UP
Even though you can change your radio’s settings at any time, you will probably want to
establish initial settings when you turn it on for the first time. You can adjust some of these
settings on an as-needed basis, but some settings might only be set once and not need
adjustment at all.
Acquiring GPS Location
The MHS335BT automatically acquires your current GPS location when it is turned on.
Turn on the radio and point the antenna towards the sky. It will triangulate your location and
save it.
NOTE: Do not let anything obstruct the antenna, such as a metal cabin ceiling. If the radio displays
an Unable to Aquire message, move to an unobstructed location for the antenna.
Changing the Volume
To change the speaker volume, press VOL/SQ to enter Volume Setting mode. Press ▲ to
increase the volume or ▼ to decrease it (Volume levels = 0 - 15).
Setting the Squelch Level
The MHS335BT recognizes signals as transmissions if they exceed a signal strength
threshold. Adjusting the squelch sets this threshold level. Increasing squelch requires a
signal to be stronger to be seen as a transmission. If you set the squelch too high, you
will risk not receiving transmissions that are lower than that threshold. Reducing the
squelch allows weaker signals to be accepted. However, if you lower the squelch too
much, you will hear white noise all the time.
The squelch feature reduces static on the speaker by filtering out any background
channel noise. At the lowest squelch level, the speaker plays all signals, including any
channel noise. Setting the squelch level higher filters out noise and lets only actual radio
transmissions through.
While listening to a channel, press and hold VOL/SQ to enter Squelch Setting mode. Press
▲ to increase the volume or ▼ to decrease it (Squelch levels = 0 - 15). The following
graphic shows squelch set high enough that only the strongest signals get through.
STRONG SIG.
MEDIUM SIG.

NOTE: Setting the squelch level too high may prevent you from hearing weaker transmissions. If
you are having difficulty hearing a transmission, try setting the squelch level lower.

DIGITAL SELECTIVE CALLING FEATURES (DSC)
WHAT IS DSC?
Digital Selective Calling (DSC) is a standard that allows you to call other ships using their
unique identification 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 key, 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.
MMSI NUMBERS
In order to use DSC features, you must be assigned an individual User MMSI number and
program that number into your radio.
You can get more information on MMSI numbers at these resources:

Safety warnings (e.g., debris
in the water) or any urgent
situation.
Suppose you are coordinating safety for a sailboat race. Before the race starts, you instruct
all the racers to enter your group MMSI number into their radios. During the race:
xx Throughout the race, you use group calling to update the racers on the time, race
status, and any course corrections.
xx A power boat full of spectators comes too close to the race path. You use individual
calling to contact the power boat and advise them to stay clear of the race.
xx You see a rowboat entering the area, but since it doesn’t have a radio, you can’t
communicate with the rowboat. You use all ships calling to alert all the other ships in
the area of the possible danger.

Types of Events
xx
xx
xx
xx
A WARNING is an event that alone poses a significant threat to public safety and/or
property, probability of occurrence and location is high, and the onset time is relatively
short.
A WATCH meets the classification of a warning, but either the onset time, probability
of occurrance, or location is uncertain.
An EMERGENCY is an event that, by itself, would not kill or injure or do property
damage, but indirectly may cause other things to happen that result in a hazard. For
example, a major power or telephone loss in a large city alone is not a direct hazard,
but disruption to other critical services could create a variety of conditions that could
directly threaten public safety.
A STATEMENT is a message containing follow up information to a warning, watch, or
emergency.

WARNING! Read this information before using the radio.
MARITIME RADIO SERVICES OPERATION
Warning! This transmitter will operate on channels/frequencies that have restricted use in the
United States. The channel assignments include frequencies assigned for exclusive use of the
U.S. Coast Guard, use in Canada, and use in international waters. Operation on these frequencies
without proper authorization is strictly forbidden. See page E-44 for tables of the available channels
and their uses. If you are still not certain which channels to use, see the FCC maritime radio page at
the FCC website (http://wireless.fcc.gov/marine/) or contact the FCC Call Center at 1-888-CALLFCC. For individuals requiring a license, such as commercial users, you should obtain a license

BASIC RADIO GUIDELINES
You should familiarize yourself with the rules on marine radios and be aware of which rules apply
to your ship. Complete guidelines for all ship and marine radio types can be found at the US Coast
Guard website under the topic Radio Info for Boaters (the direct link is http://www.navcen.uscg.
gov/?pageName=mtBoater. Here are a few guidelines that affect nearly all boaters.
•
If you have a VHF radio on your ship, you must maintain a watch on channel 16 (156.800 MHz)
whenever the radio is not being used to communicate. Starting in 2004, if a radio is carried, it
must be on and set to channel 16. Wwhenever your ship is underway.
•
If you hear a distress call, wait a few minutes to let a shore station or Coast Guard ship
respond. If no other station has responded after 5 minutes, you must respond to the distress
call.
•
Do not make false mayday or distress calls as a prank or to test your radio. (This is essentially

approved by Uniden could void the user’s authority to operate the equipment.
In August 1996 the Federal Communications Commission (FCC) of the United States with its action
in Report and Order FCC 96-326 adopted an updated safety standard for human exposure to radio
frequency electromagnetic energy emitted by FCC regulated transmitters. Those guidelines are
consistent with the safety standard previously set by both U.S. and international standards bodies.
The design of the radio complies with the FCC guidelines and these international standards.
Uniden MHS335 Radio Owner’s Manual
E-51
Never allow children to operate the radio without adult supervision and the knowledge of the
following guidelines.
WARNING! It is up to the user to properly operate this radio transmitter to insure safe operation.
Please adhere to the following:
Use only the supplied or an approved antenna. Unauthorized antennas, modifications, or
attachments could impair call quality, damage the radio, or violate FCC regulations.
Do not use the radio with a damaged antenna. If a damaged antenna comes into contact with the
skin, a minor burn may result. Please contact your local dealer for a replacement antenna.
To maintain compliance with FCC RF exposure requirements, the radio must be used with a
maximum duty cycle not exceeding 50% in a typical push-to-talk radio use time. DO NOT transmit
for more than 50% of total radio use time.
Body-Worn Operation
This device was tested for typical body-worn operations using the supplied belt-clip. To maintain
compliance with FCC RF exposure requirements, body-worn operations are restricted to the
supplied belt-clip. For hand-held operation, the radio should be held 1 inch from the user’s face. The
use of accessories that do not satisfy these requirements may not comply with FCC RF exposure
requirements and should be avoided. For more information about RF exposure, please visit the FCC
website at www.fcc.gov.
Lithium Ion Battery Warning
This equipment contains a rechargeable Lithium Ion battery. The rechargeable Lithium Ion battery
contained in this equipment may explode if disposed of in a fire.
Do not short-circuit the battery.
Do not charge the rechargeable battery used in this equipment in any charger other than the one
specified in the owner’s manual. Using another charger may damage the battery or cause the
battery to explode.
NOTE: Li-Ion batteries must be recycled or disposed of properly.
Avoid exposing the battery (whether attached to the radio or not) to direct sunlight, heated cars, or
temperatures below -4°F (-20°C) or above +140°F (+60°C). Exposing the chemical contained within
the battery pack to temperatures above +140°F (+60°C) may cause the battery to rupture, fail, or
reduce performance.
