Uniden MHS335 Radio Owner’s Manual
INTRODUCTION
Uniden's MHS335BT is a oating, 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
rmware.
FEATURES
Your radio provides the following key features:
x Submersible design. Complies with oating 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 tted. 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.
x Memory Scan mode. Lets you save channels to memory and monitor them in quick
succession.
x High/LO power level select. Lets you boost the transmitter power from 1W to 2.5 or
6W for added transmission distance.
x Battery level display and low battery alert.
x Dual and Triple Watch operation. These different watch modes let you monitor up to
two Coast Guard Distress/Hailing channels and one weather channel along with one
regular marine channel.
x All marine VHF channels for the U.S., Canada, and international waters
x Emergency 16/09 Channel monitoring. Set unit to scan one or both of these
emergency channels regularly within normal scanning cycles.
x Class D second receiver is dedicated to monitoring the DSC watch channel 70 to
ensure that no incoming messages are missed.
x National Oceanic and Atmospheric Administration (NOAA) Weather Channel
watch. Sounds a warning tone when a hazard alert is issued.
x LCD and key backlight/Flashlight/SOS Strobe. Pressing the Light/Lock key initiates
various light options (see Page E-5).
x Key Lock. Locks keys to prevent accidentally changing channels or entering data.
x Selectable Backlight Timer. Lets you select the length of time the backlight will be
on.
x DSC. Lets you call other ships or groups using their unique identication code. This
radio complies with International Class D DSC standards for Handheld GPS/VHF
E-4
Uniden MHS335 Radio Owner’s Manual
marine transceivers.
x GPS (Favorite Position mode). Lets you save your current position as well as
manually enter other positions.You can save positions into a directory to return to them
as desired.
x Bread Crumbs. Tags specic GPS points along your route. You can set how far apart
these points should be (seconds, minute, etc) through the menus.
x Waypoints. Create a list of coordinates and use that list to navigate to various
destinations.
x NMEA input/output. Lets you connect to a chartplotter and, through menus,
determine what NMEA data you want to receive.
x 10 weather channels available for monitoring.
x MOB (Man Overboard). Lets you lock onto the current position when a Man
Overboard situation occurs.
x Compass Display. Lets you determine the way you want the radio to display your
course - by showing your course and direction or by showing location on an north-
south-east-west display. Automatically auto-plots to a received DSC distress call.
