You are required to comply with the Rules and Regulations set
forth by the Federal Communications Commission. A complete set
of FCC Marine Radio Rules may be purchased from the US
Government Printing Office by requesting “Volume IV of the FCC
Rules.” Some of the important rules follow:
•You must obtain a Ship’s Station License by making
application to the FCC on FCC Form 506. A copy of this
form is included with your radio. An Interim Ship’s Station
License may be obtained by personal appearance at your
local FCC Field Office. The Ship’s Station License must
be posted at the station location.
•A Restricted Radiotelephone Operator Permit (or higher
grade license) must also be obtained from the FCC in
order to legally operate your transmitter in international
waters. Application is to be made on FCC Form 753. An
interim permit is automatically granted upon submission of
your application.
•You must keep a current copy of the appropriate FCC
Rules.
•You must maintain a log book in which you record all calls
and full transmitter maintenance records.
•Your transmitter must be verified to be in compliance with
current FCC requirements by an appropriately licensed
technician. This has been done at the factory for your
MC535. A signed Certificate of Compliance Card is
included with your radio and should be kept with your log
book.
•You may not make transmitter tuning adjustments unless
you are the holder of a valid first or second class
commercial license issued by the FCC. Please request
the assistance of your Uniden Marine Dealer and your
nearest FCC Field Office if you need other than a Ship’s
Station License.

The Uniden MC535 VHF marine radio transceiver is designed to provide
you with years of trouble-free service. It’s rugged components and
materials are easily capable of withstanding the harsh marine
environment. The transceiver has a splashproof housing to protect the
electronics, and the unit may be mounted in several convenient locations
on-board your vessel using the universal mounting bracket.
You can be confident in your choice of radio equipment because the
MC535 offers Instant Channel 16 access, automatic transmitter time-out,
and complete coverage of the marine frequency band. It will meet your
communication needs by providing you with state-of-the-art radio
electronics that are easy to operate.
We are certain that you will enjoy your MC535. To ensure that you get
the most from its features, please read this operating guide carefully
before using the unit.
Caution: The MC535 will operate only with nominal 12 volt negative
ground battery systems.
Selecting a Location
Before choosing a location for your new MC535, review these guidelines:
•Carefully consider the unit’s electrical and mechanical mounting
requirements, as well as your accessability needs.
•Select a location that allows free air flow around the heat sink in
the back of the radio.
•Select a location that is free from spray and splash and doesn’t
expose your radio to direct sunlight.
•Keep the battery leads as short as possible, and for best results
connect directly to the battery. If the supplied power lead isn’t
long enough to reach the battery, extensions should be made
with at least #10 AWG wire.
•Choose a location for the radio and auxillary speaker (if
installed) that is away from the ship’s compass.
Antenna Considerations
Many different antennas are available for your radio. We recommend that
you consult your Uniden dealer in determining a suitable antenna for your
vessel and range requirements.
In general when choosing or installing your antenna, consider these
guidelines:
•The range increases with a high-gain antenna placed as high as
possible above the water line.
•The antenna should not have an excessively long coaxial feed
cable.
•The antenna should be located away from metal objects.
The MC535 has been designed to minimize ignition and alternator noise.
However, in some installations it may be necessary to take additional
steps to help eliminate noise interference. During installation, try to direct
the DC battery wires, the antenna lead, and accessory cables away from
the engine compartment or ignition and alternator wiring.
If the noise continues, it may be necessary to install a noise suppression
kit. Contact your Uniden dealer for more information.
Installing the MC535
After choosing a location, position the radio (with the bracket,
microphone, power cord, antenna cable, and external speaker lead, if
installed) to make sure it fits. Then follow these steps:
1.Using the bracket as a template, mark the holes for the mounting
hardware.
2.Drill the holes and mount the bracket with hardware appropriate for
the mounting surface.
3.Connect the red power lead
to the positive (+) battery
terminal or to an accessory
contact in your vessel’s fuse
box.
Note:
The power cord is equipped
with a 6-ampere fast blow fuse to
protect your radio. Use only a
6-ampere replacement fuse.
4.Connect the black wire of the power cord to the negative (–)
battery terminal or to a ground source in your vessel’s fuse box.
5.Install the radio in the mounting bracket and connect the antenna
cable and accessories to their appropriate jacks and connectors.
To set the “Squelch Gate” to the desired level, turn
counterclockwise until you hear noise. Then turn
clockwise just until the noise stops. Now only strong signals get
through.

marine frequencies. Certain channels — the weather channels, channel
70 of both the USA and International frequencies, and channel 15 of the
USA frequencies — are receive only. Your radio will not transmit on these
channels. For your reference, a listing of all the available marine
channels is printed on the back cover foldout.
Setting TX Output
Caution: It is important to remember to always use the 1W position in

Note:If the PTT switch is held down and the power is turned on, a
warning tone sounds, the LED display begins to flash, and the
unit will not transmit. The MC535 resets for normal operation
when the PTT switch is released.
Transmitter Time-Out
If the PTT switch on your microphone is held for more than 5-minutes, the
MC535 transmitter automatically shuts off, a warning tone sounds, and
the LED display begins to flash. This prevents damage to your receiver,
and — in the event that the transmission is unintentional —
communication frequencies will not be jammed.
If your MC535 does not perform up to expectations, try the suggestions
listed below. If you cannot get satisfactory results, call the Uniden
Customer Service Center at (800) 586-0409, 8:00 a.m. to 5:00 p.m.,

Your MC535 is a precision piece of electronic equipment and you should
treat it accordingly. Its rugged design requires very little maintenance;
however, these precautions should be observed:
•If your radio has been accidentally sprayed or splashed, you
should immediately wipe it down with a soft cloth dampened with
fresh water.
•If the antenna has been damaged, you should not transmit
except in case of emergency. A defective antenna may cause
damage to your radio.
Since you are responsible for the continued FCC technical compliance of
your radio, we recommend that you arrange for periodic performance
checks with your Uniden Marine Dealer.
Should you find it desirable or necessary to service your MC535,we
suggest you contact the Uniden dealer where your purchase was made.
Your dealer will be able to assist you with complete service information.
If you require service that is within the terms of your warranty you should
present a copy of your receipt to your dealer to authenticate your claim.
If you find it inconvenient to obtain service assistance from a dealer, you
may obtain service from the Factory Service Station. If you want factory
service, please pack your radio in a suitable container that will provide
adequate protection, enclose a note describing the problem and a copy of
your receipt, and send the radio (transportation prepaid) to:
