UNIDEN MC615
The UNIDEN MC 615 VHF marine radio transceiver has been designed to give you a
rugged reliable instrument that will provide you with years of trouble-free service.
You are encouraged to thoroughly read this manual to acquaint yourself with the
characteristics and operation of your transceiver so that you can contribute to the longevity
of your investment.
With proper care and maintenance, your UNIDEN MC 615 willoutlastyourpresentvessel
and serve you well on board several more. The full features and flexibility designed into this
quality transceiver will prevent it from becoming obsolete regardless of changes in craft
or geographic locations. The unit may be mounted in any number of convenient locations
by utilizingthe universalmountingbracket. I
The UNIDEN MC 615 is of all solid state design with conservatively rated rugged compo-
nents and materials compatible with the marine environment. The transceiver utilizes a
number of gaskets, sealing rings, waterproof membranes, and other sealants to effect
a splashproof housing for protection of the electronics.

INSTAllATION
CAUTION: The MC 615 will operate only with nominal 12 volt negative ground
battery systems.
It is important to carefully determine the most suitable location for your MC 615 on your
vessel. Electrical, mechanical, and environmental considerations must all be taken into
account. You must select the optimum relationship among these considerations.
Keep in mind the flexibility designed into the MC 615 so that you can most conveniently
use your radio. Features which should be considered are:
1. Universal mounting bracket may be installed on eithertop or bottom of shelf, bulkhead,
or overhead mounting.
2. The microphone connector faces forward allowing convenient in-dash or "built-in"
installations.
3. The front panel can be fully reversed to provide for optimum viewing and operating for
any mounting position.
4. The REMOTE speaker jack may be used with an auxiliary speaker.
All.connections are "plug-in" type for easy removal of the radio.
ENGINE NOISE SUPPRESSION
Interference from the impulse noise generated by the electrical systems of engines is
sometimes a problem with radios. The MC 615 has been designed to be essentially
impervious to ignition impulse noise and alternator noise. However, in some installations
it may be necessary to take measures to further reduce the effect of noise interference.
All DC battery wires, antenna lead, and accessory cables should be routed away from the
engine and engine compartment and from power cabling carrying particularly high
currents.
In severe cases of impulse noise interference, it may be necessary to install a noise
suppression kit that is available from your Marine Dealer.

ANTENNA CONSIDERATIONS
A variety of antennas is available from a number of quality suppliers. It is recommended
you draw upon the advice of your Marine Dealer indetermining a suitable antenna for your
vessel and range requirements.
The general rul~s for antennas are: The more gain the greater the range and, the higher
above the water line the greater the range. Antennas should be located so as not to be
in proximity to metal objects. Antennas should not have excessively long coaxial feed
cables.
CHOOSING A LOCATION
Some of the more important external fa,ctors to consider in selecting the location of
your MC 615 are:
1. Select a location that is free from spray and splash.
2. Keep the battery leads as short as possible. Connec:tion directly to the battery is most
desirable. If direct connection cannot be made with the supplied power lead, any
extension should be made with #10 AWG wire. Long extensions should use larger
wire.
3. Keep the antenna lead as short as possible. Long antenna leads can cause substantial
loss of performance for both receiving and transmitting.
4. Locate your antenna as high as possible and clear from metal objects. The reliable
range of coverage is a direct function of antenna hoight.
5. Select a location that does not allowthe radioto bE!subjectedto direct sunlight
(includingthat coming through windows).
6. Select a location that allows free air flow around the heat sink on the rear of the radio.
7. Select a location well away from the ship's compass. Auxiliary speakers also should
be located away from the compass.
After you have carefully considered the various factors affecting your choice of location,
position the radio (with the bracket, microphone, power plug, antenna plug and any
auxiliary plugs installed) into the selected location to assure, there is no interference with
surrounding items. Make the location of the mounting bracket.
Remove the bracket from the radio and use itas a template to mark the holes to be drilled
for the mounting hardware. Drill the holes and mount the bracket with hardware
compatible with the material of the mounting surface. Install the power cable (red is +,
black is -), antenna and all other auxiliary cables and accessories.
Install the radio into the mounting bracket and connect all cables and accessories to the
appropriate jacks and connectors. -4-

1 ROTARY CHANNEL SELECTOR-Selects the desired channel. LED Numerical
channel display shows CH-01 through CH-88.
2 MICROPHONE CONNECTOR -Receptable for microphone connection.
3 ON/OFF VOLUME -Turns power on to radio and allows adjustment to the desired
listening level with clockwise rotation. Whenever the power is turned on, radio auto -
matically goes to Channel 16.
4 SQUELCH -is used to quiet background noise when no signal is being received. Turn
the knob just past the point at which background noise is quieted.
5 DIM/BRIT SELECTOR -This control is used to adjust the brightness of the display.
6 1W/25W SELECTOR - Controls transmitter output power. The 1W (WATT) position
should always be used for in-port or short range communications.
7 CH16 SELECTOR - Provides instant CH16 by overriding Rotary Channel selector.
LED indicator and Channel display will indicate when unit ison Channel 16. But if you
press "OFF", the channel will go back to the one which had been selected with Rotary
Channel. (That is, the channel just before you pressed "CH16".) And also Channel
Display will go back to that channel.
8 TX LED INDICATOR - Glows red in the transmit mode. The transmit lamp is operated
from the actual presence of power transmitted to the antenna.

supplied to mate with this connector. Remember, red is +, black is -. The power cord
is equipped with a fuse to protect the radio. Use only a Six (6) AMPERE fast blow fuse
for replacement.
