Uniden MC-4700 - Manual (Page 8)

used has been specifically designed for marine applications.
Before installing the transceiver in a boat, consult your dealer for information regard­
ing an adequate grounding system and prevention of electrolysis between fittings in
the hull and water.
AC OPERATION
To operate the transceiver from AC current as the power source, you will require a
separate power supply capable of supplying 2.5 amps at a 13.8V DC output with a
nominal input voltage of 240 volts AC, 50/60 Hz. Simply connect the red (+) and
black (-) leads of the transceiver to the corresponding DC terminals of the power
supply.
NOTE; Do not attempt to operate this transceiver by connecting directly to 240V
AC.
REMOTE SPEAKER
The external speaker jack (EXT. SPKR) on the rear panel is used for remote receiver
monitoring. The external speaker should have 8 ohms impedance. When the external
speaker is plugged in, the internal speaker is disconnected.
PUBLIC ADDRESS
An external 8 ohm 4-watt speaker must be connected to the (PA SPKR) jack located
on the rear panel when the transceiver is used as a public address system. The speaker
should be directed away from the microphone to prevent acoustic feedback. Physical
separation or isolation of the microphone and speaker is important when operating
the PA at high output levels.
OPERATING INSTRUCTIONS
Barracuda operates on 10 AM channels and 10 Upper Side Band channels.
When you receive the SSB signal in the proper mode, audio sound may be either too
high pitched or low pitched, indicating that your receiver may not be tuned to the
exact same frequency as the transmitter to which it is listening. The Barracuda is
equipped with a Clarifier. By tuning the Clarifier, you can slightly change the fre­
quency of the receiver, so you get a normal tone.
