WARNING
The Inshore Boating Radio Communications Service is under the jurisdiction of the
Department of Communication (D.O.C.). Any adjustments or alterations which
would alter the performance of the transceiver's original D.O.C. Type Approval or
which would change the frequency determining method are strictly prohibited.
Replacement or substitution of Crystal, Transistors, IC, Regulator Diodes or any
other part of a unique nature, with parts other than those recommended by us, may

INSTAllATION
CAUTION: The UNIDEN MC4300 will operate only with nominal 12 volt negative
ground battery system.
It is important to carefully determine the most suitable location for your UN IDEN
MC4300 on your vessel. Electrical, mechanical, and environmental considerations
must all be taken into account. You must select the optimum relationship among
these considerations.
Some of the more important external factors to consider in selecting the location of
your UNIDEN MC4300 are:
1. Select a location that is free from spray and splash.
2. Keep the battery leads as short as possible. Connection directly to the battery is
most desirable. If direct connection cannot be made with the supplied power lead,
any extension should be made with #14 AWG wire. Long extensions should use
larger wire.
3. Keep the antenna lead as short as possible. Long antenna le~ds can cause sub-
stantialloss 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 height.
