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 cause violation of the technical regulations of the D.O.C. Rules.

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.
