The technical information, diagrams and charts will be supplied upon request. It is the user's responsibility to see that this radio is operating at all times in accordance with the F .C.C. Citizens Radio Service regulations. We highly recommend that you consult a qualified radiotelephone technician for the servicing and alignment of this CB radio product.

Please refer to the WARNING information contained in the 1st page of this Owner's Manual.

(NOTE: When ordering parts, it is essential to specify the correct model number and serial number of the unit.)

MAINTENANCE AND ADJUSTMENT

This transceiver is especially designed for the environment encouuntered in mobile installations. The use of all solid state circuitry and its light weight result in high

reliability. Should failure occur, however, replace parts only with identical parts. Do not substitute.

PREVENTIVE MAINTENANCE

At six to twelve month intervals, the following system checks should be made:

1.Check Standing Wave Ratio (SWR).

2.Inspect all electrical connections to ensure that they are tight.

3.Inspect antenna coaxial cable for wear or breaks on shielding.

4.Inspect all screws and other mounting hardware for tightness.

ADJUSTMENT

This transceiver is factory aligned and should not require any adjustment when used with a 52 ohm antenna. If an antenna other than 52 ohm impedance is used, adjustment of the transmitter output circuit may be made to obtain optimum power transfer to the antenna. This adjustment should be made only by a licensed techni-

cian using a high quality in-line RF wattmeter which will not produce standing waves when inserted in the antenna cable.
