Section V Maintenance and Adjustment
The COBRA 148GTL transceiver is specifically designed for the environment
encountered in mobile installations. The use of all solid state circuitry and its light
weight result in high reliability. Should a failure occur, however, replace parts
only with identical parts. Do not substitute. Refer to the schematic diagram and
parts list.
NOTE
If the performance described in the OPERATION and MAINTENANCE
AND ADJUSTMENT sections is not obtained, review the operating
instructions to insure that proper procedures were followed. If a problem
still exists, please contact your local dealer.
