Maintenance - Realistic TRC-490-18 Owner's Manual

MAINTENANCE
Since only the finest quality parts are used throughout your Transceiver (and these are all conservatively
rated), you will need little or no service or repair of the unit.
Be sure you treat it with the care deserving of such a piece of electronic equipment. It is rugged and
designed for either base or mobile use—but do not abuse it. Be sure you always make proper connections
and adequate mounting provisions.
If you run into problems with the unit, we recommend you check the following:
1. If trouble is experienced with receiving.
• Check the VOLUME On/Off switch setting.
• Be sure SQUELCH is adjusted properly. Is it over-squelched?
• Check if the unit is switched to an operating channel.
2. If trouble is experienced with transmitting.
• Check if the transmission line is securely connected to the ANTENNA Connector.
• Check to be sure the antenna is OK.
• Are all transmission line connections secure and free of corrosion?
• Make sure you are fully pressing the. Push-To-Talk Button on the Mic.
• Be sure Mic connector is firmly pressed into its jack.
3. If the Transceiver is completely inoperative.
• Check the power cable and in line fuse (4A).
• Be sure DC-AC switch is in correct position.
If these checks don't solve the trouble, do NOT attempt repairs or adjustments yourself. The unit should
be serviced only by a qualified radio technician. Whenever possible, return the unit to the store from
which it was purchased.
WARNING
Do not open up the Transceiver to make any internal adjustments. Only a technician qualified and
recognized by Department of Communication can make internal adjustment of a CB unit.
