PREVENTIVE MAINTENANCE
Every six months:
• Check the Standing Wave Ratio (SWR).
• Be sure all electrical connections are tight.
• Inspect antenna coaxial cable for wear or breaks in shielding.
• Be sure all screws and mounting hardware are tight.
The PC68LTX is designed to give you years of trouble-free service. There
are no user-serviceable parts inside. Except for the fuse in the DC power
cord, no maintenance is required.
To replace a blown fuse:
1. Press ends of the fuse holder together. Twist to open. Carefully
separate the two pieces.
2. Remove the fuse and inspect. If blown, replace with the same
type fuse.
Use only the fuse specified for your PC68LTX. Failure to do so may void
your warranty.
