TROUBLESHOOTING

The Mirage B-320-G is designed for long, trouble-free
performance and should not require extensive troubleshooting in
the field. If difficulty is encountered, check the following before
assuming the amplifier has a malfunction:

1. Loose antenna or power supply connections

2. SWR of the antenna system

3. Coaxial cables form radio to amplifier, and amplifier to
antenna

4. Output voltage of power supply

5. Power output of radio

6. Improper fuse rating
