TROUBLESHOOTING
The Mirage C-22-G is designed for long, trouble-free performance and should not require
extensive troubleshooting in the field.
NOTE: In the event of automatic power shut-
down, the amplifier must be turned off, and the cause of shut-down determined and
removed.
In case of difficulty check the following before assuming amplifier
malfunction:
a. Loose antenna or power supply connections.
b. VSWR of antenna system.
c. Coaxial cables from radio to amplifier, and amplifier to antenna.
d. Output voltage of power supply.
e. Power output of radio.
f. Improper fuse rating.
WARNING:
This unit should not be operated with the cover removed The cover
confines R.F. radiation, including harmonics, to the inside of the
case. Operation of the unit without the cover could result in direct
harmonic radiation. The harmonic filters contained in the circuit
will not suppress direct radiation.
IMPORTANT REMINDER
All MIRAGE amplifiers manufactured for amateur radio - with the exception of
repeater amplifiers - are rated as ICAS - Intermittent Commercial and Amateur
Service. This generally means 5 minute duty cycles, i.e. 5 minutes transmitting, 5
minutes receiving.
Although all of our units, except the hand helds, have thermal protection, continued
use where this cut out occurs can damage transistors.
