8. MAINTENANCE INSTRUCTIONS
8.1. Cleaning
AMP Power Amplifiers should be periodically wiped off with a clean, damp cloth. For more thorough
cleaning, dampen a clean cloth with glass cleaner and wipe off unit. Ensure units are completely
disconnected from their power sources before cleaning.
8.2. Troubleshooting
To avoid poor performance, ensure all mating connectors are tightly fastened, clean, and have no pins
bent or damaged.
If poor or no operation is observed, ensure the external DC voltage supply is b11 and +16 Vdc
with correct polarity. All AMP Power Amplifiers have over-voltage and reverse polarity protection circuits.
If the input voltage is over +16 Vdc, remove the DC Power Cable from the unit, reduce the DC voltage to
b11 and +16 Vdc, and reconnect the DC Power. If the input voltage is negative polarity, remove
the DC Power Cable from the unit, reverse the connections between the DC voltage supply and DC
Power Cable, and reconnect the DC Power Cable.
If poor or no operation is still observed, verify that your enable pin (see Section 7.2) and power output
level (see Section 7.3) are set properly for your Power Amplifier and that the output power of your
transmitter matches the acceptable power input range for your Power Amplifier configuration.
If these efforts fail, do not attempt to repair the unit. Please contact AMP with a detailed description of the
problem. Depending on the nature of the problem, AMP may provide further troubleshooting assistance
or advise the entire system be returned for repair and retest.
Caution: Removal of the cover constitutes breaking the seal and VOIDS PRODUCT WARRANTY.
8.3. Preparation for Reshipment
If the power amplifier, and/or any other purchased item(s) are to be shipped to another location or
returned for repair or realignment, use the original packaging or a sturdy box with sufficient protective
material to avoid damage from movement or exposure during transit. Remove all external connections
(cables, antenna, etc.) prior to shipping.
