VIII. DTXPRO-800U SERVICE REQUIREMENTS

Routine maintenance of the DTXPRO-800U consists of cleaning or replacing the air inlet filter. In

normal operating environments this should be done once a month or more often in dusty

environments. Cleaning should be done with a light detergent. Rinse and dry the filter carefully

before installing. Any detergent residue could damage components in the modulator. For this

reason, the first option should be to replace the filter with a new one (PTI Part Number 990202)

The following data should be recorded in the station log. This information should be compared to

previous test recordings to insure normal operations.

1. DC SUPPLY VOLTAGE

2. DC CURRENT

3. OUTPUT POWER PERCENT (%)

4. REFLECTED POWER PERCENT (%)

5. HEAT SINK TEMPERATURE IN DEGREES CELCIUS

Under normal operating conditions is the performance of the adaptive linear and non-linear

correction performance should be checked. This can be done remotely if the unit is connected via

Ethernet or on each visit to the site. Adaptive linear correction is normally placed in the idle mode

once the correction is complete. If so, the corrector can be placed in AUTO RUN for a while to

optimize the correction and then returned to the idle mode.
