6.03 APPENDIX C: OPERATING TEMPERATURE CHARACTERISTICS

The following table is provided for your reference for normal operating conditions of the PX50.

Check the transmitter running temperature in the Temperature Display Screen, and use the

chart below to verify your transmitter is operating within specification at your ambient tem-

perature.

If your temperatures are significantly higher than those show, check for restricted airflow in

the PX50 and clean or replace the air filters in the front panel air intake.

The key to a continuous duty, long running transmitter is keeping it cool. Make sure not to

block the airflow to the transmitter, and to frequently check the air filters. The PX50 has an

automatic over temperature shutdown at 70° C Running the PX50 hot will shorten its lifespan

considerably, especially at temperatures over 60° C. Be sure to use this product in a well ven-

tilated or air conditioned room, and DO NOT BLOCK THE AIR VENTS! The PX50 does have

over-temperature protection, but it is meant to shut down only at extreme temperatures to

prevent short-term damage. The normal shutoff temperature is 70° C.
