SXT-4080 TROUBLESHOOTING
Telephone service is not working.
If the telephone service is not working, first time, check an operation of the telephone equipment and wiring
connected to your SXT-4080. Test the equipment on a different service or piece of equipment to ensure
proper operation, or connect a known good telephone device to the phone port on the SXT-4080 unit. This
will verify the condition of the telephone equipment and the internal wiring of the telephone service to ensure
that it’s working properly. If the telephone system or wiring is not working properly, replace or repair the
equipment as required. Otherwise, contact your cellular provider or your authorized Epivalley distributor.
Unable to Receive Incoming Calls
If more than one telephone or telephone device is connected to your SXT-4080, make sure that all devices
are “on-hook” (hung up). If one extension is “off-hook” (off its cradle), none of the extensions on your phone
line will ring when an incoming call occurs.
Moisture or Ventilation Problems
Visually inspect your SXT-4080’s unit enclosure. Moisture can damage the equipment. Ventilation is also
very important. If there are moisture or ventilation problems, move your SXT-4080 to correct as necessary.
See the Temperature Environment section of this Guide.
No Power
The power LED lamp on the front of your SXT-4080 indicates the unit’s power condition. If the LED is
GREEN, your SXT-4080 is receiving power. If the power cord is connected and the LED lamp is not lit, the
SXT-4080 is not receiving power. Verify that the AC power source and its corresponding circuit breaker are
functioning properly.
Battery Backup Failure
If you’re using the battery, the unit must be connected to AC power for at least ___hours to fully charge the
battery before it will provide back-up power to your SXT-4080. Verify that the battery has been charged for
at least 15 hours and that the power source and its corresponding circuit breaker are functioning properly.
Then, examine the battery for physical damage and corrosion. Replace the battery if necessary.

GENERAL INFORMATION AND SAFETY
Your SXT-4080 Fixed Wireless Terminal (FWT) functions as both a radio transmitter and receiver. When it is
ON, the FWT receives and sends out radio frequency (RF) energy. The CDMA 800 unit operates in the
frequency range between 824 and 894 MHz, and the CDMA 1900 between 1850 MHz and 1990 MHz. Both
employ commonly used phase/frequency modulation techniques. When you use your SXT-4080, the
cellular system handling your call controls the power level at which your unit transmits. Nominal power
output is 230 mW.
WARNING!
Your SXT-4080 must be placed or mounted on a flat surface to allow proper ventilation. Do not block the air
vents or the space beneath your SXT-4080 as this could cause the unit to overheat and fail.
WARNING!
Only Authorized Service Personnel should remove the cover of your SXT-4080. For further assistance, contact
your Authorized Epivalley Representative. Please have your unit’s model and serial number ready.
