Phonecell SX4e Troubleshooting
Telephone Service is Not Working
If the telephone service is not working, first check the operation of the telephone
equipment and wiring connected to your Phonecell. 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 Phonecell 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 Telular distributor.
Unable to Receive Incoming Calls
If more than one telephone or telephone device is connected to your Phonecell,
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 Phonecell’s unit enclosure. Moisture can damage the equipment.
Ventilation is also very important. If there are moisture or ventilation problems, move
your Phonecell to correct as necessary, see the
Temperature Environment section of
this manual.
No Power
The top LED lamp on the front of your Phonecell SX4e indicates the unit’s power
condition. If the LED is YELLOW or GREEN, your Phonecell is receiving power. If
the power cord is connected and the LED lamp is not lit, the Phonecell 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 optional Inline Battery Backup Unit, the unit must be connected to
AC power for at least 24 hours to fully charge the batteries before they’ll provide back-
up power to your Phonecell. Verify that the batteries have been charged for at least 24
hours and that the power source and its corresponding circuit breaker are functioning
properly. Then, examine the batteries for physical damage and corrosion. Replace the
batteries if necessary.
WARNING!
Only Authorized Service Personnel should remove the cover of your
Phonecell. For further assistance, contact your Authorized Telular
Representative. Please have your units model and serial number ready.
