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 work-
ing 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 exten-
sions on your phone line will ring when an incoming call occurs.
Unable to Send and Receive Fax or Data Calls
Because most TDMA and PCS networks do not support digital fax and data services, AMPS 800 MHz
networks and AMPS 800 MHz channels on TDMA 800 MHz networks can be used for fax and data
services. There is no guarantee that the analog channel request will be granted (there may be no
analog channel available). The fax or data call will fail if an analog channel is not assigned. Contact
your local cellular dealer or service provider to determine the availability of an analog channel.
Moisture or Ventilation Problems
Visually inspect your Phonecell unit’s 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 ORANGE 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 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 corre-
sponding circuit breaker are functioning properly. Then, examine the batteries for physical damage
and corrosion. Replace the batteries if necessary.
