Phonecell SX4D Troubleshooting
Cellular Telephone Service is Not Working
If the cellular telephone service is not working, contact your cellular provider.
Unable to Receive Incoming Calls
Verify that the Phonecell SX4D is “on-hook” (hung up).
Moisture or Ventilation Problems
Visually inspect your Phonecell SX4D’s enclosure. Moisture can damage the
equipment. Ventilation is also very important. If there are moisture or ventilation
problems, move your Phonecell SX4D to correct as necessary, see the
Temperature Environment section of this manual.
No Power
To properly operate, the Phonecell SX4D must either be connected to AC power
or have the required batteries loaded in the battery compartment. Upon loss of
power to the Phonecell SX4D, verify proper connection to AC. If AC power is
unavailable, verify that the batteries are in good condition and that the battery
switch is in the battery power active position.
Battery Backup Failure
The Phonecell SX4D can accommodate 6 standard AAA alkaline batteries for
operation when AC power is not available. A switch is used to select either AC or
internal battery operation. When the internal battery operation is selected, the
Phonecell SX4D will operate for approximately 10 minutes of talk time with fresh
batteries. Replace the batteries if necessary.
NOTE: The Phonecell SX4D does not support rechargeable batteries
WARNING!
Only Authorized Service Personnel should remove the cover of your
Phonecell SX4D. For further assistance, contact your Authorized Telular
Representative. Please have the model and serial number ready (model and
serial numbers are located on the label on the bottom of the unit).
