Maintenance and Troubleshooting
Solution
Ensure the power cable is connected securely

Plug the terminal and modem back into the AC
power source. If a battery pack is fully depleted,
it can take 4 hours to fully recharge a 1950 mAh
battery (if the terminal is suspended) and longer
if the terminal is operating.
Verify that other batteries charge properly. If so,
replace the faulty battery.
Remove and re-attach the MDM8100, ensure it
is firmly attached on the bottom of the terminal.
Verify that the battery is charging by tapping
Start - Settings - System - Power.
Ensure the modem cable is connected securely
to both the MDM8100 and to the telephone
jack.
Remove and re-attach the MDM8100, ensure it
is firmly attached on the bottom of the terminal.
Reinstall or reconfigure software (see
Communication Software Installation
4-3).
Connect a conventional telephone and dial the
remote modem to verify the telephone lines are
functioning properly. You should hear the
remote modem answer the call and emit
answering tones. If not, contact the remote
System Administrator.
Ensure you have a charged battery. Use an
external DC power adaptor to recharge the
battery.
