Maintenance and Troubleshooting 15 - 7

Charge LEDs do not 
light when device is 
inserted.

Cradle is not receiving power.

Ensure the power cable is connected securely to both the 
cradle and to AC power.

Device is not seated correctly in 
the cradle.

Remove and re-insert the device into the cradle, ensuring it is 
correctly seated. 

Extreme battery temperature.

Battery does not charge if battery temperature is below 32°F 
(0°C) or above 104°F (40°C).

Device battery is not 
charging.

Device was removed from cradle 
or cradle was unplugged from 
AC power too soon.

Ensure cradle is receiving power. Ensure device is seated 
correctly. If a device battery is fully depleted, it can take up to 
four hours to fully recharge the Li-ion battery.

Battery is faulty.

Verify that other batteries charge properly. If so, replace the 
faulty battery.

Device is not fully seated in the 
cradle.

Remove and re-insert the device into the cradle, ensuring it is 
correctly seated. 

Extreme battery temperature.

Battery does not charge if battery temperature is below 32°F 
(0°C) or above 104°F (40°C).

During data 
communications, no 
data was transmitted, 
or transmitted data 
was incomplete.

Device removed from cradle 
during communications.

Replace device in cradle and retransmit.

Incorrect cable configuration.

See the system administrator.

Communications software is not 
installed or configured properly.

Perform setup as described in 

Device does not boot 
when placed in the 
cradle.

The device’s battery is 
discharged.

Normal behavior if the battery is severely discharged. The 
battery must charge at a reduced charge rate until the battery 
acquires sufficient charge to boot the device. This can take up 
to two hours, depending on the level of battery discharge.

This can be avoided by powering the cradle with the optional 
external power supply.
