MDW 9031/9031DCP Wireless Pocket Phone Installation and Use

The color of the battery charger’s LEDs indicates the state of the corresponding battery pack, as shown in the
following table:
Extending Battery Life
The battery charger will charge a battery pack in the handset if you simply insert the handset in the battery
charger’s handset cradle; however, the Refresh process fully discharges the battery pack before recharging it,
thereby ensuring the best possible charge and the longest talk time.
“Memory effect” reduces a battery's capacity and can occur when you repeatedly recharge a battery pack before
it is fully discharged. The nickel metal hydride battery pack shipped with your MDW 9031/9031DCP is resistant
to the memory effect. Even so, it is recommended that you refresh your battery pack at least once a week.
The following table shows how long refreshing takes using a Model 40B charger, depending on how much
charge is left in the battery pack when you insert it into the charger and press the REFRESH button:

Note: If either the SPARE LED or the HANDSET LED is flashing red, both battery packs must be
removed from the charger to clear the flashing-red condition. Address the possible problems
for one battery pack at a time to determine whether one is bad.
Note: The SPARE LED may turn amber instead of red when jostled in the spare battery charging
compartment. Remove the battery then place it back into the charger to clear the condition.
