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. For more information about the battery
charger, see “The Battery Charger” in Chapter 2.
“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 9040 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, depending on how much charge is left in the battery pack
when you insert it into the charger and press the REFRESH button:
