3 Using the Battery Charger
The Battery Charger
The battery charger charges battery packs in both the spare battery compartment and in the handset when the
handset is placed into the handset cradle. If both are present at the same time, charging in the spare battery
compartment is suspended until the battery pack in the handset is fully charged.

Note: Do not touch, push, or pull any exposed battery contacts.
Battery Charger Features
The battery charger offers these features:
The spare battery compartment refreshes the battery pack automatically by
fully discharging it before recharging it. This process reduces or eliminates the
potential “memory” effect. Memory effect, which reduces a battery’s capacity,
occurs over time when you repeatedly recharge a battery before it is fully
discharged.
The handset cradle charges a battery pack in the handset.
The REFRESH button, when pressed, refreshes the handset battery pack in the
handset cradle by fully discharging the battery pack before recharging it.
The REFRESH and the HANDSET LEDs go on when the REFRESH button is
pressed and stay lit until the battery pack finishes discharging.
The HANDSET LED, when lit, indicates that the handset battery pack is installed
in the handset, and the handset is in the handset cradle.
The SPARE LED, when lit, indicates that a battery pack is in the spare battery
compartment.
Note: Before you use the MDW 9040 Pocket Phone handset for the first time,
the battery pack must be charged.
