Note that your handset will consume power both during talk time (when the handset is turned on) and during
standby time (when the handset is turned off, but out of the battery charger). The following chart illustrates
typical power usage:
As a guideline, you can expect a 1-hour reduction in talk time for every 7 hours of standby time. Similarly, you
can expect a 7-hour reduction in standby time for every hour of talk time.
It is highly recommended that you purchase a second battery pack to use as a spare. With the spare battery pack
in the spare battery compartment of the battery charger, you are assured of always having a fresh, usable battery
pack.
The following steps will ensure an uninterrupted supply of power to your MDW 9040
Pocket Phone:
• If you have only one battery pack, be sure to refresh it at least once a week. You
can refresh it by:
~ Placing it in the spare battery compartment of the battery charger.
~ Leaving it in the handset, placing the handset in the handset cradle of the
battery charger, and pressing the REFRESH button.
• If you have two battery packs, exchange the packs between the handset and the
spare battery compartment at least once a week, so that each battery pack is
automatically refreshed. (Alternate the battery packs even if the handset battery
never flashes the Battery icon in the handset display to indicate a low battery
condition.)
• The average battery life for both the standard and the extended battery packs is
approximately one year, assuming that the battery is discharged and charged once
a day. If the battery packs are discharged and charged twice a day, the life
expectancy is approximately six months.
~ Insert the battery pack in the spare battery compartment of the battery charger
and leave it there until the SPARE LED is steady green. Remove the battery
pack from the charger, then reinsert it, and leave it until the SPARE LED is
steady green a second time.
~ OR, with the battery pack in the handset, insert the handset in the handset
cradle, press REFRESH, and leave it there until the HANDSET LED is
steady green. Remove the handset from the handset cradle, then reinsert it,
press REFRESH again, and leave it until the HANDSET LED is steady green
a second time.
