The Handset of your VTech VT
1721 cordless telephone is powered
by a rechargeable battery pack. It
charges automatically whenever the
Handset is in the Base Unit. You should
charge the battery pack for 16 hours
when you first receive your phone.
You’ll know the battery pack needs
charging when:
• The low battery message is dis-
played:
• The Handset seems completely
dead, the LCD is completely clear
and does not activate when you
press the keys.
TO CHARGE THE BATTERY
PACK
To charge the battery pack, place the
Handset in the Base Unit. The
CHARGING indicator will light to show
the Handset is seated properly and the
battery pack is charging. It is recom-
mended that the battery pack be
charged for at least 16 hours initially.
Afterwards, 8 hours of maintenance
charging should be sufficient. You can
use your telephone before that with
diminished capacity, but it is best to
charge the battery pack fully. It will take
several recharge cycles to maximize
the charge capacity of your battery
pack. The maximum battery life be-
INSTALLING THE BATTERY PACK
tween charges is 7 hours of continu-
ous talk time or 14 days of stand by.
Alternatively, if you have purchased
a spare battery pack and it has been
charging in the Base Unit, simply ex-
change the drained Handset battery
pack with the fully charged replace-
ment battery pack from the Base Unit
charger. Place the drained Handset
battery pack into the Base Unit charger
so that it will charge.
The Base Unit spare battery charger
does NOT charge a battery pack as
quickly as the main Handset battery
charger. A full charge requires 24
hours.
A WORD ABOUT RECHARGE-
ABLE BATTERIES
Your Ni-Cad battery pack recharges
whenever the Handset is returned to
the Base Unit.
IT’S IMPOSSIBLE TO OVER-CHARGE
THE BATTERY PACK
The battery pack can be recharged
many times but if you get a low-battery
signal even after 8 hours of charging in
the Base Unit cradle (or 24 hours in the
Base Unit spare battery charger), the
battery pack(s) should be replaced.
To purchase replacement battery
packs, call VTech at 1-800-595-9511.
