Getting Started
Setup
Charging of the Handset Batteries
The handset of your cordless telephone is powered by
rechargeable batteries. It charges automatically whenever the handset is in its charger or base unit.
You should charge the batteries for 10-12 hours when
you first receive your phone. You will know the batter-
ies needs charging when:
• The low battery message is displayed:
• The handset seems completely dead, the LCD is completely clear and does not
activate when you press the keys.
• If the phone will not be used for a long period of time, remove the batteries to prevent
possible leakage.
NOTE: When in LOW BATTERY mode, the keypad sounds, backlighting and speak-
erphone features will not work. When your battery has been charged, your features will
return to their normal function.
IMPORTANT:
1. Do not dispose of batteries in a fire, they might explode.
2. Do not open or mutilate the batteries. Toxic substances may be released, causing
harm to eyes or skin.
3. Exercise care in handling batteries in order to prevent an accidental short of the
charge contacts, potentially causing the batteries to overheat.
Installation of Batteries
1. Place the new batteries in the handset
with the positive and negative poles
aligned in the battery compartment.
2. Replace the battery cover by sliding it
upwards.
3. If the new batteries are not already
charged, place the handset in its base
unit or charger and allow it to charge for
10-12 hours. After that, be sure to place
the handset in its base when not in use
to insure maximum daily performance..
WARNING: Alkaline batteries must NOT
be used in your mi 6823 cordless telephone. Use only the batteries that came
with your phone, or contact VTech Customer Service (contact information on
page 2) to order additional batteries.
4. Do not dispose of these batteries into household garbage, they should be properly
recycled.
5. Do not charge the batteries with other electrical devices.
