screw first.

battery’s plastic connector.

with the embossed numbers facing up.

Note: The handset may “beep” when the battery is connected. This is not
an indication that the telephone is ready to use. To obtain optimal perform-

be charged for approximately 15 to 20 hours, without interruption,
before use. To charge the battery, place the handset, keypad down,
in the base unit. Make sure the 

CHARGE

LED on the base lights.

If the LED does not light:

1. Ensure that the AC adapter is plugged in.
2. Ensure that the AC adapter is not plugged into a switched

electrical outlet.

3. Ensure that the handset charging contacts at the bottom of 

the handset are making good contact with the base unit’s 
charging contacts.

CLEANING THE BATTERY CONTACTS

To maintain a good charge, it is important to clean all charging
contacts on the handset and base unit. Use a pencil eraser or
other contact cleaner.

Do not use any liquids or solvents.

BATTERY SAFETY INSTRUCTIONS

1. Use only Teledex-approved battery replacements.
2. Dispose of used batteries according to local codes pertaining

to rechargeable batteries.

3. Do not dispose of batteries in fire, as they may explode
4. Charge the telephone's batteries only while in the telephone 

handset, and only by using the telephone base unit to charge.
Do not attempt to remove the batteries and charge them in 
a separate charging unit.

5. Do not short-circuit the battery pack, as this may cause it to 

explode or catch fire.
