California Energy Commission battery charging
testing instructions
This telephone is set up to comply with the energy-conserving standards
right out of the box. These instructions are intended for California
Energy Commission (CEC) compliance testing only. When the CEC
battery charging testing mode is activated, all telephone functions,
except battery charging, will be disabled.
To activate the CEC battery charging testing mode:
Unplug the telephone base power adapter from the power outlet.
Make sure all speakerphones are plugged with charged batteries
before proceeding.
While you press and hold /HANDSET LOCATOR, HOLD, or
/FIND HANDSET, plug the telephone base power adapter back to
the power outlet.
After about 20 seconds, when the IN USE light starts flashing or the
telephone base shows Deregister all devices?, release /HANDSET
LOCATOR, HOLD, or /FIND HANDSET, and then immediately press
the button again.
When the speakerphone successfully enters the CEC battery
charging testing mode, the voice prompt "Not registered" plays
once upon every key press.
When the speakerphone fails to enter this mode, repeat Step 1
through Step 3 above.
To deactivate the CEC battery charging testing mode:
Unplug the telephone base power adapter from the power outlet,
then plug it back in. The telephone base is powered up as normal.
Register your speakerphone(s) back to the telephone base. See pages
5-7 for speakerphone registration instructions.
NOTE: For users of AT&T business phones, refer to the user's manual of
your respective model for deregistration instructions for activating the CEC
battery charging testing mode.
