Appendix
California Energy Commission battery charging
testing instructions
This headset 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 headset
functions, except battery charging, will be disabled.
To activate the CEC battery charging testing mode:
1. Unplug the headset base power adapter from the power outlet. Make sure the
headset is plugged with charged battery before proceeding.
2. Press and hold PAIR on the headset base while powering up the base by plugging
in the adapter.
3. After about 20 seconds, when the MUTE light starts flashing, release PAIR and then
press it again within two seconds.
The process takes up to one minute to complete. When the headset
successfully enters the CEC battery charging testing mode, the MUTE light
turns off and the headset ON/OFF light flashes twice every five seconds.
Note: When the headset fails to enter this mode, repeat all the steps mentioned above.
To deactivate the CEC battery charging testing mode:
1. Unplug the headset base power adapter from the power outlet, then plug it back
in. The headset base is powered up as normal.
2. Register the headset back to the headset base. See page 19 for headset
registration instructions.
If you have registered the cordless headset to a compatible AT&T DECT cordless
telephone, please refer to the respective user's manual for the activation and
deactivation of CEC battery charging testing mode.
If you have registered the cordless headset to a telephone base that does not have
CEC battery charging testing mode, your telephone system, including the cordless
headset, will not enter the CEC battery charging testing mode.
