California Energy Commission battery charging testing
instructions
This wireless 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.
If you have registered the wireless headset to the
VH6220/VH6221
headset base, below are
the testing instructions.
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 the 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 blue
PHONE
light on the headset base 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
LED light flashes slowly in red and blue.
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.
If you have registered the wireless headset to a compatible VTech 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 wireless headset to a telephone base that does not have CEC
battery charging testing mode, all telephone functions on the wireless headset, except
battery charging, will be disabled.
