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:
1. Place all wireless mics (with batteries inserted) into the base unit to make sure they can work
normally with the base unit.
2. Unplug the power cable from the power outlet.
3. While you press and hold
MUTE
ALL
on the base unit, plug the power cable back to the power outlet.
4. After about 20 seconds, when the base unit status indicators start flashing, release
MUTE
ALL
and then
press it again within one second. You hear a confirmation tone.
The process takes up to one minute to complete. When the base unit successfully enters the
CEC battery charging testing mode, the base unit status indicators turn off and all wireless
mics are deregistered. All telephone functions, except battery charging, will be disabled.
If the base unit fails to enter this mode, start again from Step 1.
Note:
The base unit will be powered up as normal if you fail to press
MUTE
ALL
within one second in Step 4.
To deactivate the CEC battery charging testing mode:
1. Unplug the power cable from the power outlet, and then plug it back in. The base unit is powered
up as normal.
2. Register your wireless mics back to the base unit. See page 37 for registration instructions.
