USING THE CHG 200A BATTERY CHARGER

1. Plug the CHG 200’s power supply into the Power
Input on the charger’s side and a standard AC wall
outlet.
2. Route the power cord around the Cord Hook (see fig-
ure at right). This will minimize strain on the cord and
jack and insure that the power cord is not detached
during charging.
3. Make sure the transmitter or receiver units to be
charged are turned OFF.
4. Place the transmitters/receivers in the slots so that the
CHG 200’s Charging Pins and units’ side panel con-
tacts are coupled. Make sure that the charging contact
holes line up with the charging pins. The
transmitters/receivers should drop easily into the slots.
DO NOT FORCE THEM IN BACKWARDS.
5. The Charging Indicators will light, indicating that
charging is in process. It takes 14–16 hours to fully
charge the batteries. Remove the transmitters or
receivers when charging is completed.
Further Suggestions
• Receivers and transmitters SHOULD NOT be left
charging continuously when not in use. Receivers and
transmitters should always be turned OFF while charg-
ing.
• It’s best to allow the batteries to fully discharge before charging.
• If the batteries are near end of life and the LED turns off while the receiver is operating, this is an
indication to change or recharge your batteries. Approximately one hour of battery life remains.
•Repeatedly charging the batteries after short periods of use (1-2 hours) will shorten battery life.
• Rechargeable batteries will need to be replaced after 1–2 years of use.
