periods of use, 1-2 hours, will shorten battery life (NiMH batteries do not have this charac-

teristic). Rechargeable batteries will need to be replaced after 1-2 years of use. Do not

dispose of batteries in fire. Do not open batteries, there are toxic chemicals inside.

USING THE OPTIONAL CHG 1600 BATTERY CHARGER

With AC power connected, the CHG 1600 Multiple Charger operates in a “trickle charge”

mode. Units can be left on trickle charge indefinitely without risk. Pressing the Overnight

Charge button switches the charger to a higher-rate, overnight charge mode on a 15 hour

timer. After 15 hours, the “Complete / Maintain” light will come on and the CHG 1600

reverts to trickle mode. Any time the button is pressed, the 15 hour timed charge begins

again. The CHG 1600 Charger does not monitor individual unit battery state.

Charging Instructions

Step 1: Plug the power supply into an AC wall outlet. Plug the power connector into the

jack on the right side of the CHG 1600’s control panel.

Step 2: Make sure the units you will charge are turned OFF. DO NOT attempt to charge

non-rechargeable batteries.

Step 3: Place the units in the slots so that the charging pins and the unit’s side contacts are

coupled. The “CHG” indicator next to the unit will be dimly lit.

Step 4: When all units are in place, press the red button on the CHG 1600’s control panel.

The red “Overnight Charge” indicator on the CHG 1600’s control panel will light

during charging, and the “CHG” indicators next to each unit will be brightly lit.

Step 5: The CHG 1600 will charge the units for approximately 15 hours, then

automatically resume a trickle charge. The “Complete/Maintain” indicator will

come on.

Units may be fully charged before the green “Complete/Maintain” indicator is lit. Units may

remain in the CHG 1600 Multiple Charger for more than 15 hours without harm. Williams

Sound rechargeable AA batteries can be charged on a daily or less frequent basis.
