Charger only
CHG 3512 PRO: Charger in case
WARNING: DO NOT ATTEMPT TO CHARGE NON-RECHARGEABLE BATTERIES! NON-
RECHARGEABLE BATTERIES, SUCH AS ALKALINE AND CARBON ZINC, MAY HEAT UP AND
BURST, CAUSING POSSIBLE INJURY AND DAMAGE TO THE EQUIPMENT.
MODEL CHG 3512 PRO: DO NOT CLOSE THE CASE WHILE THE RECEIVER OR TRANSMITTER UNITS
ARE CHARGING! THE CASE MUST REMAIN OPEN TO ENSURE PROPER VENTILATION WHILE
CHARGING.
BEFORE INSERTING THE RECEIVER OR TRANSMITTER INTO THE CHARGER, BE SURE EACH UNIT
HAS NiMH BATTERIES INSTALLED. ALSO, CHECK TO MAKE SURE THE SWITCH SETTING IN THE
RECEIVER OR TRANSMITTER BATTERY COMPARTMENT INDICATES THE “NiMH” SETTING.
Instructions:
1.) Plug the TFP 037 power supply into the AC wall outlet. Plug the power connector into the rear
of the CHG 3512 unit (Figure B).
2.) Insert the receiver or transmitter into the charging slot as illustrated in Figure A above. The unit(s)
must be placed in the charger facing forward to make contact with charger contacts. A red LED
indicator will illuminate when charging has started (Figure A). The red LED will blink when the batter
ies are fully charged (indicates the charger is in maintain charge mode).
• You may charge up to 12 receiver units per CHG 3512 charger.
• It will take approximately 16 hours to fully charge the batteries.
Note: It is safe to leave the receiver/transmitter units in the charger, even after the batteries are fully
charged. The charger will switch to pulse/maintain mode to maintain full battery potential.
