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.

Before inserting the RECEIVER OR TRANSMITTER into the charger, be sure each unit has rechargeable NiMH batteries
installed. Check that the Alkaline/NiMH battery switch in the battery compartment of the receiver/transmitter is set to NiMH
(Figure 2).

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.

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 1).
The CHG 3512 will power on and run a self-test for 20 seconds, stepping through each bay lighting each LED indicator.

2. Insert the receiver or transmitter into the charging slot as illustrated in figure 1 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 1).
The red LED will blink slowly when the batteries are fully charged (indicates the charger is in maintain charge mode).

If the red LED indicator blinks at a fast rate (4 times per second), the batteries in that bay are very low, or a bad cell is present.
The CHG 3512 will attempt to condition the batteries to bring them up to a safe charging level. If successful, the LED indicator will
change from a fast blinking LED to a steady on, and the normal 16 hour charge time will begin. If unsuccessful, and the charging
LED indicator light continues to fast blink after 3 hours, one or both batteries in that bay are bad, and need to be replaced.

• You may charge up to 12 body-pack units per CHG 3512 charger.

• It will take approximately 16 hours to fully charge the batteries when using the Williams AV rechargeable NiMH battery, BAT

026-2.
