Charging the LightMic

The rechargeable NiMH batteries must be fully charged before regular classroom operations.

1.Ensure the LightMic is turned OFF. The LES 780iR must be connected to AC power in order to charge the LightMic.

2.The LightMic’s rechargeable batteries are factory installed. Plug one end of the charging cable firmly into the jack labeled CHARGER on the side of the LightMic. Connect the other end of the charging cable to one of the MIC CHARGE jacks on the back of the LES 780iR.

3.The triangle-shaped light on the front of the LightMic transmitter glows green when the cable is connected and charging correctly. The light goes out when fully charged.

4.The batteries will fully charge in 8 to 12 hours.

5.It is best to leave the LightMic charging until used, since the batteries slowly lose their charge when not in use.

However, do not leave the LightMic plugged into the charger for more than 10 days, as it will significantly shorten battery life.

6.Once the batteries are charged, remove the charging cable from the LightMic.

7.NiMH batteries will maintain their charge for a full day of normal classroom use.

8.With proper care, NiMH batteries will provide service for at least one year. If battery or charging problems occur, contact LightSPEED Service at 800.732.8999.

[ caution! ]

Do not attempt to charge alkaline batteries̶they can overheat and expand, creating a significant hazard and damaging the LightMic.
