LightSpeed Technologies 780iR - Manual (Page 12)

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