1.3.3 Battery Charging
Charge up to four batteries while you are installing the other equipment. Charging
time is about 2.5 hours. When the batteries are fully charged, install them in the
headset as shown in section 1.2.3.
Procedure:
Insert batteries in the charging ports for charging. The batteries can only go into
the charging ports one way. If they do not go in easily, turn them around. DO NOT
force them. Push each battery down into a port until it snaps in place, to be sure it
makes full contact.
Battery Status Lights:
The battery status lights indicate the charging status, as shown on the battery
status guide at the bottom of the battery charger front panel.
 A YELLOW LIGHT stays on steady next to each charging port while the port is empty.
 Insert a battery in one of the four charging ports until it clicks in place.
 A RED LIGHT will stay on next to a battery while it is charging.
 A GREEN LIGHT will go on next to a battery when it is fully charged.
 If a YELLOW LIGHT is on next to a battery in a charging port, it means the charge
failed. If this happens: (1) Be sure the battery is pushed all the way into the port until
it snaps into place to make contact. (2) Try charging it in a different port. If it charges
this time, the first charging port may be defective. If the battery does not charge in the
second port, replace it with another battery.
 Store up to four fully charged batteries in the storage ports.
