Battery Charger

Install the battery charger and begin charging the batteries before you install any other components.
Install the battery charger in a clean, dry environment. An office location is best.
The battery charger may be placed on a flat surface such as a table, desk, etc., or it can be fastened to a wall using
the optional wall–mount kit.
Plug the power supply transformer into a 120–Volt wall outlet and then plug the transformer cord into the
connector in the end of the battery charger. The three green lights on the battery charger will turn on.
To charge a battery, plug it into the charger as shown in Figure 2. Observe the charging status indicator next to
the battery:
•
The indicator lights RED to indicate the battery is charging.
•
The indicator lights GREEN to indicate the battery is fully charged.
•
The indicator lights ORANGE to indicate the battery is defective.
Discharged batteries require 1–1/2 to 2 hours to charge.
When the battery voltage becomes too low, a short, low volume tone, occurring at seven–second intervals is
heard in the headset. This repeating tone continues for two minutes. After the two–minute interval, the headset
automatically turns off to prevent battery damage.
