• The C960 charger automatically discharges cells that are placed in it. However the left two slots can only
remove 10% of a full charge and the right hand slot can only remove 20% of a full charge. Therefore, as
often as is practical, leave the batteries in the headset/beltpack until the low battery alert sounds.
• An improved C960 Outer Case is now available from spare parts. The part number has not changed (78-
8095-0525-4). It has threaded brass inserts for the case screws and it includes the screws. Avoid over-
tightening the screws to prevent the screw ends from protruding through the Inner Case.
To prevent the plastite screws from loosening on the old-style case place a VERY small drop of white wood
glue on the screw threads before tightening.
