PERATION
4.1 CHARGING THE BATTERY
(NICAD BATTERY OPTION)
If the ATX612 is equipped with a Nicad battery pack, fully
charge the battery pack before use. A universal charging adapter
is included with the unit for charging the ATX612 battery pack.
The battery pack may be charged while attached to the
instrument or when removed to allow round-the-clock operation
of the ATX612 using a spare battery.
The ATX612 is equipped with a nickel-cadmium battery pack
with a built-in “smart” charging system. When plugged into the
charging adapter, the battery will recharge at a high rate until
fully charged and then will reduce to a maintenance trickle
charge rate. The battery will not be damaged if it is left
connected to the charger for extended periods.
