Battery Charger

The Battery Charger provides power to the 750
operation. It also incorporates a Battery Test Circuit that allows the user to check the charge
on the Battery. Using the 'BATTERY TEST' Button and reading the five (5) multi-colored Battery
Status Indicators, a user can determine the state of the Battery, from 'LOW' to '100%'. To
determine true Battery power level, either disconnect the Power Adapter or place the Charger
switch in 'OFF', otherwise charging voltage will be displayed. Be cautious of leaving the Battery
in an automobile exposed to extreme heat or cold. In these situations take the 750
home or office when not in use. Extreme temperature may cause the Battery to fail.
Battery charge time varies with age, initial battery power, and temperature and can take up to
12 hours from fully depleted to '100% charge. Operating the750
