OPERATING THE AT10.1

2.3.9. Using the front panel security feature

The AT10.1 charger is shipped with all the front instrument panel keys

enabled. You can disable the following front panel functions:

• Selecting Equalize method

• Changing settings using the EDIT/ENTER key

• Toggling the high dc voltage shutdown feature

To disable the front instrument panel keys, open the AT10.1 door and

locate the small plastic jumper J9 on the right side of the main control

circuit board. See the figure below.

Move the jumper up to the DISABLE position (pins 2 and 3). With this

setting, only the front panel

METER MODE and CHRG MODE keys will

function. All indicators will still work normally. Return the jumper down

to the ENABLE position (pins 1 and 2) to return all front panel key

functionality.
