2.8 – “Press for Capacity” Button and LED Status Indicator
The “Press for Capacity” button indicates the capacity of the power cells without applying ac input power. The
status of the capacity lets the user know if there is enough power to perform another engine start. When the
capacity is low the unit should be connected to ac power to allow it to recharge.
Make sure that you wait at least 2 minutes after ac power is applied, or dc power is extracted from
1.
the unit, before you press the “Press for Capacity” button. This ensures a correct reading.
Without ac power input or dc power output, simply press the “Push to Test” button on the faceplate
2.
and hold for approximately 2 to 3 seconds.
The LED bar graph should light up indicating the status of the power cells.

In addition, the fan(s) should start operating when the button is pressed. If you do not hear the
4.
fan(s) running, stop pressing the button and check for any obstructions.

plugged into aircraft, vehicle or ac power.
