APPENDIX I
IDENTIFYING AND TESTING THE POWER FAILURE MODEL
Power Failure model Liteboxes are essentially the same as conventional Liteboxes with the
exception of the PC board. Follow the standard instructions contained in this manual to
identify and test the Power Failure model.
Identifying The Power Failure Model
The label located above the LED’s on the Litebox indicates what type of unit it is. The power
failure version is marked with the words “power failure” above the serial number on the label. The
power failure model Litebox printed circuit board is different from that of the non-power failure
Litebox. The power failure circuit board has most component positions filled (some examples
are: Q5, C4, Q4, CR10 and R14-R17).
Testing a Power Failure Litebox
1. First remove the Litebox from its charging rack and verify that the lamp is working.
2. If the lamp works switch the Litebox off.
3. Connect a wall charger directly (no charge rack) to the Litebox.
a. If the charger is not plugged into a wall outlet the Litebox should turn on with full intensity.
b. Plug the wall charger into a working wall outlet; the Litebox should turn off.
4. An optional method of testing the power failure Litebox is to use a piece of wire (or needle
nose pliers) to short the contacts on the power input connector. When the contacts are
shorted the power failure Litebox should turn on.
If the Power Failure model fails to perform as indicated above; the printed circuit board will need
to be replaced. Refer to Section IV.
