1. Turn off power by depressing the power switch.
2. Wait approximately two seconds before turning
the power back on.
3. Wait approximately two seconds before turning
the power off.
4. Repeat Steps 2 and 3 for two more on/off cycles.
5. After the three on/off cycles are completed, turn
on power by depressing the power switch on. The
