AUTOMATIC POWER DOWN
The Automatic Power Down feature of the PRC 2000 system is a safety feature which removes power from
all channels 90 minutes after all Active Channels have entered the Temperature Setback Mode. This
feature is not programmable and is automatically enabled when all Active Channels are in the Temperature
Setback Mode.
OPERATION
When all Active Channels have entered Automatic Temperature Setback Mode, a 90 minute timer within
the system circuitry will start running.
1. If the system has no Active Channels (no connected handpieces), Automatic Shutdown will not
occur.
2. If any key is pressed during the 90 minute time period, the timer is reset. Timer will not start
timing out again until all Active Channels are in Temperature Setback Mode.
3. During the last minute before the 90 minutes expire, an audible tone will occur every 4 seconds
to alert the operator.
4. At the end of the 90 minute period, the system will enter the Power Down Mode. Power is
removed from all channels, all Channel LEDs will stop flashing and the Digital Readout will
display a flashing “OFF”.
EXITING POWER DOWN MODE
Power Down can be exited with all channels returning to normal operation by pressing any key or by
turning the
POWER Switch OFF (“0”) and then back ON (“1”).
