Temperature Setback Operation
Factory Default
As received from the factory, the system will not go into Automatic Temperature SetBack. To enable this feature,
refer to the "Calibration" portion of this manual.
The Automatic Power Down feature of the MBT 250 systems is a safety feature which removes power from all
channels 90 minutes after all Active Channels have entered the Automatic Temperature Setback Mode. This
feature is not programmable and is automatically activated when the Automatic Temperature Setback feature is
enabled.
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.
3. During the last minute before the 90 minute period expires, 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").
