Basic Operation

Operation

1. Ensure the Set-Up procedure has been performed. Check for the following:
Handpiece connection to the power source.
Appropriate Tip is installed in handpiece.
Power cord is connected to both an appropriate AC supply and the unit.
2. Turn the Power Switch On ("I").
3. After a brief start-up sequence, the Set Temperature will be displayed.
4. Adjust the tip temperature by pressing and holding Scroll Up ( ) Key or Scroll Down ( ) key. Observe
the display as the Set Temperature increases first in increments of 1° and then in increments of 10°.
When the desired temperature is reached, release the key.
5. NOTE: The Set Temperature can be adjusted only within the defined temperature limits. If the upper
limit has been reached, the display will read "HiL"; if the lower limit is reached, the display will read
"OFF". Temperature limits can be adjusted in the Set-Up menu.

LED Display

The LED Display provides a 3-digit display of information. The display will show different things such as:
1. "888" on initial power up to ensure that all sections of the display are working.
2. The software version of the installed microprocessor (e.g., "1-9") for 2 seconds after the "888" is
displayed.
3. Actual temperature of the connected handpiece, during normal operation.
4. The displayed temperature will begin blinking (the indicator LED will also turn Amber) when the unit has
gone into Temperature SetBack.
5. "OFF" with stable display when the temperature set point has been adjusted beyond the Lower
Temperature Limit.
6. "OFF" with blinking display when the unit has entered AutoOff mode. Refer to page 7 for more
information.
Error messages "OSE" or "OCE" will appear if a system fault is detected. Refer to the "Corrective
Maintenance" portion of this manual.

Digital Control Indicator LED

The colored LED on the power source front panel indicates when the handpiece is
heating, has reached the set temperature, or if a fault has occurred.
LED Full On Red – A fault has occurred such as nothing is plugged into the
Power Receptacle on the front of the unit or the Heater Element of the connected
