show "Lo" and the stored limit. Choose one of the following: 

 

Press and release the Program Key ( ) to keep the stored Low Temperature Limit. 

 

Adjust the stored Lo Temperature Limit using the keypad. (

 

Press and release the Program Key ( ) to proceed to the next step. 

 

The full allowable temperature range of the ST35 is between 38°C (100°F) and 482°C (900°F).  The Low 
Temperature Limit cannot be adjusted higher than the High Temperature Limit.  These limits control how high or 
low the Set Temperature can be adjusted to during normal operation. 

 

Automatic Setback Timer 

 
To preserve tip life and save energy, the system can automatically adjust the tip temperature to 177°C (350°F) 
after a selectable period of inactivity (factory setting of 30 minutes). There are 3 ways to exit Temperature 
Setback; pressing the Scroll Up or Scroll Down keys (

), flipping the power switch off then on again, or 

holding the tip against a damp sponge.  Upon exit of the Temperature Setback, the unit will resume normal 
operations and the handpiece heat back up to the Set Temperature. 

 

7.  The display now shows the stored Automatic Setback time as "S-X" (x=0 thru 9). 

Time is shown as tens of minutes (e.g., "S-3" equals 30 minutes). A display of "S-0" 
indicates that Setback is disabled. Choose one of the following: 

 

Press and release the Program Key ( ) to keep the currently stored 
Temperature Setback time. 

 

Adjust the stored Temperature Setback value using keypad. (

 

Press and release the Program Key ( ) to proceed to the next step. 

 

AutoOff 

 
What is AutoOff?  When enabled, the AutoOff safety feature turns off the power to the handpiece after a pre-
selected time (between 10- 90 minutes) from the system entering Temperature Setback. When the system has 
entered Temperature Setback, a timer within the system circuitry will start running. 
 
If any key is pressed during the selected time out period, the AutoOff and Setback timers are reset. The system 
will return to normal operation. At the end of the time out period, the system will enter Auto Off. Power is turned 
off to the heater and the display will show a flashing “OFF”.  Exiting Auto Off: Auto Off can be exited; returning to 
normal operation by pressing and releasing a Key (any of the 3 keys 

), or by turning the Power Switch 

OFF (“0”) and then back ON (“1”). 

 

8.  The display now shows the stored Auto Off time as "AOx" (x=0 thru 9). Time is 

shown as tens of minutes (e.g., "AO8" equals 80 minutes). A display of "AO0" 
indicates that Auto Off is disabled. Choose one of the following:  

 

Press and release the Program Key ( ) to keep the currently stored Auto 
Off time. 

 

Adjust the Auto Off value using the keypad. (
