Temperature Setback Mode
To preserve tip life and save energy, the TW 50 system can be programmed to automatically set back its
Tip Temperature to 177°C (350°F) after a selected period of handpiece inactivity. The LED Display will
blink “177” or “350” depending on the selected temperature scale. As received from the factory, this
feature is enabled. Refer to number 9 in the “Programming Your System” section of this manual to
disable or adjust the time-out period of this feature. The operator can also force the system into
Temperature Setback.
Activating Temperature Setback:
There are two ways to activate the Temperature Setback feature.
1. AUTOMATIC ACTIVATION: The system can be programmed so that this feature will
automatically activate after a pre-selected period (10-90 minutes) of handpiece inactivity.
See the “Programming Your System” section for details on programming this feature.
2. MANUAL ACTIVATION: The operator can manually force the system into Temperature
Setback by performing the following procedure.
a. Press and hold the Scroll Down

Using the TW 50 Calibration Feature
The new TW 50 systems feature an all-new calibration procedure. The system is calibrated so the
display matches the measured tip temperature using your own testing method. This new PACE feature
allows any type of temperature verification device to be utilized to complete the simple procedure.
Calibration can be completed, as often as you like, in order to meet your own internal specifications.
