ACTIVATION OF LOCKOUT FEATURE
1. Adjust the temperature set knob to the desired tip temperature.
2. Apply the Lockout Pencil to the ESD symbol on the front panel until the LED starts slowly (5 Hz) blinking Red.
Remove the Lockout Pencil within 2.5 seconds and the temperature setting will be Locked in. The indicator LED
will be Red and turning the temperature set knob will have no effect on the tip temperature.
3. Reverse the lockout by applying the Lockout Pencil to the ESD symbol until the LED is slowly blinking Red.
Remove the Lockout Pencil within 2.5 seconds and the temperature set knob will function normally and the
indicator LED will be Green.
Note:
If the Temperature Set Knob has been adjusted during the Locked Mode, the station will control to the new
set point, once the Lockout feature has been disabled.
