6.7 Special Function
6.7.1 Keypad Lock
In normal status of the unit, press and hold
▲+▼
for 5 seconds. The LOCK icon is
displayed on the controller and all buttons become unavailable. The LOCK icon blinks
when any button is pressed. To cancel the Keypad lock function, press and hold
▲+▼
for 5 seconds again. Then the LOCK icon disappears.
If the unit is faulty, the lock function becomes invalid and all buttons are available
again. The Keypad lock function will resume after the error is rectified. In addition, the
lock status before power failure is memorized.
