KEYPAD SECURITY
The keypad can be “locked,” so that no new parameters or commands can
be entered via the keyboard, thereby preventing unauthorized cancellation or
adjustment.
To activate the security feature, press and hold the numeral 7 key on power
up. When the keypad is secured in this manner, any attempt to change or
enter parameters will result in the following message being displayed on the
LCD screen:
KEYBOARD LOCKED!
