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!
