UPDATE Option
Update is used to make the data in the lock match the data in the front desk console.
You will update a lock for the following reasons:
• Twice each year to load the daylight savings time information.
• If you change the code of a Programming Card, a Canceling Card, or a
Blocking Card.
• If a change is made to the locking plan such as adding new doors or
new master cards.
Update will also notify a lock if a master card has been changed.
To update the information in a lock, you must first download the data from the front
desk computer to the PP.
After the PP is loaded with data, go to the door that is being updated and follow
these steps:
1. Plug the PP into the lock.
2. Press the ON/CLR key to turn on the PP.
3. Press the MENU key until UPDATE appears.
4. Press the UP or DOWN arrow key to select the desired room. (see note)
