NH-2700CE 4. Operating Instructions
4 - 14
6. Turn the dial a minimum of one complete rotation to the left (counter clockwise) to extent the bolt.
NOTE:
After opening and closing any lock, you should always check to ensure that the lock is
physically relocked (i.e., bolt fully extended and locked in place) by turning the dial to the right. If the
bolt does not retract, you can be assured the lock is secured.
Helpful Hint:
At any point while entering the combination during an opening sequence, if you notice
that an incorrect number was pressed on the keypad, you may clear the entire operation and start
again by pressing the star ( * ) key. This allows you to return to the EC prompt without getting a wrong
try error (lightning bolt).
Caution - Lock Out (LCO):
When the combination is incorrectly entered, a lightning bolt error will
flash on the display (with no other numbers following it). To clear this error and start again, press and
hold the star ( * ) key. Even in Shelved Mode, it is important to avoid getting 5 wrong combination
attempts in a row without a successful opening in between because the lock will be put into Lock-Out
condition, displaying, "LCO." Clearing the LCO condition in Shelved Mode requires waiting 5 minutes
and then entering the correct combination.
