Initial Operating Instructions
▶
Each lock is shipped from the factory in Shelved Mode, operating on a standard
combination (50-25-50). The “one time only” combination does not function when the
lock is in this condition. The correct opening procedure for a new lock is :
▪
Turn the Dial left (CCW) until the letters “EC” (Enter Combination) appear on the
LCD
▪
Enter the factory combination of 50-25-50 by sequentially pressing those six buttons.
The LCD will display these number as they are entered.
▪
When the combination has been correctly entered, the LCD will read :OPr” meaning
“Open right.”
▪
Turn the Dial right (CW) until it stops. The lock’s bolt is now retracted and the lock is
open.
▪
Turning the Dial left (CCW) will extend the lock’s bolt
Try this several times until you are comfortable with the operation of the lock.
