9. During a 10-second period following the initial beep, the lock will perform a battery check. You will hear another single beep
if the 10-second battery check is successful. It is recommended that you wait for this beep before installing the cover onto the
lock. If the lock determines that one or both batteries are not fresh or that they are installed incorrectly, there will be a distinct
low battery signal following the battery check period. The signal consists of ten quick beeps...pause...ten quick beeps...pause...
ten quick beeps. You should then remove both batteries for at least one minute, then re-install them beginning with step 6.
If you still do not hear the battery confirmation beep at the end of the ten-second battery check or if you hear the low battery
signal, replace both batteries with new, fresh ones. If the lock is put into service without confirmation of good batteries and is
subsequently dialed open, it will immediately go into the Lock Open Latch state, forcing you to install fresh batteries.
10. Re-install the lock cover using both cover screws. The longer cover screw goes in the screw hole closest to the change key
receptacle, as indicated on the lock cover label.
Note: This is a great time to employ the Dial Calibration and Battery Condition Check procedures found on page 5.
11. WITH THE CONTAINER DOOR OR DRAWER OPEN, verify that the operating combination(s) can indeed be used to open the lock.
Check proper operation of the combination(s) a minimum of three times before locking the container door or drawer.
