Enable Dual Combo Mode on the AMSEC ESL20XL Digital Lock

So here we're going to demonstrate how to enable "Dual Combo Mode". So Dual Combo Mode makes it so that you have to have two people in order to get access to the safe. So the standard Dual Combo Mode has the master user and any of the other 8 users that you programmed in the lock earlier; those two codes have to be used to get into the safe.

To enable it, you're going to press C, #, 30, #, then our Master Code 6-5-4-3-2-1-#, then 1 for enable and then #. So now dual combo mode is enabled. So let's test it. So we're going to do our master code first C-6-5-4-3-2-1-#. It will beep twice, then we're going to put in let's say user # 8. So we did our 9-8-7-6-5-4-#. The lock opened so it required both combinations to get into the safe.
