Important: Read the following instructions before using
any of the 3 keys supplied (Shown in Fig. 21)
!
The E-760/770/790 with a recodable cylinder can be operated
with three different keys. The keys are numbered 1, 2 & 3, and
each key is labeled and supplied in a separate plastic bag. It is
very important to use them in order.
* Always read the label instructions on the label
before using a key.
Caution: The use of key #2 automatically cancels the
function of key #1, and the use of key #3 automatically
cancels both keys #1 and #2.
If key #3 is used first, it will immediately make keys #1 and
#2 unusable.
Once a key is cancelled, it can’t be reactivated unless
the cylinder itself is re-pinned.
