2.9 — Low Battery Indicator
If you enter a correct User Code and hear 5 double-beeps when the lock opens, the batteries
are low . Change the batteries .
If the batteries are so low the lock can't work properly, the lock beeps 20 times when a User
code is entered . The lock will not open . Change the batteries right away and re-enter a User code
to open the lock .
The 9V batteries are located behind the keypad .
2.10 — Changing the Batteries
The lock will not lose any codes or program settings while you replace the batteries .
Your lock uses two 9-volt alkaline batteries . We recommend Duracell
®
alkaline batteries .
To change the batteries, carefully remove the
keypad housing by lifting the bottom edge (closest to
the S&G logo) and easing it off the base . Detach both
batteries from the terminals . Insert the new batteries,
supporting the top of each battery holder with your
other hand to prevent bending or breaking the holder .
2.11 — iButton Touch Key
The touch key allows you to transfer the audit trail from the lock to your computer . The audit
trail is a time and date stamped record of all lock activity . The touch key is also used in the
authorization of Service Mode Users at the lock .
The Sargent & Greenleaf Lock Management
System software or S&G’s Audit Manager software
must be installed on your computer before you can
upload and use the audit trail information stored in
your lock . For more instructions on downloading the
audit trail see Section 3 .2 .
