Stealth Mode –Silent Operation
The ESL5 and ESL5LP can be set for Silent (Stealth) Mode, such that the Beeper does not make any noise during normal operation.
To turn Stealth Mode ON (silent) or OFF (beeping):
ON (silent): Press C-# (short warble tone), then 8-0-# (short warble), then 1-# (long warble).
OFF (beeps): Press C-# (short warble tone), then 8-0-# (short warble), then 0-# (long warble).
Note that the beeper will still sound during combination changes and programming. It is only silent during normal opening operations.
