1.5 Tamper Shutdown:
The programmable tamper shutdown feature allows the master user to select the number
of wrong code attempts needed to lock out all users temporarily, and the length of time that
all access code are disabled. This feature prevents random guessing of codes.
All user codes are locked out until the end of the tamper shutdown period, or until the tamper
shutdown is cleared by a manager or master code (see section 2.7, "Clearing a Tamper
Shutdown"). Entering further invalid codes during a tamper shutdown re-initializes the timer,
beginning another full shutdown period.
A person can exit the room from inside at any time by turning the inside handle.

1.6 Mechanical Key Override:
In an emergency, or if the batteries are dead, the override key can be used to open the door.
Insert the key and turn it 90º, then turn the lever. Note that turning the key alone does not
retract the latch. Do not force the key. If the key is turned but the lever will not retract the latch,
turn the key in the opposite direction.
WARNING: Never turn the key and the lever at the same time. Turn the key a full 90
º
and then turn the lever. Never force the key.
