5.1
Check the following:
a)
Door latches move freely;
b)
Cable is properly routed such that it will not be pinched,
stretched or damaged when the Lockbox door is closed;
c)
Fastener bolt is tightened securely;
d)
Lockbox is not twisted
WARNING: Do not close the Lockbox door until latches are
extended (and so proving they move freely.) Failure to do so
may render the unit inoperable and require unit destruction!
Lockboxes with mechanical door stops
Reinstall the door rotation limiter utilizing the two screws as
shown.
5.2
To test the system, on the keypad of the lockbox, hold the
ENT key down until you hear a beep from the lockbox and
the keypad illuminates. On the keypad, press FUNC 3 ENT.
The latches should retract slightly the first time and then
return to the extended position. Test the unit with the door
in the open position until you are satisfied the latching
system is functioning properly.
