Installation Procedure
1.
To
open
the
transmitter’s
housing,
insert
a
small

seconds.
You
can
terminate
Test
mode
by
closing
the
tamper
switch.
Test
mode
is
automatically
terminated
after
approximately
five
minutes.
Due
to
the
occurrence
of
voltage
delay
in
lithium
batteries
that
have
been
in
storage,
the
batteries
may
initially
appear
to
be
dead.
In
this
case,
leave
the
unit
in
Test
mode
for
a
few
minutes
until
the
battery
voltage
level
is
stabilized.
