This detector contains an environmental
stabilization circuit which requires
approximately 2 minutes after initial
power-up to warm up. During this time
the detector will not respond to any
movement.
Please wait 2 minutes after initial power-up to
perform any walk tests.
Although generally not required, if
masking is desired, the lens diagram
shows the appropriate areas to be
masked (see shaded area on the
DS940Q lens diagram). Use an
opaque material (such as, electrical
tape) to mask the desired areas.
