The PIR detector requires 3 size AA batteries. We recommend using
high-quality alkaline batteries to ensure longest possible battery life.
• Remove the battery compartment cover as described on the
previous page.
• Ensure that the 4-way DIP switch settings in the centre battery
compartment reflect the desired operating modes and if neces-
sary, set them as described in section 13 (Individual settings).
• Insert the batteries in the battery compartment observing the
correct polarity (plus/+ and minus/-, see figure on right).
• The battery compartment remains open.

After inserting the batteries, the device needs about 75 seconds before it is
ready for use. Within this time no motions will be detected.
