2 USAGE WARNINGS
Give each alarm the most attention possible.
Never assume that the reason for the alarm is accidental until that has been established definitively.
▪
Ensure that the monitoring area is free of any unnecessary movements, (people, machines, etc.) in order to avoid false
movement detections.
▪
In the case where it is no longer possible to measure the distance when a structure is under surveillance (in case of fog,
for example), the alarm will sound to alert the user.
▪
The device is designed to filter out short-term obstructions to the laser beam (passing people, birds, etc.).
Longer lasting obstructions will trigger the alarm.
▪
Fog, dust or intense light can influence the device's range. The user must take into account the environmental
conditions and adapt the distance so as to have accurate measurements.
▪
When the temperature is very low (0°C (32°F) or lower), the batteries cannot be used. It is strongly recommended to
use an external power source.
▪
Always make sure to use good-quality lithium, alkaline or rechargeable NiMH batteries.
Never use zinc batteries (zinc-carbon or zinc-chloride).
▪
Do not use a mix of battery types.
▪
When using the mains adapter outside, always protect it from rain and moisture.
▪
Always test to see that the device is working correctly before any real use by verifying that the alarm works and the
flashes light up.
▪
The scope is adjusted in a way to make the laser's red dot coincide with the cross-hair at 35 m (114.8ft).
Their alignment differs for distances shorter and longer than 35 m (114.8ft).
▪
To avoid measurement errors, try as much as possible to position the laser beam perpendicular to the targeted surface.
Do not aim at dust-free glass, expanded polystyrene or surfaces that are similarly transparent.
▪
When aiming at highly reflective surfaces, the laser beam can be diverted and measurement errors can occur.
▪
The measurement time can increase when the surfaces are dark or non-reflective.
▪
Wear a protective headset when approaching the laser after the alarm is triggered (105 dB) .
▪
Never look directly into the sun through the scope. That could cause eye injuries.
