extension monitor in the following locations:
– Places where vibration or any other kind of impact occurs.
– Places where echoing is frequent.
– Places near a high concentration of dust, hydrogen sulphide, ammonia, sulphur, or noxious fumes.

For the doorphone

the doorphone in the following locations:
– Where most of the background is the sky.
– Where the background is a white wall, and direct sunlight will reflect off it.
– Where direct sunlight will shine on the doorphone.

R Do not place the doorphone in locations where echoing occurs, as this will cause the doorphone to

beep frequently.

Only when installation work specified in this guide is properly performed and appropriate water
protection treatment is performed.
