Sensing distance of my MS 2844-222

[jzh]

HI, my 2844-222 can only sense about 2-3 meters distance. The document said it can reach 40feet. 

Does anyone have the same issue?

thanks

And my old MS 2842-222 can sense about 10 meters.

Have you checked the dip switch for sensitivity?

Jumper 1 – Sensitivity To reduce sensor’s detection range by approximately 33%, use needle-nose pliers to carefully remove Jumper 1 (the left-most jumper) from the single pin it is installed on and reinstall it on both pins. Tap the set button once, wait 10 seconds and activate motion to establish the new setting.

You listed both so it's a bit confusing in the morning before a pot of coffee.
