CHMASK SETUP (optional)

For AU915/US915 band devices only.
Follow the guide in step 1: 

“Hold the magnet against the device for at least 1 
second while the water is running.”

The ChMask is applied with holding the 
magnet for different time.

• For default 64 channels setup: Follow 
the guide normally. 
• For pre selecting an 8 channel range, 
keep holding the magnet for 5 seconds 
(the light flashes red while holding). 
After that the light will flash blue every 2 
seconds, accompanied with red flashes 
that flash as many times, as the blue 
light has flashed. The blue light indicates 
the channel range. After getting to the 
desired range, the magnet needs to be 
released after the blue light flash.

Channel ranges are as follows:
 

0-7 : blue has flashed 1 time

 

8-15 : blue has flash 2 times

 

16-23 : blue has flash 3 times

 

24-31 : blue has flash 4 times

 

32-39 : blue has flash 5 times

 

40-47 : blue has flash 6 times

 

48-55 : blue has flash 7 times

• The device is not allowed in the net-
work and it must be registered with the 
service provider.
The necessary data is on a separate 
sticker in the package (DevEUI, AppEUI, 
AppKey). Once the device is registered 
repeat the switching on procedure de-
scribed under point 2.
