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
56-63 : blue has flash 8 times
