Pairing Sensor
The KATVR-Central and the KATVR-Back Sensor can only be used after being paired, and the two KATVR-Foot Sensor can
only be used after being paired with the wireless receiver.
Pairing of KATVR-Central and KATVR-Back Sensor
The KATVR-Central and the KATVR-Back Sensor are paired when the six-digit dialers are dialed to the same position.
Similarly, dialing the dialers to different positions can prevent communication interference for the KATVR-Central and
the KATVR-Back Sensor between different equipment. Please note the positions of ON and the digits 1-6 as shown in t
he figure, which are wrong:
30 Starting Installation
Caution
Within the same place, all the KATVR-Central dialing values should differ from each other, and so
it is for the KATVR-Back Sensor dialing values. Otherwise, the KATVR-Central of one piece of
equipment might connect to the KATVR-Back Sensor of another. Within the same place, all the
wireless receiver dialing values should differ from each other, and so it is for the KATVR-Foot
Sensor dialing values. Otherwise, the KATVR-Foot Sensor of one piece of equipment might
connect to the wireless receiver of another.
