sensor. As the user enters the beam's effective range ( 1-9/16"
～
3- 5/32")
for more than 5 seconds, the output circuit continues in a "hold" mode for
as long as the user remains within the effective range of the sensor.
3. Make sure water supply is turned off before inatallation.
3.Do not directly spray water on or use abrasive/chemicals when
cleaning.Doing so may result in short-circuit or discoloring of
chrome plating.Clean using a damp cloth.
2. When the user steps away from the sensors , the circuit initiates a
flushing cycle to flushes the fixture. The circuit will then automatically
resets for next cycle.
