USER GUIDE
使用说明
Note: The first 5 minutes with power is the stand-
by time for adjusting sensing distance. Persons or
subjects should avoid standing before the sensor.
The sensor will not flush during this time.
注意：刚通电5分钟内为自动调节感应范围的待机状
态， 感应器前方应避免有人站立或有其它物体，
在该时间内感应器不冲水。
Working Status
Before powering the system on, clear the unwanted
objects in front of the sensor window lest shortening
the sensing distance.
工作状态
此前务必清理感应冲洗器感应窗口前的杂物， 以免
影响自动调距， 导致感应距离的缩短。
工作状态的设定

工作状态为二段式冲洗状态。
2. K-8872T-2W-**
0. 5L和1L可调式冲洗模式切换
出厂默认为0.5L模式，在电控盒初始上电后5分钟内，
可以通过磁棒靠近感应窗口进行0. 5L和1. 0L 的冲
洗切换， 当磁棒贴近电控盒5秒后， 电磁阀快速开关
阀一次， 同时指示灯闪两次， 表示由 0. 5L切换成1L;
如果要从1L切换成 0. 5L, 必须放电后重新上电5 分
钟内进行切换， 当磁棒贴近电控盒5秒后，电磁阀快
速开关阀一次，同时指示灯闪一次，表示由1L切换成
0.5L 。切换新的冲洗模式可以掉电后保存。
注意: 检测时间为5秒， 当卫生间狭小时，为防止误动
作， 本产品将自动把检测时间由5秒变成8秒。
Set Working Status
1. K-8872T-2-**
The working status is set as dual-flush.
2. K-8872T-2W-**
0.5L&1L flush mode change
The default flush mode of sensor is 0.5 L, you can
switch to the 1L flush mode with flushing control
stick. Operate as follow: After initial power on,
during the first 5 minutes, you can switch the flush
mode by putting the flushing control stick near the
right part of the sensor lens. When the flushing con-
trol stick is near the right part of the sensor lens for
5 seconds. There will be one quick rinse and the
indicator light flashes twice after you complete the
1L flush mode setting. If you need to reset the 0.5
L flush mode, you can cut off the power completely
and restart the sensor, during the first 5 minutes,
you can switch the flush mode by putting the flush-
ing control stick near the right part of the sensor
lens. When the flushing control stick is near the
right part of the sensor lens for 5 seconds. There
will be one quick rinse and the indicator light flash-
es once after you complete the 0.5 L flush mode
setting.
Note: The diction time is set as 5s to avoid
improper function in narrow toilets, the detection
time is automatically set from 5s to 8s.
Sensing Distance
During the first 5 minutes, when powered on, the
system is in the phase of automatic regulation, and
no operation is required.
