. Power on the receiver. After the full display on the screen for 3 seconds, a “BI” sound will be emitted, and “1.00” with a flashing empty tank will be displayed (as shown in Figure ).
Figure Enter the water tank depth setting mode (setting range 0.5~5m/1.64ft~16.4ft). During the setting, short press the “+” key to increase by one, long press the “+” key for continuous increase, short press the “-” key to decrease by one, and long press the “-” key for continuous decrease.

Press the “SET” key again to set the air gap value, initially displaying “0.50” (as shown in Figure ), with a setting range of 0.5~5m/1.64ft~16.4ft. It is recommended to set the air gap value to be 0.5m for optimal monitoring status.
————
Air Gap Height
————
Figure Note: The air gap value is the monitoring distance from the bottom sensor of the transmitter to the highest water surface in the tank, with a minimum of 0.5m. During settings, a short press of the “+” key increases the value by one, while a long press of the “+” key results in continuous increase. Similarly, a short press of the “-” key decreases the value by one, and a long press of the “-” key leads to continuous decrease. Note: If there is no operation in the depth setting mode for more than 15 seconds, it will automatically switch to normal display mode. Note: If the receiver displays “EEr” (as shown in Figure ), it indicates a data setting error, and you need to reset. In the normal mode, simultaneously press and hold the “SET” and “AL” keys for 3 seconds to restart the setup process; the setup steps are the same as described above.

. After completing the above-mentioned steps for the receiver, power on the transmitter.

Upon powering on, the transmitter will send the first signal, and subsequent signal transmissions

will occur every 30 seconds or 180 seconds.

H3: Maximum depth measurable by the transmitter. R: Radius of the tank. Note: The radius R of the water tank will affect depth measurement. Regarding R and H1, refer to Figures and , and pay attention to the following during installation: 1. The distance H2 between the bottom of the transmitter and the highest water surface must
be at least 0.5m (1.64ft). 2. The maximum container depth H1 that the device can measure is 5m (16.4ft). 3. Observe the level on the transmitter to ensure it is installed in a horizontal position with the
bubble centered (as shown in Figure ).

a. The transmitter is not installed in a horizontal position. b. The transmitter is too close to the walls of the water tank. c. There are solid objects in the water tank. d. The bottom of the transmitter is submerged in water (or another liquid ). Note: Under normal operating conditions, the transmitter is designed to effectively protect against splashing rainwater from any direction.

13 Backlight Setting
When the receiver is powered by batteries, a short press on any key will turn on the backlight for 15 seconds. If there is no other key operation, the backlight will automatically turn off. In normal mode, to keep the backlight constantly on, long-press the “+” key for 3 seconds. After hearing a “BI” sound, the backlight will stay on continuously. In normal mode, to turn off the backlight, long-press the “+” key for 3 seconds. After hearing a “BI” sound, the constant backlight will turn off (as shown in Figure )
Long-press the “+” key for 3 seconds to turn on or off the backlight Figure
Notes: when powered by the TYPE-C power cord, the backlight defaults to constant-on, while it defaults to off when powered by batteries. Using the constant backlight mode under battery power will consume more battery. If you want to extend the battery life of the receiver, it is recommended to turn off the backlight when not needed.

14 Time Setting
In normal mode, long-press the “SET” key to set the time. The corresponding setting item will blink during the setting process.

Note: Receiver temperature measurement range: 0~50 , -32~122 Transmitter temperature measurement range: -40~60 , -40~140. When the temperature is below the minimum value, it will display “LL.L”; when it exceeds the maximum temperature value, it will display “HH.H” (as shown in Figure ). High or low temperatures may affect battery performance, and the battery may not provide stable power output, potentially impacting the circuit’s operation.

19 How to Reconnect the Signal
When the transmission signal is lost, the corresponding icon ” ” disappears. The water level and temperature will maintain the values from the last measurement. If there’s no automatic reconnection within 1 hour, the water level value will start to flash. To manually reconnect near the transmitter, press and hold the “TANK” key for 3 seconds in normal mode. The maximum interval between two signal transmissions is 3 minutes, with one transmission every 3 minutes. Note: If multiple connection attempts fail at close range, it is necessary to check whether the transmitter is working properly. You can first replace the battery with a new one and then restart the transmitter. The fastest way to connect the product, in close proximity, the receiver is energized first to set it up, then the transmitter is energized.
