5.1 באַטאַרייע ייַנמאָנטירונג
Before installation, insert the required batteries into both the receiver and transmitter units. Ensure correct polarity.

בילד: דערציען view of the receiver unit, showing the battery compartment with the cover removed. This is where the receiver unit's batteries are inserted.
5.2 Transmitter Unit Installation
The transmitter unit is installed at the top of your water tank. Follow these guidelines for optimal performance:
- אַנטענע: Ensure the antenna is positioned for clear signal transmission.
- Balance Bubble: Use the integrated balance bubble to ensure the transmitter is level for accurate readings.
- מאָונטינג: Secure the transmitter using screws through the designated bracket.
- סענסאָר אָרט: The ultrasonic sensor should have a clear path to the water surface. Ensure there is a minimum air gap of 0.5 meters (H1 height) between the sensor and the maximum water level.
- Tank Opening: The tank opening for the sensor should be at least 20cm in diameter (Ø > 20CM) to prevent interference from tank walls.

בילד: A detailed diagram illustrating the components of the transmitter unit (antenna, balance bubble, sensor), a setup sketch for proper installation on a tank, and visual examples of incorrect installation methods to avoid.
5.3 Receiver Unit Placement
The receiver unit can be placed indoors. It features a stand for desktop use or can be mounted on a wall using the integrated hooks. Position it in a location where the signal from the transmitter is strong and clear.
