Points to confirm before production so the unit arrives ready to fit.

Confirm model: YS-BR-L (107dB, 127mm) or YS-BR-S (102dB, 105mm)
Confirm the voltage (9-32V wide voltage)
Confirm the wire length (standard 220±15mm bare wire) and connector type (DT / AMP / bare wire)
Confirm whether you need to customize the sound pressure level, appearance installation method or voice prompt content
Confirm quantity, packaging and printing requirements in advance.

Voltage, wiring, sealing and maintenance guidance for the installer.

Before wiring, confirm the voltage and never reverse the polarity.
Install the bell mouth downward to prevent water and mud from blocking the sound hole
The installation surface should be flat, and the screws should be tightened but not over-torqued to avoid deformation of the metal housing
Route the wires securely and avoid being close to high-temperature parts such as the engine
Do not tweet at full power continuously for a long time
Regularly check whether the sound hole is blocked by mud or dirt
