This indicates the display unit is not receiving positioning data from the scanner motor. Check the data cable connections at both the mast unit and the back of the display screen. Inspect the reed switch or optical encoder inside the radar gearbox. 5. Conclusion and Next Steps

The 52-page SMR3700 LCD Color Marine Radar System User Manual is available on the FCC ID database.

After physical installation, the radar requires a mandatory initial setup while in transmission mode.

Since this device is registered for radio use, a high-quality PDF of the User Manual is available via FCCID.io. samyung smr 3700 service manual link

If the radar screen shows no targets while operating in transmission mode (TX), look for a faulty magnetron or a high-voltage power supply failure.

Inspect the inline fuse on the primary 24V DC power cable. Check the internal power supply board (PSU) test points for stable voltage output. Issue 2: Radar Spins But Shows No Targets (Blank Screen)
