Navnet 1934c Getting power off while transmission

[Niros Fayas]

I am having Navnet 1934c and getting power off while transmission. Some times it happened after 30 min some times it happened after 2hour. What may be a issue? Please help

I would first suspect the boat power (amperage) is dropping to the point the radar doesn't have enough power to operate so the unit shuts down to protect itself. If that isn't it it could be the power board in the display has an issue and overheats at some point and shuts down. If it was the motor start up circuits or the modulator board it would always shut off the instance you go to transmit. I think the largest percentage falls on the boat power system.

Alarm comes "No bearing pulse detected" and getting off

It is normal to see that alarm when the antenna is not spinning and the bearing and heading pulses are not being generated.
