Magnetic deviation error
On the Furuno PG-500R if the status led blinks quickly what does that mean?
On the Furuno PG-500R if the status led goes off what does that mean?
Other than an EEPROM error or Magnetic deviation error. The appropriate LED blinks. If the CALIB LED blinks then it is a Rate Sensor error. If the TRUE LED blinks cable of the magnetic sensor is cut.
How do you clear the memory on a PG-500R?
- 1. Disconnect the power cable from the
- 2. Reattach the cable while pressing the
- [AUTO] and [ADJ] keys together.
