What to do if Simrad Marine Equipment loses course and goes into Standby mode?

  Holly AndersonAug 8, 2025
  If your Simrad Marine Equipment suddenly loses course and goes into Standby mode, it could be due to a few reasons. The power might have been interrupted briefly, or the voltage is low, so uprate batteries. It could also be that the cable used to the socket is too small, or that there is an intermittent connection. Check all connections and charge batteries. To resolve this, increase the size of the cable.

Why is Simrad TP22 Marine Equipment helm hard over with continuous alarm?

  Angela AndersonAug 15, 2025
  If the helm is hard over and the alarm is continuously on for your Simrad Marine Equipment, it means that the steerage way is insufficient to control the course, or the sails are aback. To solve this, reset the vessel on course and re-engage pilot.
