Why does my NorthStar 957 2201 lose satellite signals?
If satellite signals are frequently lost or the NorthStar 2201 GPS works in one direction but not the opposite, it might be partially shaded by metallic objects. Try re-positioning or raising the 2201 GPS to ensure a better view of the sky.
How to obtain WAAS satellites on NorthStar GPS 957?
If you're having trouble acquiring WAAS satellites on your NorthStar GPS 957, first verify that WAAS is available in your current location. Then, reset the satellite elevation setting to its default of 10 degrees. Lastly, confirm that the DIFFERENTIAL OPERATIONS option is set to either WAAS or AUTO.
What to do if NorthStar GPS locks up with chart card?
If your NorthStar GPS 957 system freezes when using a chart card, the card might be faulty. Remove the card and inspect both the card's pin area and the 957's pins for any damage. If the 957's pins are bent, do not insert another card to prevent further damage. If the pins are intact, try inserting a new card after turning the power off.
How to fix 'COMM FAIL TOO FEW SATS' on NorthStar GPS 957?
If the error message 'COMM FAIL TOO FEW SATS' appears on your NorthStar GPS 957 display, take the following steps: * Check the antenna and wiring connections while the power is on. * Disconnect the 2201 from the 957, then measure the 7-pin 2201 connector for 10 - 36 volts at pin 7, ground at pin 6. * Check the 2201’s remote-on: Pin 5 should measure less than 5 ohms to ground. * After testing above, re-connect the cable and press the PWR key to turn the 957 off, then turn it back on again. * Ensure that nothing is obstructing the 2201’s view of the sky. * Allow up to 30 minutes for full initial acquisition, as the almanac may not be complete.
Why won't my NorthStar GPS 957 turn on?
If pressing the PWR key doesn't start your NorthStar GPS 957, check the fuse and the power supply to the unit. If this doesn't resolve the issue, the display may have failed.
How to improve SNR readings on NorthStar GPS 957?
If you're getting poor SNR readings on your NorthStar GPS 957 even after running it for a while, check the antenna location. It should have a clear view of the sky. Also, make sure the antenna is clean and free from ice, snow, or exhaust soot.
Why does my NorthStar 957 GPS show color bars instead of video?
If color bars are showing instead of the video overlay image on your NorthStar GPS, ensure the video image is turned on by pressing STAR to display the VIDEO SETUP screen. Also, check the cables and connectors for any issues, and verify that the video equipment is functioning correctly.
Why does NorthStar GPS 957 screen dim automatically?
If the display screen on your NorthStar GPS 957 dims after being on for a while, it's likely activating its auto-dimming mode. This feature helps protect the display and reduce power use when the GPS is running too hot for its environment.
