How to Calibrate the Compass in Your Suunto Vector

By Techwalla Contributor

The Suunto Vector wristop is the most legendary of all the Suunto outdoor devices. Equipped with an altimeter, barometer and electronic compass, the Suunto Vector keeps track of your activities and provides you with information to make decisions in situations where knowledge about your surroundings is essential for your safety.

Things You'll Need

  • Suunto Vector wristop

Step 1

Go to the Vector's Compass screen. Press the "Mode" button until the small arrow is beneath the word "Comp." Press the "Select" button twice when in the main compass mode. Field 1 will display "CMP" and Field 3 will display "CAL."

Step 2

Press and hold the "Select" button for two seconds. The text "PUSH" will begin to flash in Field 2.

Step 3

Press the "-" button to start calibration. "360°" will appear in Field 2. When this occurs, hold the Suunto Vector level and start to slowly turn the device in a full circle, keeping it in a level position. The direction of turning does not matter. The lit segments on the wristop will be turned off as the turning proceeds. When the first full circle is completed, the Suunto Vector will inform you within one minute whether the calibration was successful by displaying "dOnE" in Field 2, or if the process needs to be repeated by displaying "PUSH" and "-" in Field 2.

Step 4

Press the "Mode" button to accept the calibration once it is successful and exit the calibration mode.

Tips & Warnings

  • It is best to calibrate the compass outside.
  • A compass calibration should be done when the Suunto Vector has been subjected to close proximity of magnetic sources, extreme cold weather and every time the battery is replaced. It is also recommended to calibrate the compass before using the compass the first time and every time leaving for a hike where the compass will be used.
  • You may need rotate the compass more than twice around in order for the calibration to be completed.
  • It is important to hold the Suunto Vector level during the calibration process to ensure accuracy.
