Declination Angle - Oregon Scientific RA123 Bedienungsanleitung

NOTE The compass should be calibrated:
• Before you use it for the first time.
• When the battery is replaced.
• Before you leave for an extended outdoor activity.
• Whenever it is exposed to strong magnetic sources,
extreme cold, or you suspect that other environmental
conditions have affected the compass readings.
• If you notice that the compass is not showing the
direction correctly.

DECLINATION ANGLE

Declination is the angle between where a compass
needle points (magnetic North Pole) and the true North
Pole. The declination angle can vary from 0-30 degrees
East (E) or West (W) and can be found on most maps
or on the Internet.

When you set the declination angle on the compass you
compensate for the difference between true and magnetic
north. This makes the compass reading more accurate.
To set the declination angle:
1. Press COMPASS to navigate to Compass mode.
2. Press and hold COMPASS to enter settings mode.
3. Press ALT / + or BARO / - to navigate to Declination
mode.
4. Press TIME to confirm and move to the next setting.
5. Press ALT / + or BARO / - to change setting. The setting
options are as follows: ON / OFF; WEST/EAST (only if
ON is selected); degree of declination angle.
6. Press TIME to confirm.
