Precautions and Tips for Using Compass

1. Keep the watch away from any magnets or appliances that contain magnets
or generate magnetic fields such as mobile phones, speakers, motors, etc.
2. This watch points to the magnetic north, which is slightly different from
true north. Check the "What is Magnetic Declination" section on p.30
for more details.
3. Perform compass calibration (see p.39) frequently, or under the following
conditions:
• First time using the compass
• When the measuring result is suspected to be incorrect
• When the battery has been replaced
• When the watch is in a different location from where it was
previously calibrated
4. Avoid measuring direction in the following conditions:
• Watch is placed close to magnetic objects, metal objects
or electrical appliances
• Watch is placed inside a moving object or a ferroconcrete building
