NOTE: When you activate GPS for the first time, or have not
used it for a long time, it might take longer than usual to get a GPS
fix. Subsequent GPS starts will take less time.
TIP: To minimize GPS initiation time, hold the watch steady with
GPS facing up and make sure you are in an open area so that the
watch has a clear view of the sky.
Troubleshooting: No GPS signal
• For an optimal signal, point the GPS part of the watch upwards.
The best signal can be received in an open area with a clear view
of the sky.
• The GPS receiver usually works well inside tents and other thin
covers. However, objects, buildings, dense vegetation or cloudy
weather can reduce the GPS signal reception quality.
• GPS signal does not penetrate any solid constructions or water.
Therefore do not try to activate GPS for example inside
buildings, caves, or under water.
3.20.2 GPS grids and position formats
Grids are lines on a map that define the coordinate system used on
the map.
Position format is the way the GPS receiver's position is displayed on
the watch. All the formats relate to the same location, they only
express it in a different way. You can change the position format in
the watch settings under GENERAL » Format » Position format.
