Troubleshooting V800 GPS
Make sure GPS recording is set on. Go to Settings > Sport Profiles, and choose your sport and set GPS recording to High accuracy, Medium accuracy or Power save, long session. Or press and hold LIGHT in pre-training mode to access the sport profile settings, and adjust GPS settings.
To catch GPS satellite signals, go outdoors and away from tall buildings and trees. Wear V800 with the face upwards on your wrist. Keep it in a horizontal position in front of you and away from your chest. Keep your arm stationary and raised above the level of your chest during the search: Stand still and hold the position until V800 has found the satellite signals. The percentage value shown next to the GPS icon indicates when the GPS is ready. When it reaches 100 %, OK is displayed, and you can start your session.
V800 uses SiRFInstantFix™ satellite prediction technology to acquire a fast satellite fix. It accurately predicts satellite positions for up to three days allowing you to find satellite signals in 5 -10 seconds.
For best GPS performance, wear V800 on your wrist with the display facing outwards. Due to the location of the GPS antenna on the V800, it is not recommended to wear it with the display on the underside of your wrist. When wearing it on the handlebars of a bike, make sure the display is facing up.
The best GPS signal reception can be reached when training in an open area where there are no obstructions for the satellite signals. Due to the nature of the GPS signal, for example hills, tall buildings, and trees may block the satellite signal. Rain, fog, and snow may also affect the signal quality. These conditions may result in uneven speed readings during the exercise and cause an uneven speed curve in Polar software even when you have exercised at a steady pace.
Note that your current speed is shown during training only when High accuracy GPS is used. When using Medium accuracy or Power Save modes your average speed is shown.
