How can i speed the gps signal reception up?

Satellite signal reception quality is considerably impacted by the environment and your movement. To facilitate reception, we recommend the following during signal detection: 1. Positioning yourself in a clearing away from buildings and trees. 2. Placing the watch on the ground.

What is fastfix & how do i know if it is up to date?

FastFix technology helps your watch pick up the satellite signal more quickly. You can start exercising straight away.

In concrete terms, FastFix picks up satellite ephemerides. These ephemerides are valid for 7 days. So, to enjoy FastFix technology all the time, you must update the FastFix on your product once a week by synchronising your ONmove 200 with ONconnect. Otherwise, it will take longer to pick up the satellite signal.

To find out whether FastFix is up to date on your watch, go to the Settings > About > FastFix menu. This shows whether FastFix is up to date or not.

If you do not want to be limited by this 7-day period, you can also update the FastFix manually as follows:1. Connect your ONmove 200 to your computer. Access My Computer3. Delete the ONCONNECT.JSON file4. Start ONconnect to view the FastFix update information 5. Unplug your device so that the FastFix update can be completed.
