3. Use the GPS module

■ Power key functions

The GPS module has one function key—the power key. However, the key
has three different functions:
One-second key press—switches power on and off
Ten-second key press—resets the GPS module
Short key press—shows the GPS module status in night mode.
In some applications, the GPS module can be set to night mode from the
mobile phone. In night mode, the indicator lights are always off when the
power is on, the Bluetooth connection is active, and the GPS module can
determine its position. In night mode, the status of the GPS module can be
checked by a short press of the power key (the indicator lights appear briefly).
When the GPS module is switched on, it takes some time for the device to
position itself. This time varies depending on how long the GPS module has
been turned off and how well it can receive the satellite signals. This time is
longer if the battery has been removed. In optimal conditions, start-up
positioning takes about one minute.
The GPS module should only be used outdoors to allow reception of GPS signals.
The GPS should not be used for precise location measurement, and you
should never rely solely on location data form the GPS module. Virtually all
digital cartography is always inaccurate and incomplete to some extent.
Never rely solely on the cartography provided for use in this device.
