Initializing the GPS receiver
In the upper right-hand corner of the display, the GPS symbol appears. As soon as
data from at least 3 satellites is received, the symbol changes to (
GPS Ready).
Setting the volume
The volume of the spoken driving instructions can be adjusted during navigation.
On the NAVIGON 8100T, there are two ways to adjust the volume.
Using Hardware Keys
Hardware keys on the sides of the device can be used to control volume.
On the left side of the device:
Tap (Mute) to mute the volume. Tap again to restore volume.
Tap (Louder) to increase the volume.
Tap (Softer) to lower the volume.
Note: If possible, position the device with a clear line of sight to the sky to successfully
receive messages from the GPS satellites.
Note: GPS initialization requires data from at least three satellites. If GPS data is not
available, the receiver will not initialize.
Note: It can take up to 20 minutes to initialize the integrated GPS receiver for the first
time.
Note: Each time you turn on the device, GPS receiver initialization begins. When GPS
data is available, reception starts within one minute.
If the navigation device has been switched to standby for more than a week, the next ini-
tialization can take up to 10 minutes.
Note: If the GPS symbol displays GPS Ready after considerably less than 20 min-
utes, it is advisable to leave the receiver switched on for at least an additional 15 min-
utes to ensure reliable operation.
Caution! The GPS receiver requires a constant supply of power. Leaving the device
plugged into your cigarette lighter for a longer period with the vehicle turned off could
drain the vehicle battery.
