To attach the Active Dock, press the suction cup firmly against the windscreen
on an area where the glass is flat. Then twist the rubber grip near the base of
the Active Dock in a clockwise direction until you hear a click.
Home dock
The Home dock is used for charging your TomTom GO when it is not in the
car and for connecting your GO to your computer.
When connected to your computer, you can use TomTom HOME to manage
your GO.
GPS reception
When you first start your TomTom GO navigation device, the device may
need a few minutes to determine your GPS position and show your current
position on the map. In future, your position will be found much faster, usually
within a few seconds.
To ensure reception of a strong GPS signal, you should use your device
outdoors. Large objects such as tall buildings can sometimes interfere with
reception.
The TomTom GO 940 includes Enhanced Positioning Technology or EPT. EPT
is automatically used to estimate your location when the GPS signal is lost
while you are driving, such as when you are driving through a tunnel. When
EPT is being used, an icon is shown on the Status bar.
Safety Notice
Your TomTom GO contains a GSM/GPRS module which can interfere with
electrical devices such as cardiac pacemakers, hearing aids and aviation
equipment.
Interference with these devices may endanger the health or life of others.
Do not use near unprotected electrical units nor in areas where the use of
mobile telephones is prohibited, such as hospitals and airplanes.
Take care of your device
Never leave your TomTom GO navigation device or accessories on view when
you leave the car or they may become an easy target for thieves.
You can set a password for your device which must be entered every time you
start it.
It is important to take care of your device.
• Your device is not designed for use in extreme temperatures and any such
exposure may cause permanent damage.
• Do not open the casing of your device under any circumstances. Doing so
may be dangerous and will invalidate the warranty.
• Wipe or dry the screen of your device using a soft cloth. Do not use any
liquid cleaners.
