control systems or air bag systems. For installation
or service of this device, please consult with the
manufacturer or its representative of your car. Faulty
installation or service may be dangerous and may
invalidate any warranty that may apply to this
device.
Consult with the manufacturer of your car to ensure
that the use of your cellular phone in the car will not
affect its electronic system.
Check regularly that all wireless device equipment
in your car is mounted and operating properly.

Emergency calls

This Bluetooth car handsfree and the electronic
device connected to the handsfree operate using
radio signals, cellular, and landline networks as well
as user-programmed function, which cannot
guarantee connection under all conditions.
Therefore do not rely solely upon any electronic
device for essential communications (such as
medical emergencies).
Remember, in order to make or receive calls, the
handsfree and the electronic device connected to the
handsfree must be switched on in a service area with
adequate cellular signal strength.
Emergency calls may not be possible on all cellular
phone networks or when certain network services
and/or phone features are in use.
Check with your local service provider.
