RF signals may affect improperly installed or 
inadequately shielded electronic systems in cars, 
such as electronic fuel injection systems, electronic 
antiskid (antilock) braking systems, electronic speed 
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.
