Installation When mounting a mobile holder, ensure that the phone display is clearly visible for the user. • Your service technician or dealer may be able to provide you with information on alternatives for mounting the equipment suitably in your vehicle without requiring drilled holes. • Do not smoke when working on the car. Ensure that there is no source of fire or flame nearby. • Take care not to cause damage to electrical cables, fuel or brake lines, or safety equipment during installation work. • RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles such as electronic fuel injection systems, electronic antiskid (antilock) braking systems, electronic speed control systems, and airbag systems. Should you notice a fault or change in the operation of such a system, contact your car dealer. • Ensure that cables are placed so that they will not be subject to mechanical wear and tear (for example, not laid under car seats or over sharp edges). ■ Integration with a car radio system The car kit can be connected to a car radio system in three different ways. Select the appropriate option according to the parts supplied in the sales package. For information about the connectors on the hands-free unit HF-22, see "Hands-free unit HF-22," p. 24. You can connect the car kit to a loudspeaker with an impedance of at least 2 ohms. The optimal impedance for the car kit is 4 ohms. If the impedance is over 8 ohms, the output power is significantly lower than normal. 18
