This hands-free kit can be used by children aged 8 and older and by persons with reduced physical, sensory or
mental abilities or lack of experience and knowledge if they are supervised or have been instructed on the safe
use of the hands-free kit and understand the resulting risks. Children must not play with the hands-free kit.
Cleaning and user maintenance must not be carried out by children without supervision. Always keep plastic
packaging away from children as it poses a suffocation risk.
If smoke is produced, or there are any unusual sounds or smells, disconnect the hands-free kit from the power
supply immediately. In such cases, the hands-free kit should not be used until it has been inspected by authorised
service personnel. Never inhale smoke from a potential device fire. If you have inhaled smoke, however, consult
a doctor. The inhalation of smoke can be harmful.
The hands-free kit and its accessories must not become damaged in order to prevent hazards.
Ensure that no fire sources (e.g. burning candles) are placed on or near the hands-free kit. It poses a fire hazard!
The hands-free kit must not be thrown into a fire because the integrated battery may explode.
The hands-free kit must never be exposed to any direct heat sources (for example, heaters) or direct sunlight or
artificial light. Also avoid contact with dripping water and splashes and corrosive liquids. Do not use the hands-
free kit near water. In particular, the hands-free kit should never be submerged in liquid (do not place any items
filled with liquid, e.g. vases or drinks near the hands-free kit). Also ensure that the hands-free kit is never subjected

hands-free kit could be damaged.
In the event of improper use of the battery, there is a risk of explosion and leakage. Only replace the battery with
an identical model or one recommended by the manufacturer. Never replace the battery in an environment
where there is a risk of explosion. During the insertion or removal of the battery, there might be a spark that could
cause an explosion. Areas where there is an explosion risk are usually labelled as such, although not always
clearly. This includes tank areas such as e.g. below deck on boats, refuelling or fuel storage areas, areas in
which the air contains chemicals or particles such as e.g. cereals, dust or metallic powder as well as in all areas
in which you are normally instructed to switch off your engine.
The battery must not be thrown into fire. Risk of explosion!
The terminals of the battery must not be short-circuited. The battery must not be opened, damaged or deformed.
Risk of explosion!
There is a risk of suffocation if you swallow the battery.

Car charger adapter
Always handle the car charger adapter by the connector and do not pull on the connection cable itself.
Do not place furniture or other heavy objects on the connection cable and ensure that it is not kinked.
Never tie a knot in the connection cable and do not tie cables together. Ensure that the connection cable is
placed so that no one can trip over it and it does not cause an obstruction.
Do not use adapter plugs or extension cables and do not make any alterations to the connection cable. If the
connection cable is damaged, it must be replaced by the manufacturer or its customer service representative or a
similarly qualified person to prevent any safety hazards.

Charging the lithium-ion battery
Charge the lithium-ion battery fully before its first use. To do so, connect the USB connector of the enclosed car
charger adapter to the USB charging socket (7) of the hands-free kit. Then insert the car charger adapter into an
appropriate power outlet of your vehicle. The LED indicator (2) lights up red while charging. A full charge cycle takes

adapter from the power outlet and the hands-free kit.
Charge the battery only when the engine is running to save the battery of your vehicle.
Switching on/off the hands-free kit
Press the multifunction button (5) for approx. 5 seconds until a beep sounds and the LED indicator (2) flashes blue. The
hands-free kit is now ready to use.

Dial-up with compatible mobile phones

SilverCrest SFA 30 A1

details, please read the instructions of your mobile phone. Select the device "SFA 30 A1" from the list of devices which
are found.
The name of the hands-free kit "SFA 30 A1" now appears in the list of devices connected to your mobile phone. The
hands-free kit is now in standby mode and the LED indicator (2) flashes blue once at regular intervals. Once the
mobile phone is switched off, it flashes blue twice.
You can connect or pair additional devices to the hands-free kit in the same manner. The pairing begins for each
device with the hands-free kit switched off as described above.
The hands-free kit then has several "known" devices. This status is a prerequisite for an active connection between the
hands-free kit and other devices.
The number of devices that can be actively connected to the hands-free kit is limited to two. As soon as one or two of
the known devices are in the vicinity of the hands-free kit, the connection to these devices is established automatically.
You may need to confirm the connection on your mobile phone. If a third known device is now in the vicinity of the
hands-free kit, the connection is blocked as long as 2 active connections exist. If one of the two active connected
devices is no longer paired, pairing is possible for the third (waiting) device. Once the hands-free kit has established a
telephone connection with one of the mobile phones which is paired at the same time, no telephone connection can
be established with the second device via the hands-free kit. This blocking is cancelled once the first telephone
connection has ended.
The pairing process can take up to 30 seconds depending on the mobile phone which is used.
