Antenna coupler (9)
You can install a separate antenna coupler (not included in the sales
package) to connect an external antenna. A range of antenna couplers
may be available for mobile phones and phone holders. An antenna
coupler may improve in-vehicle reception of the mobile phone.
Please check the compatibility of couplers with the manufacturer.
GSM antenna (12)
A compatible GSM antenna (not included in the sales package) enables
optimized wireless connections. To use an external antenna, you need
an antenna coupler and/or compatible phone holder (sold separately).
Note: If you have installed an external antenna, remember
that in order to comply with RF exposure requirements for
mobile transmitting devices, a minimum distance of 20 cm (8
inches) must be maintained between the antenna and all
persons.
