Antenna coupler and external antenna
An antenna coupler can be used to connect an external antenna to the
car kit. The external antenna improves the reception of the mobile
phone in a car. For availability, contact your dealer.
Note: In order to comply with RF exposure guidelines, install the
external antenna so that a minimum distance of 20 cm can be
maintained between the external antenna and all persons, with
external antenna gain not exceeding 3 dBi.
