Antenna coupler and external antenna
An antenna coupler is required to connect an external antenna. The
external coupler improves the cellular signal reception of the mobile
device in a car. For compatible antenna couplers and external antennas,
contact your dealer.
Note: In order to comply with RF exposure guidelines, install the
external antenna so that a minimum distance of 20 cm (8 inches) can
be maintained between the external antenna and all persons, with
external antenna gain not exceeding 3 dBi.
