5 Antenna Information

5.1 Antenna Type

BT3L uses an onboard PCB antenna.

5.2 Antenna Interference Reduction

To ensure optimal RF performance, it is recommended that the antenna be at least 15 mm

away from other metal parts. If metal materials are wrapped around the antenna, the

wireless signals will be reduced greatly, deteriorating the RF performance. Because BT3L

is inserted to the PCB, sufficient space needs to be reserved for the antenna.
