1. Antenna Condition
Please refer to the internal photo for the antenna
condition.
- The antenna is located at the bottom to avoid the influence of
hand holding. - The middle part is a battery, and the hand holding part has no
antenna space. - There are LED lights, buttons, motors, and sensors on the top
of the PCB, without antenna space.
