Recommended Operating Conditions

Wireless Specifications

Antenna

Avoid handling the module by its antenna. For best results, place all devices so that the 
antenna points to the ceiling. Devices placed close to the ground may have a 
significantly reduced range. In the event of communications difficulties, try changing 
the orientation of the module.
