Installation Guide

● If the quality of the GSM signal is good: keep the original antenna installed on the Box.
● If the signal quality is insufficient: move the original antenna out of the cabinet; use an RF
extension cord with SMA connector, up to 2 meters, + 1 adhesive support to hold the
antenna.
● If the signal quality is still insufficient: use a high-gain antenna with a maximum of 10
meters of cable; this antenna can, for example, be moved to the outside or to the other
floors to obtain a better signal quality. Please note that, beyond 15 meters of cable, the
GSM signal is significantly weakened.
