Introduction:
Signal enhancer/Signal Amplifier can add the transmitting distance between the button and the host. It receives the signal from the button wirelessly and then enhance the signal to transmit to the host. It is applicable for HY-2677C, HY-2677E, HY-2677F, HY-2677G, HY-2677K,HY-2613A systemS,  The installation of the ignal enhancer is very simple and no signal line is needed
2) When the site is very large (more than 2,000 square meters usually) or the signal is severely shielded in the building, several signal enhancers can be adopted to realize the no-blind coverage. Furthermore, the signal relaying function of the signal enhancer can ensure the clients with large sites to use the MMCall products swimmingly 2) When the site is very large (more than 2,000 square meters usually) or the signal is severely shielded in thebuilding, several signal enhancers can be adopted to realize the no-blind coverage.
