Introduction:
1) Signal enhancer can add the transmitting distance between the button
and the host. It receives the signal from the button wirelessly and than
enhance the signal to transmit to the host. It is applicable for the HY-2677A
system, HY-2677B system, HY-2677C system, HY-2677E system and
HY-2677G system. The installation of the signal 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
