    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

    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
