Descriptions on the Setting: 

a.  The  ICS  micropower  unit  is  placed  indoors,  facing  any  zone  to  be  covered;  receiving  and 

transmitting antenna inside. 

b. the uplink isolation between the receiving and transmitting antenna is 42dB and the downlink 

isolation is 58dB, so the module’s gain can be generally set to be approx. 68dB.

LCD Indication  Description   

Remarks 

 

The  Progress  Bar  in  the  left  has  6 

bars in total:   

1.

  Once  the  module  is  powered  on, 

the 

Progress 

Bar 

will 

roll 

circularly,  indicating  that  the 

module is starting; 

2.

  Once  the  module  is  normally 

started,  the  Progress  Bar  will 

show the downlink received signal 

level strength; 

3.

  In  case  of  failure  in  startup,  all  6 

progress  bars  would  be  lit, 

flashing for alarm.   

The  indication  range  of  downlink 

signal strength:   

0:  no  signal  input  or  no  signal 

detected; 

1 bar: -110~-101dBm ; 

2 bars: -100~-91dBm; 

3 bars: -90~-81dBm; 

4 bars: -80~-66dBm; 

5 bars: -65~-51dBm m; 

6 bars: 

≥-50dBm;
