Example: 
 
A gain of 74 dB is required in the UL- and DL-path, module 1 is set to channel 96 and 
module 2 to channel 113. The repeater has a gain of max. 82 dB. 
 
1. Calculate the difference between the max. repeater gain and the required gain. 
 
Max. repeater gain:   
 
 
     82  dB 
Required gain for UL and DL: 
 
     74  dB 
 
 
 
------------- 
Required attenuation for UL and DL: 
       8  dB 
 
2. Turn switch S7 as well as S8 to position 4 to set an attenuation of 8 dB for UL- and 
DL-path. 
 
3. Set channel 96 for module 1: 
 
Turn switch S1 to position 0: 
 
       0 
Turn switch S2 to position 9: 
 
     90 
Turn switch S3 to position 6: 
 
       6

Channel: 
 
 
 
 
     96 
 
4. Set channel 113 for module 2: 
 
Turn switch S4 to position 1: 
 
   100 
Turn switch S5 to position 1: 
 
     10 
Turn switch S6 to position 3: 
 
       3
