5.6. 

LEVELLING OF THE REPEATER 

 
After software-login, the repeater must be levelled so that the highest output power is 
achieved without reaching the ALC (Automatic Level Control). 
 

∗

 Note: 

When the local software configuration is finished, don´t forget to 
switch back DIP-switch 2 of the mode-switch to position ON, 
otherwise the remote mode via modem will not work!
