[. . . ] · While in base operating mode, the repeater · Set the repeater to simplex, when other another station. is set to duplex. 13 MAINTENANCE 5 I Fuse replacement If a fuse blows or the repeater stops functioning, try to find the source of the problem, and replace the damaged fuse with a new, rated fuse. RWARNING: DISCONNECT the AC power cable and/or DC power cable from the repeater. Otherwise, there is danger of electric shock and/or equipment damage. D REG unit q Remove the top cover as shown on p.
