NOTE : BASE UNIT/KEYBOARD
CONNECTION/PROGRAMMING.
1 — THE BASE UNIT/KEYBOARD PROGRAMMING/CONFIGURATION CANNOT BE CAR-
RIED OUT IF THE DEVICES ARE CONNECTED TO THE LINK NETWORK. THEREFORE, IT
IS FIRST NECESSARY TO CONFIGURE THE MASTER AND SLAVE DEVICES (WITH
RELATED KEYBOARDS) AND THEN CONNECT THEM TO THE LINK NETWORK.
2 — “FLICKERING” OF THE DISPLAYS ON THE KEYBOARD INDICATES THAT THE CON-
NECTED UNITS ALL HAVE THE SAME ADDRESS: DISCONNECT THE LINK NETWORK
AND PROGRAM EACH UNIT AS DESCRIBED ABOVE.
