Each keypad can be connected directly to the MC-86 (option “A”) or can be “daisy-chained” to another keypad that is connected
to the MC-86 (option “B”). The Zone Dial on each keypad determines the zone number that it controls; select 1, 2, 3, 4, 5, or 6.
Note that additional settings, including 0 and 7 thru F are available for combining up to three MC-86s (for paging). Please con-
tact us for more details since this option requires modification to the second and third MC-86.
It is not necessary for a Keypad
with a Zone Dial setting of “X” to be connected to the Network RJ-45 input for Zone “X” (see option “B”).
When more than one keypad is set to the same zone number, adjusting the setting of one keypad (either by pressing buttons
on that keypad or using a remote control for that keypad) will adjust other keypad(s) set to the same zone number.
Although combinations of Option “A” and “B” are acceptable and very often necessary, we highly recommend connecting at
least one keypad from each zone directly to the MC-86 as shown in option “A” in order to make use of an audio component
located within that zone. Each Cat5 cable that connects directly from a keypad to the MC-86 can carry the audio signal of only
ONE audio component (see “NOT OK” above).

Zone Dial
Setting the Zone Dial
It is best to set the Zone Dial on each
Keypad BEFORE ever connecting the
Keypad to the MC-86. NEVER ADJUST
THE ZONE DIAL WHILE THE KEYPAD
IS POWERED ON. Doing so can result
in “stored memory” that can cause the
Keypad, and potentially other Keypads in
the system, to malfunction. Should this
occur you will need to clear the memory
for EVERY Keypad in the system by per-
forming the following to each keypad:
1) Turn the Keypad off, wait at least one
second, and turn the Keypad back on.
2) Take the volume level down to “00” and
then back up to “99”.
3) Turn the Keypad off, wait at least one
second, and turn the Keypad back on.
4) Set the volume level to your preferred
listening level (“92” or lower).
