(not through the center hole in the C-bracket).
Connection Cables
Connection cables (sold separately) are
available in 6 ft. (MMC-6) and 25 ft. (MMC-25)
lengths to suit different mounting locations.
A Y-splitter (MMC-2Y) (sold separately) may be
used to connect an additional remote to a
single source unit.
Each remote controller may be connected
a maximum 75 ft. (22.8 m) of cable length
away from its source unit. Remote controllers
and cables utilize a 5-pin connector with a
watertight threaded collar to securely mate
their ends together. Connectors are keyed
and must be aligned to fit properly. Once
connected, make sure that cables are securely
routed using cable ties or wire clamps, keeping
connections away from areas where they could
be submerged in water.
LED Source Indicators
Blue LED indicators on the front of the remote
controller are used to report the currently
selected source. Pressing the
button
will cycle through each source option (RADIO/
USB/Bluetooth®/AUX).
Since the MMR-20 does not incorporate a
display screen, all available tuner options (AM/
FM/WB SiriusXM®) are combined as “RADIO”.
When RADIO is chosen, the last tuner used
will be selected. To change tuners, use the
MediaMaster® source unit.
