Built-in receiver On/Off,
2 channels
2-channel built-in receiver On/Off for permanent installation; for placement in a connection- or wall box. Can be connected to an existing power switch with 230 V AC control. The MCMR-3000 needs both a phase and a neutral connection. The receiver is fully compatible with other System Nexa products.
SAFETY
Read all the instructions carefully first. Call in a professional if necessary. Next cannot be held liable if the product is used for any purpose other than that for which it was designed, or if the associated instructions are not followed. Never connect lights or any equipment that exceeds the maximum stated load of the receiver, as this can result in faults, short circuits,s or fire. Do not attempt to repair the product. The product contains no serviceable parts.
INSTALLATION
Make sure that the wires are free from voltage by disconnecting the current in
the electrical panel.
Connect the phase (Live) to L, the outgoing power line (load) to O1/O2,
neutral to N, and the power switch to S1/S2, see the circuit diagram.
PROGRAMMING
1. Connect voltage to the MCMR-3000
2. Briefly press the programming button for the required channel; the LED
indicator starts to flash.
3. Press the “ON” button for the selected channel on a System Next
transmitter within 12 seconds.
CONFIRMATION OF PROGRAMMING

indicator starts to flash.
2. Press the “OFF” button for the selected channel on a System Next
transmitter within 12 seconds.
CONFIRMATION OF DELETION
The LED indicator on the receiver flashes slowly for 2 seconds.
DELETION OF ALL MEMORY SLOTS
1. Press the programming button and hold it down for 6 seconds. The LED
indicator starts to flash quickly.
2. Release the programming button and then press it briefly once more.
CONFIRMATION OF DELETION OF ALL MEMORY SLOTS
The LED indicator on the receiver flashes slowly for 2 seconds.
MEMORY
The MCMR-3000 has 16 memory slots per channel. When all the memory slots for a
channel are full, the oldest one will be deleted when a new one is programmed.

5. With Nexa Bridge
SAFETY AND INFORMATION
Range indoors: up to 30 m (optimal conditions). The range is heavily
dependent on local conditions – such as if there are any metals nearby. For
example, the heavy metal coating in low-emission energy glass has a negative
impact on the range of the radio signals. There may be limitations on the use
of the unit outside the EU. If appropriate, check that the unit complies with
the local regulations.
Max. load: Never connect lights or equipment that exceeds the maximum
load of the receiver. This can result in faults, short circuits,s or fire.
Life-support equipment: Never use Nexa products for life support
equipment or other devices where faults or disruptions can have life-
threatening consequences.
Disruptions: All wireless units can be affected by disruptions that may
have an impact on performance and range. The minimum distance between two
receivers should therefore be at least 50 cm.
Repairs: Do not attempt to repair the product. It does not contain any
serviceable parts. Waterproofing: The product is not waterproof. Make sure
that it is
always dry. Moisture will corrode the electronic components inside and may
result in short circuits, faults, and the risk of electric shock.
Cleaning: Clean the product with a dry cloth. Do not use chemicals,
solvents, or potent cleaning agents.
Environment: Do not expose the product to extreme heat or cold, as this
may damage the electronic circuits or shorten their service life.
