Receiver Installation
The Flex Duo factory setting uses an internal antenna. If an external antenna kit is required, ensure
the MCX antenna cable located on the RF/decoder board inside the receiver is connected and the
jumper is moved from the INT to the EXT position.
Standard Optional Mounting Bracket
For best reception, the receiver and/or external antenna should always be mounted in a location with a clear line
of sight to the transmitter. Ensure the mounting location of the receiver is not exposed to high levels of electric
noise. Mounting the receiver next to a variable frequency drive or an EMI / RFI generator may cause radio
interference.
Once the proper mounting location is identified, drill four holes (standard) or two holes (optional mounting bracket)
on the control panel, wall, or location where the receiver is to be installed.
If a mounting bracket is used, leave enough slack in the harness to accommodate sliding the receiver on and off
the bracket.

General Operating Procedures
The Flex Duo system consists of the transmitter(s) and receiver containing all of the required settings to work
upon quick installation.
The default operation of the Flex Duo system has the two pushbuttons configured as an interlocked pair to perform
as motion control with the corresponding output relays setup for momentary contact closure. Pressing both buttons
at the same time after start-up will result in no output because the buttons are configured as interlocked.
Turn System On
1. Install the provided batteries in the transmitter and power on the receiver.
2. Elevate the STOP button to power on the transmitter.
3. Perform the START command by pressing and holding both PB1 and PB2 at the same time for 1 second to
activate the receiver MAIN relays and to establish a communication link with the receiver.
When the receiver MAIN relays are activated, the Status LED will change from constant green to constant orange
(system on). Press any pushbutton on the transmitter to begin operation. Pressing any pushbutton prior to
executing the START command at startup will result in no signals transmitted (Status LED blinks orange).
Turn System Off
Press the STOP button down to power off the transmitter, disconnect the receiver MAIN relays, and to disconnect
the communication link with the receiver.
After 5 minutes of inactivity (pushbutton not pressed), the receiver MAIN relays are temporarily disconnected. The
Status LED blinks 3 reds and then shuts off. Press any pushbutton to resume operation.
