1. For best reception the location of the receiver should be visible to
the operator at all times.
2. The location selected should not be exposed to high levels of
electric noise. Mounting the receiver next to an unshielded variable-
frequency drive may cause radio interference. Always locate the
receiver as far away from variable frequency drive and electric
motor as possible.
3. Ensure the selected location has adequate space to accommodate
the receiver. If an external antenna is used, to avoid the possibility
of antenna damage always locate the receiver where the antenna
is free from any obstacles.
4. When installing an external antenna make sure the MCX jack
located on the decoder board inside the receiver is connected and
jumper set to “EXT” position.
5. For better reception, make sure the receiver is in an upright position.
6. Drill four holes for mounting bracket type 1 and two holes for mounting bracket type 2 on
the control panel, wall or location where the receiver is to be installed.
7. Make sure the screws, bolts or shock absorbers are tightened after installation (not
provided with the system).
8. Install suppressor on all contactors being driven by Flex relays. This is due to the
possibility of voltage spike on the contractors.
9. Slide down the receiver along the guided track to secure the receiver to the mounting
bracket.
10. Remove the receiver by pressing down the bracket release and pulling the receiver
upward until it clears the guided track.
