1. For best reception the location of the receiver should be visible
to the operator at all time.
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 obstructions.
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 (not provided with the system) are
tightened after installation.
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.
