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 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).
