How to Position the Receiver Unit
For optimal performance, the Receiver unit should be placed
in a location where there is little or no RF interference.
In most cases, however, you will notice no RF interference.
There may be RF interference when other appliances
(such as WiFi base stations, audio/video devices, microwave
ovens, or wireless telephones) are operated nearby.
The LED on the Receiver unit indicates the
amount of RF interference.
The amount of RF interference present is indicated by the
rate at which the LED blinks and the brightness of the LED
when blinking (a higher rate of blinking and a brighter
light means more RF interference).
To avoid interference, place the Receiver unit in a
position in which the Receiver unit LED blinks and burns
as little as possible.
Remark Do not operate the Marantz touch screen remote control while positioning the
To find the position with the least amount of RF interference, try out the
following steps:
1 Try to create the worst-case scenario, by turning on all devices that
may cause RF interference. If the RF Extender and the Marantz touch
screen remote control works properly in this scenario, they will
certainly work in other situations.
2 Extend the antenna of the Receiver unit, and direct it upwards.
