Special Requirements
Wireless Performance. The wireless RF system is designed to operate reliably in
a typical enclosed AV venue environment at up to 75M. This can be reduced due
to high levels of ambient RF interference so to ensure optimum performance
please observe the following guidelines:
Ensure the MicroCue 2 aerial is vertically orientated.
Position the MicroCue 2 aerial within line-of-sight of the handsets, without
large metallic objects in between as much as possible. The aerial can also
be placed remote from the main unit using a 50 ohm BNC-BNC coaxial
extension cable if required (max cable length: 4m).
Avoid electrical/electronic interference by positioning the MicroCue
2 main
unit away from equipment as much as possible.
PC Computer USB Interface. Suitable only for PC systems running a WINDOWS
XP or later operating system. To ensure optimum performance, we can only
recommend using the USB A-B type cable supplied.
Mac Computer USB Interface. When connecting to a Mac computer USB input,
when the Mac keyboard assistant requests keyboard confirmation, simply ‘cancel’
this request and MicroCue will operate normally.
Radio Frequency System
MicroCue uses a proven RF system for all wireless applications.
Operating frequency: 434.075MHz (UK, Europe & USA)
Transmission method: FM (Pure FSK)
Maximum transmit power: 10mW (EU) 11mV/m @3m (USA)
This frequency is open and licence exempt for UK, Europe and USA. Other
countries should consult their respective authorities.
The system used is a coded transmission where the receivers are programmed to
the transmitters which each have individual and unique codes. Nominal range of
the transmitters is 300M open field or typically 75M in an enclosed venue.
