In some countries the use of telecommunication terminals is subject to a license.
Please check with local authorities in the country where the system is in use to verify whether the
license in question is mandatory.

SUGGESTIONS AND RECOMMENDATIONS
Check that receiver and transmitter have the same operating frequency.
Any transmitter can only work if it is used with the receiver operating in the same band
and frequency.
ATTENTION
Before powering the transmitter make sure that the mains voltage matches the input voltage
specified on the power supply.
The transmitter must only be powered using the supplied power supply.
Power the transmitter by connecting the power supply to the “DC MAIN INPUT” connector located
on the rear of the receiver.
Interference problems
To avoid interference problems:
- keep the transmitters at least 1/1.5 metres away from ANY receiver
- should the transmitter and the receiver have to operate at less than 1m from each other,
fully lower the transmitter antenna.
- the effective range depends on the presence of any noise on the selected channel, of
obstacles between transmitter and receiver or of signal reflections linked to the usage
environment.
Simultaneous use of multiple systems
EME-ONE is suitable for the simultaneous use of multiple systems (4 for each band).
We recommend that you leave at least a 1-channel gap (0,2,4,6) or (1,3,5,7).
In case of trouble while simultaneously using different systems, check the frequencies in use; in
particular, avoid frequency conflicts (check the transmission channels)
