OPERATION NOTES

Continued from previous page
» EU Models: Up to 2 pairs of Sender and Receiver units can be
operated in the same environment. Local RF interference can limit
the number of units that can be used. Each Sender unit needs to be
placed at least 1 meter apart for optimum performance. If additional
Sender / Receiver pairs are to be used, each set of units must be
placed beyond the reception range (100 feet / 30 meters) of each
other in order to prevent interference.
• IR back-channel compatibility:
» Due to complexity in some manufacturers’ IR codes, not all 38kHz IR
devices may be compatible with the IR Back Channel of the
Wireless for HDMI. For a list of compatible brands, see
www.gefentv.com
• Operational Limitations:
» Regarding US and EU models, note that all RF devices are designed
by compliance regulation to accept interference from all other
devices. Operation of wireless products is therefore dependent on the
environment they are in. Other RF products, even ones that seemingly
might not be in the frequency range, do create harmonics and other
artifacts that could interfere with the operation of the Wireless for HDMI.
IMPORTANT: Only products with 38 kHz IR carrier frequency
are compatible. If in doubt, please check with the equipment
manufacturer.
