Temporary degradation which requires operator intervention is possible. Degradation of performance
could result in interruption or stuttering audio performance or a change in power led indication.
RF wireless communication systems (*) can continue degrade the performance.

Manufacturer’s declaration - electromagnetic immunity (EMI)
The i-Speak complies to harmonised standards according to devices regulations
to maintain basic safety during the expected service life and provides reasonable
protection against harmful interference in a residential installation.
However, degradation of performance can occur by ESD, EFT or by RF communication
equipment, including antennas.
This product is tested to EN/IEC 60601-1-2 Ed.4 and the normatively referenced
standards as specified:

When the i-Speak is degraded in performance or cause harmful interference to radio
or television reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the i-Speak and transmitter or receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• The floors should be made of wood, concrete, or ceramic tile. If floors are covered with
synthetic material, the relative humidity should be at least 30% to prevent electrostatic
discharges.
• Check troubleshooting.
• Consult the dealer or an experienced radio/television technician for help.
