Microphone Placement
Place the MX890 no more than 25 cm (1 ft.) from the edge of
the table. Aim the microphone toward the talker and away from
loudspeakers and noise sources. Use one microphone for each
talker. Pickup angle with a cardioid cartridge is 130° at –3 dB.
Pickup angle with a supercardioid cartridge is 115° at –3 dB.
Note: To minimize RF interference, maintain a distance of at
least 0.3 m (1 ft.) between transmitters. In case of interference,
increase the distance between transmitters or change channels.
Receiver
Make sure the receiver is within sight of the transmitter. Do not
place receiver behind a metal barrier or any reective surface.
Refer to the SLX Wireless System User Guide for more
information, or visit www.shure.com.

Make sure the Group/Channel settings for each transmitter-
receiver pair are identical.
Make sure there is an unobstructed line of sight between the
transmitter and receiver.
If necessary, reposition the receiver or decrease the distance
between transmitter and receiver.
Remove local sources of RF interference, such as computers
or lighting equipment.

Frequency Selection
Shure offers wireless systems in a selection of bands that
conform to the different government regulations of specic
nations or geographic regions. These regulations help limit radio
frequency (RF) interference among different wireless devices and
prevent interference with local public communications channels,
such as television and emergency broadcasts.
The system’s band and frequency range are identied on the
receiver and transmitter. For example, “H4 518-578 MHz.”
For information on bands available in your area, consult your
local dealer or phone Shure. More information is also available at
Shure’s website (www.shure.com).
Licensing of Shure wireless microphone equipment is the
user’s responsibility, and licensability depends on the user’s
classication and application, and on the selected frequency.
Shure strongly urges the user to contact the appropriate
telecommunications authority concerning proper licensing, and
before choosing and ordering frequencies.
Changes or modications not expressly approved by Shure
Incorporated could void your authority to operate this equipment.

Note: This radio apparatus may be capable of operating on some
frequencies not authorized in your region. Please contact your
national authority to obtain information on authorized frequencies
for wireless microphone products in your region.

The Master List is an index of all frequencies in a band, including
those not assigned to a Group or Channel. The Master List can
only be accessed through the receiver, so the transmitter must
be synchronized via the IR port. When a Master List frequency is
in use, “MASTER LIST” appears on the display. Refer to the SLX
Wireless System User Guide for more information.
Note: Wireless devices such as cellular phones and two-way
radios may interfere with wireless microphones. Keep these and
other potential sources of interference away from the transmitters
and receivers.
