FCC Notice
NOTE: This equipment has been tested and found
to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against
harmful interference in a residential installation. The
equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. However, there
is no guarantee that interference will not occur in a
particular installation. If this equipment does 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 equipment
and receiver
• Connect the equipment into an outlet on a circuit
different from that which the receiver is connected
• Consult the dealer or an experienced radio/TV
technician for help
Changes or modifications to this equipment not ex-
pressly approved by Lectrosonics, Inc. could void the
user's authority to operate it.
Industry Canada Notices:
Operation of this device is subject to the following two
conditions: (1) this device may not cause interference,
and (2) this device must accept interference, including
interference that may cause undesired operation of the
device.
This device has been designed to operate with the
antenna listed below, and having a maximum gain of 6
dB. Antennas not included in this list or having a gain
greater than 6 dB are strictly prohibited for use with
this device. The required antenna impedance is 50
ohms.
Lectrosonics P/N: AMJR-915
To reduce potential radio interference to other users,
the antenna type and its gain should be so chosen that
the equivalent isotropically radiated power (e.i.r.p.) is
not more than that permitted for successful communi-
cation.
