The influence on the environment of radio wave radiation
❏The Radio Frequency module that can be installed in this product radiates the same high
frequency energy as some other high frequency devices but the level of the energy radiated
from it is suppressed so that it is much lower than the electromagnetic energy radiated from
radio equipment like cell phones.
❏Under some situations and in certain environments, the use of this equipment is sometimes
limited by the owner of the building or a representative with responsibility for the group.
For example, it may be restricted in the following case:
• Use in an environment where it may cause interference with other devices and services.
❏If you do not understand the radio device usage policy in a specific group or environment,
such as an airport, ask permission before turning on the power of this product.
Note about interference
❏The Radio Frequency module that can be installed in this product generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
❏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 to which the
receiver is connected.
• Consult your dealer or an experienced radio/TV technician for help.
❏Never disassemble or modify this product or the installed Radio Frequency module.
❏Seiko Epson Corporation shall not be liable for interference to radio/TV resulting from
changes or modifications to this product or the installed Radio Frequency module not
expressly approved by Seiko Epson Corporation.
❏Other radio equipment sometimes uses the same frequency band that this unit uses. To
prevent radio wave interference with other radio equipment, pay attention to the following
matters when you use this product:
• The Radio Frequency module that can be installed in this product uses the Industrial
Scientific and Medical band (2.4 GHz), DS-SS modulation, and the interference distance
is 40 m.
