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), DSSS/OFDM modulation, and the interference distance is 40 m. • Other equipment that uses the same frequency band used by the Radio Frequency module that can be installed in this product includes equipment for industry, science and medical treatment, microwave ovens, HomeRF, and radio and other broadcasting equipment (both ones that require a license and ones that do not require a license). 1. Confirm that radio and other broadcasting equipment are not used nearby before using this product. 2. When trouble occurs, for example, if the Radio Frequency module causes problems such as radio wave interference, consult your dealer. ❏ Because not all the combinations of the printer and wireless LAN devices have been checked for operation, the operation of the printer in combination with all the wireless LAN devices is not guaranteed. Especially in the ad-hoc mode, the printer may not operate normally, depending on the combination of the device to connect with. Be sure to carry out through evaluation of the operation before use. • Examine the radio wave situation in the surrounding area before use. • Avoid using the same channel that is used in the neighboring shops where wireless LAN is used. 4

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 deter-
mined 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 con-
nected.
•
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), DSSS/OFDM modulation, and the interference distance is 40 m.
•
Other equipment that uses the same frequency band used by the Radio Frequency module that can
be installed in this product includes equipment for industry, science and medical treatment,
microwave ovens, HomeRF, and radio and other broadcasting equipment (both ones that require
a license and ones that do not require a license).
1.
Confirm that radio and other broadcasting equipment are not used nearby before using this
product.
2.
When trouble occurs, for example, if the Radio Frequency module causes problems such as radio
wave interference, consult your dealer.
❏
Because not all the combinations of the printer and wireless LAN devices have been checked for oper-
ation, the operation of the printer in combination with all the wireless LAN devices is not guaranteed.
Especially in the ad-hoc mode, the printer may not operate normally, depending on the combination
