Radio wave radiation

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 product 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 using this product.

The influence on the human body of radio wave radiation

The output power radiated from the Radio Frequency module that can be installed in this product is much lower than the radiation limit specified in the safety standard. However, it is best to avoid allowing this product to contact your body during usual operation. While using, be especially careful not to touch the wireless LAN unit.

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 product does cause harmful interference to radio or television reception, which can be

determined by turning this product 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 this product and receiver.

• Connect this product 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 product 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.

Notes on using this product

When using this product in environments where kitchen microwaves and other devices that may interfere radio waves are installed, observe the following points.

• Keep the printer away from the devices, such as kitchen microwaves, that may cause radio wave interference.

• Use channels that are away from the frequency bands that may cause radio wave influence.

• Place shields between the printer and the devices that may cause radio wave interference.

• In auto channel setting for the access point, do not select a channel in which the devices may cause

radio wave interference.

Wireless Telegraphy Act Regulations

The following acts are prohibited by the Wireless Telegraphy Act.

• Modifying and disassembling (including the antenna)

• Removing the label of conformance

Note about Security

Notes on Security when Using Wireless LAN

(Important information on customer rights (maintaining privacy)) The advantage of using a wireless LAN over a LAN cable is that, because information is exchanged using radio signals, you can easily connect to the network if you are within range of the radio signals. A disadvantage of this is that within a certain range, the electromagnetic signals can pass through barriers such as walls, so that if security countermeasures are not implemented in some way, problems such as the following may occur.

Communicated data can be intercepted

A third party may be able to receive wireless transmissions without authorization, and they could obtain personal information from these transmissions such as IDs, passwords, or credit card numbers, or they could intercept the contents of personal e-mail messages.

Unauthorized access to the network

A third party could access an individual or intra-company network without permission and carry out any of the following activities.

• Retrieve personal data or other secret information (information leakage)

• Pose as another user and send inappropriate data (impersonation)

• Overwrite the contents of intercepted data and resend it (falsification)

• Introduce a computer virus which could cause data loss or system crashes (damage)

Initially, the possibility that such problems could occur through settings concerning the security of the wireless LAN product and by using the product are decreased, because the wireless LAN card and the access point have security measures to deal with these problems. We recommend that you use this product after making security settings using your own judgment and assuming full responsibility, and with your full understanding of problems that may occur if you do not make any security settings.

Notes on Setting SSID (Service Set Identifier)

For protection of security, note the following precautions when setting the SSID.

• Change the SSID from the default setting.

• Do not set texts by which the owner can be identified as the SSID.

Notes on Setting Cryptographic Key

For protection of security, note the following precautions when setting the cryptographic key.

• Avoid using words on a dictionary as practicably as possible.

• Combine meaningless alphanumeric characters and symbols.

• Use texts consisted of at least 13 characters or more or of 20 characters or more if possible.
