Cautions Regarding Radio Wave Radiation
The influence on the environment of radio wave radiation
❏ The electromagnetic energy radiated from this product is suppressed so that it is much lower than that
of 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. 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
❏ 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, the user is encouraged
to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna for radio/TV.
Increase the separation between this product and radio/TV.
Connect the printer fitted with this product to an outlet on a different circuit from the radio/TV.
Consult your dealer or an experienced radio/TV technician for help.
❏ When using this product in environments where microwaves and other devices that may interfere
radio waves are installed, observe the following points.
Keep the wireless LAN unit away from the devices 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 wireless LAN unit and the devices that may cause radio wave interference.
Select either 2.4 GHz or 5 GHz, whichever is free from 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.
❏ Never disassemble or modify this product. Seiko Epson Corporation shall not be liable for interference
to radio/TV resulting from changes or modifications to this product not expressly approved by Seiko
Epson Corporation.

Cautions Regarding Wireless LAN Connections
❏ In the infrastructure mode, W53 and W56 channels are not available to connect to a stealth SSID access
point.
❏ Because not all the combinations of the product and wireless LAN devices have been checked for
operation, the operation of the product in combination with all the wireless LAN devices is not
guaranteed. Especially in the ad hoc mode, the product 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.
