❏ 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 4
