PFU Limited PFU Limited 2023 August 2023 DANGER Do not get the keyboard wet with water, seawater, beverages, or any other liquids. Doing so may cause the batteries to heat up, explode, or ignite. Do not use, store, or leave the keyboard or batteries in any location subject to high temperature (such as in a place located by a re or a heater, in direct sunlight, or inside a car under the blazing sunlight), in any location subject to low temperature, or in any high-altitude location with low air pressure. Doing so may cause the batteries to leak, heat up, explode, or ignite. Do not burn the keyboard or batteries, or do not throw them into re for any reason. Doing so may cause the batteries to heat up, explode, or ignite. Do not strike a nail into the keyboard or batteries, hit them with a hammer, step on them, treat them badly causing high levels of impact, or crush or cut them by using a machine. Doing so may cause the batteries to heat up, explode, or ignite. For any reason, do not place the keyboard in a cooking appliance (such as a microwave oven), in a high-pressure container, or on an electromagnetic cooker (such as an induction heating cooker). Doing so may cause the batteries to heat up, explode, or ignite. Do not use an incorrect type of battery that may disable the protection function (for example, some types of lithium batteries). Doing so may cause the batteries to heat up, explode, or ignite. If battery leakage occurs, keep the liquid away from your face or hands. Not doing so may cause blindness or skin damage. If the liquid gets into your eyes or mouth, or gets on to your skin or clothes, rinse with clean water immediately. Also, in the case that the liquid gets into your eyes or mouth, go to the hospital. Before moving the keyboard, be sure to disconnect the cable of the keyboard from the computer. Make sure that the oor is free of any obstructions. Do not move the keyboard with the cables connected as this can damage the cables, which can later cause a re or electric shock. The cables can also hinder work, causing injuries. Do not use the keyboard while driving a car. Doing so may prevent you from driving carefully, which can cause an accident. Do not use any aerosol sprays or alcohol based sprays to clean the keyboard. Dust blown up by strong air from the spray may enter the inside of the keyboard. This may cause the keyboard to fail or malfunction. Sparks, caused by static electricity, generated when blowing o dust and dirt from the outside of the keyboard may cause a re. In areas (such as hospitals) where the use of radio waves is restricted, do not use the keyboard in accordance with the instructions in the area. There is a possibility that the radio waves may a ect electronic devices, medical devices, and implanted medical devices (such as cardiac pacemakers). This is a general characteristic of all devices that use radio waves, and is not speci c to this keyboard. When placing the keyboard on a table, make sure that the work surface is at and stable, and that none of the keyboards parts extend over the table edge, otherwise it may fall over or be pulled o the table and cause injuries or damage. To avoid injuries, do not place the keyboard in an area where small children may be able to reach. Do not place heavy objects on the keyboard or perform other work on top of the keyboard. Doing so might cause injuries or an equipment failure. Place the keyboard away from strong magnetic elds and other sources of electronic noise. Protect the keyboard against any static electricity and choose a static-free place to place the keyboard. Static electricity can cause the keyboard to malfunction. Transmission Speed via Bluetooth The transmission speed represents the speed de ned in the standard, and does not represent the actual speed. The actual transmission speed varies depending on the environment in which you use the keyboard. In the following environments, data transmission may slow down or not be possible at all:

There is a large distance, obstruction, or interference between the keyboard and a computer/mobile device. The keyboard is used near another device (such as a microwave oven) that causes interference. Regulatory Information FCC Declaration This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment o 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 di erent from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. FCC warning: Changes or modi cations not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Notice The use of a shielded interface cable is required to comply with the Class B limits of Part 15 of FCC rules. This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines as this equipment has very low levels of RF energy.

Wire the cables for this product as well as other peripheral devices carefully. If your foot gets caught in one of the cables, you may trip over or the product as well as other peripheral devices may fall over or be pulled o from high places, causing injuries or an equipment failure. To prevent children from chocking by getting the cables caught around their neck, wire the cables so that children cannot reach them easily. It is recommended that you place the keyboard and a computer/mobile device in the most open place possible. If there are obstacles (such as walls or metal plates) that block the radio waves, data transmission may not be possible, or the transmission speed may slow down. Do not use the keyboard immediately after moving it from a cold place into a warm room. Condensation may occur, which might lead to input errors. Let the keyboard dry for one or two hours before using it. When carrying the keyboard outside while it is raining or snowing, pay special attention so the keyboard does not get wet. If the keyboard gets wet, wipe it or wait until it dries. Precautions Liability Note READ THE DOCUMENTS SUPPLIED WITH THIS PRODUCT CAREFULLY BEFORE USING THIS KEYBOARD.
