ZH4K355Bluetooth Wireless Keyboard

User Manual Bluetooth Wireless Keyboard Model Name: K355,K355A,K355B,K355C,MiniKey FCC ID: ZH4K355 FCC RF EXPOSURE INFORMATION: WARNING!! Read this information before using your phone In August 1986 the Federal Communications Commission (FCC) of the United States with its action in Report and order FCC 96-326 adopted an updated safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC regulated transmitters. Those guidelines are consistent with the safety standard previously set by both U.S. and international standards bodies. The design of this devidevice complies with the FCC guidelines and these international standards. Use only the supplied or an approved antenna. Unauthorized antennas modifications, or attachments could impair call quality, damage the phone, or result in violation of FCC regulations. Do not use the phone with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor burn may result. Please contact your local dealer for replacement antenna. BODY-WORN OPERATION: This device was tested for typical body-worn operations with the back of the iphone5 kept 1cm from the body. To comply with FCC RF exposure requirements, a minimum separation distance of 1cm must be maintained between the user's body and the back of keyboard with iphone5, Third-party belt-clips, holsters and similar accessories containing metallic components shall not be used. Body-worn accessories that cannot maintain 1cm separation distance between the user’s body and the back of the back of keyboard with iphone5, and have not been tested for typical body-worn operations may not comply with FCC RF exposure limits and should be avoided. For more information about RF exposure, please visit the FCC website at www.fcc.gov Your wireless handheld portable telephone is a low power radio transmitter and receiver. When it is ON, it receives and also sends out radio frequency (RF) signals. In August, 1996, the Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless phones. Those guidelines are consistent with the safety standards previously set by both U.S. and international standards bodies: <ANSIC95.1> (1992) / <NCRP Report 86> (1986) / <ICIMIRP> (1996) Those standards were based on comprehensive and periodic evaluations of the relevant scientific literature. For example, over 120 scientists, engineers, and physicians from universities, government health agencies, and industry reviewed the available body of research to develop the ANSI Standard (C95.1). Nevertheless, we recommend that you use a hands-free kit with your phone (such as an earpiece or headset) to avoid potential exposure to RF energy. The design of your phone complies with the FCC guidelines (and those standards). NORMAL POSITION: Hold the phone as you would any other telephone with the antenna pointed up and over your shoulder. RF Exposure Information: FCC RF Exposure requirements: The highest SAR value reported under this standard during product certification for use next to the user is 1.545W/kg. This transmitter must not be collocated or operating in conjunction with any other antenna or transmitter.
