The MicroAlert is important protection for all pacemaker users, those sensitive to RF radiation from TV or cell phone broadcasts, or anyone who lives or works in the presence of microwave or RF hazards. Can even be used to detect audio and video transmission from concealed bugs or the unauthorized use of cellular phones! <P align=justify> MicroAlert will respond to as little as 0.1 &#181W/cm² in highest sensitivity mode. When MicroAlert is moved closer to the source of RF radiation, the chirps will become more frequent, and will become a solid tone when exposure is high. Responds to frequencies from <U>500 kHz to 3 GHz</U>, although response is not flat over this range. What this means is that at any given setting, the threshold will vary with frequency. Note: This is not a high precision meter. Sensitivity information is only a guideline. <P align=justify> The beeping alarm threshold can be adjusted from no threshold (constant beeping regardless of radiation exposure), to to a maximum of about 10 microWatts/cm². It is intended to be an alarm for cell phones, cell towers, microwave ovens, surveillance bugs, and most RF transmitters. <P align=justify> Only 1-5/8" x 2-1/4", the 1 oz. MicroAlert uses one Lithium coin cell #2032 which should last about 3 years with normal use.
