Maverick R-395 Color-Coded LCD Weather Station and AM/FM Radio with Atomic Alarm Clock (Silver)

The LCD backlight remains on continuously once the unit is powered by an external adaptor and is displayed in Red when the outdoor temperature is higher or equal to 75.2°F, Amber for temperatures between 50.2°F to 75°F, or Blue for outdoor temperatures lower than or equal to 50.0°F. This clock can be powered by 4-AA batteries or with its included A/C adaptor and is designed as a free-standing unit only and cannot be wall mounted. You'll appreciate both the absolute accuracy and convenient features of the Maverick R395 atomic clock radio. For the time format, you can select 12-hour with PM, or 24-hour. Successful reception of the time-synchronization radio signal is indicated by a radio tower and waves icon above clock seconds. You can select/change your continental U.S. time zone (EST, CST, MST, or PST) at any time by means of a button on the left side of the clock. If you live in an area that does not observe Daylight Saving Time (Arizona and parts of Indiana) you can select the DST/TIME ZONE and +/- buttons to disable DST. The indoor and outdoor temperature can be displayed in either °F or °C, and both the temperature unit and the 12-/24-hour time format can be changed at any time during normal operation simply by pressing buttons on the left side of the clock. The measuring range of the remote sensor is -58°F to +158°F (-50°C to +70°C), the range of the indoor temperature is -4°F to +158°F (-20°C to +70°C). You can use the SLEEP function to let the radio lull you to sleep. The radio turns off after your preselected time, which can be 10 to 120 minutes. You can turn the radio off by pressing SNOOZE or RADIO ON/OFF. The R395 clock operates on AC120V, 60Hz house current and uses a 4-AA batterys (not included) as a power backup during ac power outages or when unplugged. The battery compartment is on the bottom of the clock. Expected battery life depends on the frequency and duration of power outages or unplugged periods.
