great for the price

January 12, 2014

Audio jack works with any 1/8" headphone jack. Has battery backup, not mentioned in specs. Projection shows outside temp and time. Radio display shows inside and outside temp and time, also alarm times are shown if alarm is on. Uses 5 volt ac adapter. Radio display can be set for high, medium, or low brightness or off. Good sound and good reception. No station presets and no alarm choices ( m-f,sat,sun) Just on off. Finally; put the batteries in the outside sensor before plugging in the radio or the radio won't find the signal, then you will have to unplug the radio tnen plug it back in so that the radio will find the sensor signal. i thought the sensor was bad until i did this. Have had radio for 3 days.

Is there a way to invert the projected image? The time projects upside-down/backward on the ceiling, which is annoying.
