Alarm Clock Radio announces time outdoor temperature weather and recorded messages. Just like having a personal wake-up service. When the alarm is set in voice mode it will wake you up to a "Good Morning" announcement "the time is 7:30 AM" "the temperature outside is 73.1 degrees" "the weather is going to be partly cloudy." Then it plays your previously recorded messages. Built-in Voice/Memo Center: Record up to 8 messages for total 45 seconds length; Message indicator display: Automatic message playback at time of wake up alarm; Play messages at any time: message playing function does not need an alarm to activate; Messages auto delete 6 hours after being played; Temperature/weather center displays indoor and outdoor temperature (includes 1 RF 433 MHz outdoor sensor). Weather forecast icon tells you whether to expect sun clouds or rain; arrows indicate direction of atmospheric pressure. On the radio you can preset 15 AM stations andΓ FM stations. NOTE: Weather center must be acclimated to the local area and altitude. This process takes 48 hours to set; the first weather reading will not be accurate. Dimensions: 10.25" L x 4" D x 7" H.
