Ensuring that you never sleep through an alarm again, this clock uses a strobe light, a vibration pad and high decibel sound to awake even the soundest of sleepers. The large wired vibrating pad can be placed under the mattress or pillow to provide an insistent buzz that works in tandem with your choice of several loud alarm tones (up to 95 dB) and a small strobe light. An invaluable aid for those with hearing loss, the clock can be used in vibrate-only mode and placed on one side of the bed, allowing one person to sleep while the other is gently awakened at the pre-selected time. The unit can also be attached to a phone jack to alert you to calls when the telephone's ring may be hard to hear. The clock includes an easy-to-read oversized LCD display, and volume, tone, and vibration controls. Requires one 9-volt battery for power-loss backup. 5 H x 8 W x 4 D. (2 lbs.).
