The Personal Pager is a tactile paging system designed to signal the caregiver that help is needed for individuals with physical or cognitive disaiblities or who are bedridden. Simply push the button on the device and a smoll transmitter sends an electronic signal to the reciever notifying the caregiver. The signal can be sent up to 100 feet. The transmitter comes with a cord for wearing around the neck so that it is always handy. The receiver can be set to chime or vibrator (ideal for caregivers who with hearing disabilities or who are in noisy environments). The receiver has a clip for easy attachment to a belt. It can also be converted into an easel for tabletop display. POWER: Transmitter uses 12 volt battery (included) and receiver uses two AA batteries (not included). OPTIONS: Additional batteries can also be ordered.
