This Wireless Solo Call System with Mat alerts caregivers or relatives when it detects movement from a bed or chair.The transmitter comes with a wall mounting bracket and can either send an alert immediately it senses that someone has left the mat, or with a two second delay to help avoid false alarms which could be caused by the user moving around in bed. The pager can pick up an alarm signal within a 30-metre range and has a choice of audio alert, vibration alert, or both. A light on the pager also flashes when there is an alert, and it also has a broken link indicator so that the caregiver knows if contact with the transmitter has been lost or is out of range. The pager, which has a volume of 85dB, is supplied with a belt clip, a USB docking station, a 1150mm (45\") cable and an integral rechargeable battery. The transmitter requires 2xAAA batteries which are not supplied.
