This Wireless Solo Call System with Chair Mat can pick up an alarm signal within a 30-metre range to alert a caregiver or relative when a movement from a bed or chair is detected.When activated, the pager can be set to beep, vibrate, or both, as well as flashing. There is also a broken link indicator light if contact is lost or the pager moves out of range of the transmitter. The pager has a volume level of 85dB, a USB docking station with cable, and a rechargeable, internal battery. The transmitter can be set to alarm instantly or with a two second delay to help avoid false alarms. Two AAA batteries are needed for the transmitter but are not supplied as part of the set.
