Serene Innovations PG-200 Two-Way Personal Pager System

Summon help with the press of a button and get the peace of mind of a reassuring acknowledgement signal indicating that your page was received. Ideal communication method for patient and caregiver; perfect for an older parent living with family. This is how it works: 1) The patient presses the large button on their pager when they need their caregiver; 2) The caregiver is alerted by vibration and strobe-light flasher or audible tone on their pager; 3) To let the patient know the page was received, the caregiver presses the large button on their pager which signals the patient's pager. Note: Either pager can serve as the sending pager to inititate an alert or as the receiving pager to acknowledge the alert. The PG-200 includes two pagers that have been factory-paired, and after charging, ready-to-use right out of the box. Up to two more pagers (PG-200R) may be purchased, added, and easily paired to your existing two-pager set, to create a four pager system.
