This wireless call system supports up to 200 uniquely numbered or lettered call buttons, from 001 to ZZZ, with alphanumeric display for quick identification of service requests. It features seven distinct beep tones, ten adjustable volume levels including mute, and configurable announcement repeats. The system operates out of the box with factory settings, though custom numbering is possible via Function F1. IPX67-rated buttons and wrist watches ensure reliable performance in wet environments. Outdoor signal range extends up to 1312 feet between display and buttons, while indoor range varies based on structural interference. A remote control enables convenient operation, and optional signal boosters can extend coverage where needed. Designed for diverse care and service settings, it integrates seamlessly into clinics, nursing homes, hotels, hospitals, churches, and rehabilitation centers without requiring complex setup or ongoing maintenance.
