Key Features:

• Monitoring of Inductive Loop Systems: Ensures proper field strength and audio quality.
• Field Strength Quick Check: Displays field strength using intuitive LED indicators for easy adjustment.
• Assistive Hearing Compatibility: Includes a neck cord for users without a “T” setting on their hearing aids.
• Earphones Included: For non-hearing aid users to monitor loop system performance.
• Battery Operated: Powered by two AAA rechargeable or alkaline batteries.

Description:
The Plena Inductive Loop Receiver (PLN-ILR) is a compact and portable device designed for monitoring and verifying the performance of inductive loop systems, such as the Bosch Plena PLN-1LA10. It allows users, including those without assistive hearing devices, to check the field strength and audio quality of the loop system. This ensures that the system operates within optimal parameters, addressing issues like incorrect levels or external interference.

The unit is user-friendly and promotes accurate usage. By positioning the receiver at eye level, users naturally align the device’s coil with the plane of an assistive listening device. The included neck cord ensures correct orientation for extended usage. Its lightweight and ergonomic design make it comfortable for prolonged operation.

The receiver is attractively priced, making it a practical solution for institutions and larger facilities that require multiple units for users who lack T-settings on their hearing aids.
