Summary
A maker's brochure for a digital radio system for tours, conferences and assistive listening, in the 863-865 MHz band in Europe and 926-928 MHz in the US.
Key findings
- Describes a digital system (2 FSK modulation) for visitor guidance, conferences and assistive listening, operating at 863-865 MHz, or 926-928 MHz in its US version.
- Says it runs in a "license-free ISM frequency band" that "can be operated world wide", and is therefore quick to set up "without elaborate frequency planning".
- Gives 6 channels in tour-guide mode and 8 in conference mode.
- Says hearing aids can be connected for assistive listening in theatres or opera houses, with a bodypack receiver used with headphones or an induction neckloop for hearing aids with a telecoil.
- Gives the receiver's frequency response as 100-7,000 Hz.
Limits
A marketing brochure with no test data. Its description of 863-865 MHz as a worldwide licence-free ISM band differs from the CEPT entry for that band, which is shared with radio microphones and depends on national rules. No date is printed; the year is the file's creation date (17 May 2019).
