Frequently Asked Questions
- How much amplification does it provide?
- Up to 50 dB of call boost with a 112 dB ringer — figures aimed at significant hearing loss, not mild. There are also 6 tone settings and noise reduction. Raise amplification gradually to a comfortable level rather than starting at maximum.
- What is Slow Talk?
- A feature that slows down fast callers in real time. It addresses a common complaint that volume alone does not fix: speech that is loud enough but comes too quickly to follow. Combined with the tone settings, it targets clarity rather than just loudness.
- What kind of phone line does it need?
- A landline or VoIP phone line — it is not cellular. It is a cordless system, so it also needs an outlet, which means it will not work during a power outage. It expands to 6 handsets and is hearing-aid compatible (TIA-1083).
- Does it handle missed calls?
- Yes — there is a built-in answering machine plus call block, and talking caller ID announces who is calling. Big backlit buttons and a large LCD round out the accessibility side.
