Review: Ease of setup and the great loudspeaker - This phone is fantastic it’s easy to use, very simple set up the loudspeaker is nice and loud. When it rings there’s an orange glow on the top let you know it’s ringing. Up until now I’ve been using BT calling phones, supposedly for seniors but they have always been a letdown. This phone is great, great features too. Love love love👍🏾😀😀
Review: Simple and clear - I bought this for my elderly father who has hearing issues. He has found it OK for use after a bit of practice. Given that it's supposed to be for hard of hearing, the clarity and volume is not a good as we were expecting. The answer machine sounds muffled when played back and not that loud. Some improvements could be made considering the cost.

## Features

- HEARING AND VISUAL AID: This landline phone features large, easy-to-read buttons and a 2-line backlit display with names and numbers. The audio boost button quadruples the volume in one click, up to 40dB, and the ringer reaches 90dB. Compatible with hearing aids, it has call indicator lights on the base and handset. Wireless handset included.
- RECORDING ANSWER MACHINE: With 30 minutes of recording time, this answering machine is very easy to use, thanks to its practical access buttons on the base and the telephone, and its indicator light. The slow message playback makes listening clear and effortless.
- HANDS-FREE FUNCTION: Calls can be taken from the base for shared conversations or in hands-free mode (valid for wired and wireless units). The phonebook, synchronised between wired and wireless units, stores up to 100 contacts, and the voice prompts for dialled numbers make it easy for senior citizens to use.
- INTELLIGENT KEYS: This phone makes it easy to access contacts with 4 large programmable keys with photos of the corded phone or handset (A, B, C or D). You can block up to 100 numbers or restrict calls to those in the phonebook. The raised keys are intuitive and they can be set to announce the number just pressed to avoid any mis-dialling.
- SWISSVOICE EXPERTISE : Swissvoice has many years' experience in designing intuitive telephones and accessories for seniors. The brand combines ease of use with advanced technology for optimum efficiency.

## Questions & Answers

**Q: How does the Hearing aid compatibility work? Eg is it a Bluetooth connection?**
A: The telephone is hearing aid compatible and has been designed to eliminate background noise and interference when used with a hearing aid with a T-Coil function. 

I hope this helps. 
Thank you.

**Q: Is the main unit wall mountable?**
A: Yes there is a recess at the top middle to hang the unit on but just tried and the hand set falls off and not secure so I would say no
Hope this helps

**Q: Is there any way to have the phonebook sort entries from a to z?  They seem to only appear in order of addition.**
A: Not sure I think you press phonebook and then the key for the letter your contacts name begins with.

**Q: Do you need to touch a button to answer ?How easy is phone to answer ?**
A: The phone has 2 modes, one where you can pick the handset up to answer the phone the other requires you to pick the handset up and push a button to answer the call. 

Thank you
