As an established telecommunications manufacturer, Geemarc have spent decades honing their design skills.

One of their latest models is a corded, amplified phone that is straightforward to operate and represents great value. We're proud to introduce the oCean 400 to our range.

Fully compatible with BT phone lines.

Hearing aid compatible for those hearing aid wearers using their "T" setting.

So, what features does the oCean 400 provide?

It's a simple, amplified, analogue telephone with Caller ID and Call Waiting indicators. Relax, knowing help is just a click away with five emergency numbers and an SOS call function. A large button keypad makes inputting numbers easier and less fiddly. It has a white backlit LCD screen that can be adjusted according to the environment you find yourself in and three languages to choose from, namely English, French and German. There's a vocal caller ID that speaks names and numbers as well as a vocal guide, offering phonebook options.

This phone is loud with a receiver volume of up to 30dB. It's hearing aid compatible, so it can be customised to fit with your hearing aids' telecoil setting. You don't have to use it with a hearing aid, as the extra amplification and four levels of tone control help many people without hearing aids too. A hands-free speakerphone enables you to chat to friends as you get on with your daily duties. Your contacts can be accessed via a built-in phonebook that stores up to 30 numbers with ease. The ringer volume can be increased up to 80dB if necessary, with a variety of ringer melodies to choose from. There's also a flashing visual ringer indicator to attract attention.
