What is Noise Cancelling?

Noise Cancelling microphones cut out up to 75% of background noise around you, suitable for open - plan work areas.

What if I haven't a headset socket on my phone?

You have two options:

  1. a) Replace your existing phone with a phone that has a headphone socket and the headset of your choice.
  2. b) Keep your existing phone and purchase an Amplifier Adapter and the headset of your choice

Amplifiers: what are they and why or when might I need one?

Amplifiers allow you to increase the volume of both, incoming and outgoing voice levels thus matching your headset to the particular phone / system or line you are using.

In addition they allow the selection of either the telephone handset or the headset (Headset/Handset switch). Most also have a mute switch which prevents the incoming caller hearing any private conversation you may wish to have during a call. Most amplifiers are operated by "AA" batteries which normally last approx 6/9 months. Some models can be used with a mains adapter if required.

An Amplifier is needed when connecting a Headset to your existing telephone either on a domestic telephone line or on a telephone system assuming there is no dedicated headset socket on the phone.

All Telephone Systems can be matched, with either an Amplifier Adapter, or programming the Telephone System to accept a Headset.

No. Only the base station gets plugged into the phone socket. The remaining handsets only require an electricity supply.

CLI stands for View Call Information via the LCD such as the name or number (or both) of the person calling. (Note some cable networks do not provide CLI)

What is the range on most cordless phones?

Most cordless phones have a range of up to around 300 meters outdoors and roughly 50m indoors. However, this depends on the building that the phone is being installed into and in our experience this range can be much less. Repeaters (boosters) can be used on most phones to extend the range.

What is the intercom facility?

The intercom facility allows you to communicate handset to handset. Intercom calls can be done from either handset. Automatic intercom activates the other unit for the use of baby monitoring. However in our experience phones do not make very good baby monitors.

Yes –You are able to transfer calls from one handset to another and you can even initiate a 3 way conversation. Not all models are capable of this so be sure to call us if you have any questions.

What’s the difference between digital and the (older) analogue phones?

As with analogue phones, digital phones still transmit on a radio frequency but suffer from less interference. Conversations are clearer and their range is usually wider. They’re sometimes referred to as DECT phones, which stands for Digital Enhanced Cordless Telecommunications.

Digital telephone and handset

What extra features can you get on them?

Lots! The most useful benefit is that you can use up to 6 handsets from the same base unit; for example, use one phone in the hallway, another in the bedroom, etc. You still have the base unit, which connects to the phone socket, but the other handsets just need to run off a mains socket.

Most digital phones are also ‘GAP compatible’, which means you can use any compatible handset with any base unit: e.g. a Panasonic GAP handset will work with a BT GAP compatible unit.

Some let you send SMS (text) messages to other SMS-compatible phones, including mobile phones. You can even call contacts from your mobile phone. Other features can include a longer battery life, out-of-range indicator, choice of ring tones, hands-free calling – even Caller ID, which lets you see who’s calling before you answer.

Most of the time, yes. You may, however, be able to use a number based anywhere in the world. For example, if you are abroad you could use a UK dialing code, so your friends in England would avoid calling international numbers and vice versa.

Yes. Since it is connected to your PC you can take it wherever you go in the world and it will always perform.
