Gigaset A540A Trio Digital Cordless Phone & Answer Machine

The superbly stylish new Gigaset A540A Trio is an excellent set of entry level DECT phones with integrated answer machine on the base. Benefits include outstanding range, great battery life, and exceptional sound quality; and the ergonomic white handsets come with a choice of illuminated display colours making this an ideal choice of cordless phones for those with an eye for aesthetics.

User-friendly home phones

Designed with users in mind the Gigaset A540A has been thoughtfully engineered to make set-up and use as easy as possible. Choose from 4 different colour profiles so that you can take full advantage of the beautifully large 1.8” display. User-friendly features include a Day/Night mode so that your home phone can be silenced for all but your VIP contacts (callers will be able to leave voicemail messages when night mode is active). And as with all Gigaset phones the A540A consumes less energy thanks to the efficient power supply unit. You can also reduce the transmitting power of the base station with Gigaset’s innovative ECO mode.

Crystal clear calls

Gigaset pioneered the use of DECT technology to improve the sound quality of their cordless phones, and have developed their signature sound protocols (HSP & HDSP) to ensure that you experience crystal clear quality on every call. The volume can be adjusted easily to suit the environment and there is a one-touch loudspeaker on the handset so that you can enjoy your calls handsfree.

Superior build quality

All Gigaset cordless phones are manufactured in Germany and come with their “Made in Germany” stamp of approval and a 2-year warranty as standard. Gigaset rigorously test every model to ensure that they adhere to their exacting standards and you get a phone that you can rely on for many years to come.

Why should you buy these Cordless Phones?

Gigaset cordless phones are renowned for superior sound quality, reliable range & ease of use. The Gigaset A540A delivers all of these at a price point that makes it excellent value for money.
