Like all Gigaset cordless phones, it variably reduces the transmitting power from the handset to base station depending on their distance apart. You can also reduce the transmitting power of the Gigaset A510 IP’s base station by 80% simply by selecting the ECO Mode. Furthermore, radiation-free ECO Mode Plus turns off the transmitting power when the phone is in standby.

Good Quality Phone

By: on 22 March 2019
The Siemens Gigaset A510A replaced my parent's older cordless phone (another brand) that had static problems. It was easy to set up, my parents are in their late 70's and they found it easy to use. They were also very happy with the clear sound.

Since purchasing this article a couple of weeks ago, we have been very pleased with the performance especially the microphone capacity. Previous phones of other brands have let us down very badly with the quality of their microphones which has made it impossible for us to hear and the callers. We think the features are good as well.
