Product information

User-friendly telephone with optimum features 

The Gigaset A120 ECO DECT Cordless Phone is a user-friendly and affordable telephone. Dialling is made easy thanks to sensitive pressure points on the keys and a backlit graphical display.

Ready to use

Plug and play setup and a pre-registered handset means that you can use the phone as soon as you take it out of the box.

18 hours talktime

With talktime of up to 18 hours and with the standby time of up to 200 hours, there's no need to constantly worry about recharging the Gigaset A120.Everyday calling is made more convenient with logs of the last 25 missed and received calls, the last 10 numbers dialled and a directory for up to 50 contacts.

50m range indoor - 300m range outdoor

The LED display shows the date and call duration, caller ID and even has an alarm function. This phone provides high quality digital sound, even when you are away from the base station - it has an impressive range of up to 50 metres indoors and 300 metres outdoors thanks to DECT GAP technology.


The Gigaset A120 uses an energy-saving power supply so it consumes less electricity - making it kinder to the environment and kinder on your wallet.  Like all Gigaset cordless phones, the power supply is automatically adjusted depending on how far away the handset is from the base unit and the radiation-free ECO Mode Plus turns off power when the phone is on standby.

Product Questions
I already have a Gigaset A120 with 3 phones. The phone which is on the base seems to be faulty. If I replace this can I use the existing 2 phones with the new phone and base.


It is possible to replace the faulty unit : It will still work with the two other phones, you will just need to do the pairing again as if the 2 phones were also brand new. 

Thank you
