Main Features

Touchscreen features, a convenient keypad and customizable settings with two extra handsets make this phone with an integrated answering machine a high-performance companion.
For smart, cutting edge features with an integrated answering machine with space for up to 55 minutes of messages and four extra handsets choose the Gigaset S820A Quint cordless phone. All important functions are at your fingertips on the large, 2.4” touchscreen that makes reading and handling very simple. It also has a keypad for simple dialling. Handy tools include silencing of calls, blocking of anonymous numbers, and text message forwarding. Rest easy knowing that Eco Mode Plus means your phone maintains the highest environmental and radiation-free standards.

You’re in control

With the Gigaset S820A Quint, call management is straightforward. The idle screen is configurable with up to six of your favourite functions so you can access them with just one tap on the touchscreen. Should you not wish to be disturbed at certain times of day, simply program the time-based call silencing function. Silence unknown numbers or block specific numbers you don’t want to hear from for additional peace of mind. Not at home but still need to pick up calls and messages? No problem – simply forward incoming calls and texts to your mobile or another contact number. 

Features you adjust
The Gigaset S820A lets you adjust settings to suit your needs. Quick Sync and Bluetooth® technology allow you to synchronize information between the phone and, for instance, your Outlook files. Give your contacts individual ringtones and picture IDs by easily downloading sounds and pictures. With up to 500 vCard entries, you can maintain an extensive contact list – each entry provides space for up to 4 numbers.
Your life organized
The Gigaset S820A’s lists of recent outgoing, incoming and missed numbers let you quickly and easily resume conversations you had in the past with just one touch on the display. Use the phone’s built-in calendar, date reminder and alarm clock with a snooze button to ensure you are where you’re meant to be on time. The birthday reminder allows you to program contacts’ birthdates so you never forget their special days.
Talking and listening with ease
Continue conversations for as long as – and whenever – you like thanks to the Gigaset S820A’s long talk time of up to 20 hours and its extensive standby time of up to 250 hours. With two extra handsets you’ll never have to look far for a phone. The handset’s side key allows you to adjust the volume while you talk and every call benefits from the brilliant quality of High Sound Performance.

Always on
The integrated answering machine of the Gigaset S820A records up to 55 minutes of messages, for those times you are unavailable. You can comfortably operate the answering machine via handset and listen to messages in brilliant sound quality.
ECO DECT: Pure energy savings

ecodect_76The energy-saving power supply of the Gigaset S820A consumes less electricity, so it’s kinder to the environment, and kinder to your wallet. 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 S820A’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.

Great tip for busy households: increase your flexibility immensely with the new Gigaset Smart Extra, the L410 speakerphone clip. This device brings even more convenience into your household and is fully compatible with the Gigaset S820A.  The Gigaset L410 is available here.
