Modern look and straightforward design
From its contemporary look to its intuitive operability, the Gigaset C300H scores in all categories. Its ergonomic keypad made of high-quality materials makes dialling comfortable. Reading and navigating the menu are convenient, thanks to the 1.7” large colour display with big-sized font. You can choose your favourite look for the Gigaset C300H’s display by choosing from four possible colour schemes.

Cordless freedom
The Gigaset C300H allows you to talk as long – and as frequently – as you wish. With the long talk time of up to 20 hours, you won’t worry about the handset’s battery life while you chat. And with the long standby time of up to 300 hours, you can keep the handset out of the base station, ready by your side, with little recharging necessary. A high-performance handset, the Gigaset C300H offers true cordless flexibility.

The brilliant sound quality of HSP
Hear the difference of High Sound Performance with every call you make on the Gigaset C300H. HSP works even when you talk hands-free, so that you will hear conversations clearly while you multi-task. You can easily adjust the volume by referring to the 5-step volume control. In addition, the Gigaset C300H is an HDSP-ready handset(2), which means you can register it to a Gigaset IP base station or gateway with DECT for internet calls with exceptional sound.

Convenient technical features
With the Gigaset C300H, you enjoy technical features that provide everyday practicality. You’ll always know who rings while you are out, thanks to the function that lists caller ID(2) and time. Anonymous call silencing allows you to avoid unidentified callers. The phonebook for up to 250 names and numbers let you store your favourite contacts and reach them in a matter of seconds. With the Gigaset C300H, you can also send text messages with up to 160 characters.

ECO DECT: Pure energy savings and radiation-free(5)
The energy-saving power supply of the Gigaset C300H consumes less than 0,1W(3). Like all Gigaset cordless handsets, 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 C300H’s base station by 80%(4) simply by selecting the ECO Mode. Furthermore, radiation-free(5) ECO Mode Plus turns off the transmitting power when the handset is in standby.

(1)The DECT transmitting power is switched off when handset is in idle mode – when all registered handsets support ECO Mode Plus
(2) Dependent on country/network/operator
(3) when in standby and not charging
(4) For all registered handsets – in comparison to when ECO Mode is not activated and to our conventional cordless phones
