Why won't my Doro 6620 Telephone turn on?

If your Doro Telephone won't switch on, it could be due to a low battery charge or the battery being incorrectly installed. Connect the power adapter and charge the battery for 3 hours. Full battery capacity is reached after the battery has been charged 3–4 times. Also, check the installation of the battery.
