Telefunken DELTA PRO Bedienungsanleitung Seite 5

Start-up
Before using the DELTA PRO for the first time, charge it fully. For your safety, always use a suitable 5V
charger or adapter. Do not use fast charging adapters, as their higher voltage could damage the
product. The supplied USB-C charging cable is designed for use with this mobile speaker. Please only
use it to charge this device.
Connection
• Ensure that the speaker is switched off before charging.
• Connect the supplied USB-C cable to the USB-C socket on the speaker.
• Connect the free plug of the charging cable to a USB charger. Please refer to the operating
instructions for the USB charger you are using.
Charging process
During charging, the speaker's LED charging indicator lights up red continuously. The speaker can still
be used while charging. It can take up to 3 hours for the battery to fully charge. If the speaker has not
been used for more than 6 months, fully charge the battery before use.
Automatic switch-off
The device switches off automatically after 10 minutes if there is no Bluetooth connection. If Bluetooth
is connected, the device remains switched on – even in pause mode and regardless of the operating
mode.
Battery status and shutdown behaviour
An acoustic warning signal is emitted when the battery level falls below 20%.When the battery level
falls below 10%, the loudspeaker switches off automatically to prevent deep discharge.

Ensure that your device is switched on and Bluetooth is activated. The speaker and the device should
be no more than 1 metre apart for pairing.
