How to use

Place the Telekom Sinus 12 base station on a stable desk surface near your analog telephone line connection and power source. Charge the handset according to the supplied instructions until the battery indicator shows full.

Make and receive calls using the handset keypad; activate the speakerphone during a call by pressing the dedicated speakerphone key for hands-free conversation. Keep the handset within the recommended indoor range for optimal signal quality.

Recommendations

Position the base station centrally within the home to maximise indoor coverage; avoid placing it near large metal objects or other devices that can cause interference. For reliable outdoor use, remain within the stated outdoor range and ensure clear line-of-sight when possible. Regularly back up important contacts manually and keep the handset charged to maintain uninterrupted availability.
