A:Answer Hello! The manual is available online at the following website: https://help.na.panasonic.com/wp-content/uploads/2023/02/KXTGD86x_PNQX9141ZA_ENG_ESP.pdf . If you want to turn on the answering machine, you need to press the ANSWER ON/OFF button on the main base unit. Also, if you want to record your own greeting message, you need to take a handset, then press MENU, then the key # and enter code 302. After a beep sounds, speak clearly about 20 cm (8 inches) away from the microphone (2 minutes max.). and press STOP to stop recording. In the end, you need to press OFF to exit the programming mode. Hope this helps! -C
