RCA 26958 manual Memory Full

MEMORY FULL

When the memory is full, the system answers after 10 rings, beeps and waits for the caller to enter the 3-digit security code. If you don't enter the security code within 10 seconds after the unit beeps, the phone hangs up.

You need to erase some of the messages in order for the system to record new incoming messages.

NOTE: The unit also answers after the 10th ring if it is turned off. To access the answering system, enter your 3-digit security code after you hear the beep.
