Before power on the board select a mode through jumper REC MODE - RUN MODE Onboard MIC will automatically be used for recording. Sampling rate is fixed with Resisters Power on the board now. Let us assume message mode 8 was selected above. This will give us 8 messages of approximately 5 seconds each message at 6 KHz sampling rate. Put the Jumper (REC mode) to Record Mode. The record mode is indicated by a Buzzer beep sound in Speaker Itself While in record mode press SW1 to SW8 to select a message segment to record the message. Let us assume we want to record message1, so we will press SW1 and will keep it press. Now whatever we speak will be captured by MIC and recorded. The LED D2 next to the IC will blink in record mode indicating that chip is currently recording. Once duration in full the LED will stop blinking means that segment is full. The SW1 switch can now be released. If before the duration is full this switch is released, then that many seconds are recorded and rest duration is kept empty.
