Important!

• You can perform record, playback, and clear operations in the Timekeeping Mode, Voice Mode, or Telememo Mode. In the Timekeeping Mode and Telememo Mode voice memory contents can be played back in sequence starting from the newest recording. In the Voice Mode, you can select a specific area for playback.

• Total recording time is 30 seconds, and a full 30 seconds of recording are provided when only a single recording is stored in voice memory. A full 30 seconds of recording may not be provided when more than one recording is stored in voice memory (due to memory used up by memory partitioning).

• Once voice memory is full, you will not be able to record any more until you clear all existing data.

• It is always a good idea to check the number of recordings already in voice memory and the voice memory’s remaining capacity before starting a new recording.

• All alarms (including the hourly time signal and Countdown Alarm) are temporarily turned off while a recording operation is being performed. Any alarm that occurs during a recording operation will sound after the recording operation is complete.

• If playback produces a sound that is broken or unclear, try changing the distance between the source of the sound and the microphone. Good results can normally be obtained by speaking clearly in a normal voice with about 5cm (2 inches) between your mouth and the microphone.

The Voice Mode lets you record and playback your voice or other sounds. You can also clear recordings when you no longer need them.

• The area number shows a value from 1 to 5 that indicates the location of a recording and number of recordings currently in memory.

• The watch also has a built in speaker.

• If you do not operate any button for 2 or 3

minutes while in the Voice Mode, the watch automatically goes back to the Timekeeping Mode.

Recording Duration

The watch has enough voice memory for up to 30 seconds of sound data. You can make one recording 30 seconds long, or up to five recordings that total up to 30 seconds. Whenever you make a recording, the sound data is stored together with the date and time that the recording operation began.
