• 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
to reset the
0
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.
