Erasing Voice Memos
The recorded voice memo can be erased. This operation is performed when a voice
memo was recorded while waveform acquisition was in progress, but you wish to save
the waveform data without the voice memo.
After step 16 of this section, press the
Erase
soft key. The voice memo is erased, and
the voice memory indicator value on the screen is cleared.
Note
Once a voice memo is erased, it cannot be recovered. Use caution when erasing a voice
memo.
Explanation
A voice memo can be recorded while waveform acquisition is in progress (when in roll
mode display) by connecting an earphone microphone with a PUSH switch to the DL750/
DL750P.
Setting the Mode
To enable the voice memo function, set Mode to ON.
When turned ON, a voice memory indicator is displayed at the lower right corner of the
screen.
Displaying Event Waveforms
The event waveform (Voice bit of the event waveform) indicates the record interval of the
voice memo. The interval during which a voice memo is recorded is from the rising edge
to the falling edge of the event waveform. For the procedure of setting event waveforms,
see section 5.21.

Precautions Regarding the Voice Memo Function
• If the record length setting is set long in the ACQ menu causing the number of
channels that can be used to 3 channels or less, event waveforms are not displayed.
In this case, the voice memo function cannot be used.
• If the voice memo function is OFF (Mode: OFF) even when the event waveform
display is ON (Event Display: ON), event waveforms are not saved when waveform
data is saved. In addition, even if a voice memo is recorded during waveform
acquisition, if the voice memo function is turned OFF at the time waveform data is
saved, event waveform data/voice data will not be saved.
• In realtime recording, if the valid number of channels
1
is 3 channels or less, event
waveforms cannot be used. In this case, the voice memo function cannot be used.
1. Valid number of channels signify the number of channels that are turned ON excluding
MATH1 to MATH8 channels. However, for LOGIC A and LOGIC B, the number of channels
is counted as 1 regardless of whether one of the channels is ON or both channels are ON.
