7.5. DELETING RECORDINGS FROM CF MEMORY CARDS
To start playback press
. You will see the playback level indicator bar, playback time counter
and playback status symbols (see Table 6.1). You can control playback and invoke Gnome-2M
c
features (loop playback, speech signal search, playback level adjustment and noise-cancellation) by
pressing respective keys as described in Table 6.1.
7.4.2
Controlling playback volume, noise suppression and playback speed
In the playback mode the following functions are available:
•
volume control
•
noise suppression (in dB)
•
speed control
Parameter selection is performed with the
key (
“Volume”
for playback volume control;
“B.B.Filter”
for broadband and harmonic noise suppression;
“Composit”
for composite noise sup-
pression;
“Stretcher”
for playback speed control). To adjust the selected parameter use
on
the voice recorder keyboard. Playback volume can be changed within the range of -73+6 dB, noise
suppression for both filters is between 0 and 30 dB, speed control allows acceleration and deceler-
ation of playback tempo up to 2,5 times (in the range between 40% and 250% relative to the initial
100%).
Important!
Enabling noise suppression and/or speed control in the playback mode causes
considerable increase in power consumption. Therefore it is recommended to use external
power supply. If the device is battery-powered make sure the current batteries’ state of
charge indicator shows at least one graduation mark.

Deleting recordings from CF memory cards
You may delete records from the CF card using either the voice-recorder or the Sound Manager
software (see Section 8).
To erase all the existing records press the red button (Fig. 6.1 p.8). Enter your PIN-code (if set)
and confirm the action. All the recordings will be erased from the CF card.
To delete only some of the existing records, enter the playback mode (see Section 7), select a
record and press the
key.
Important!
Do not remove the memory card from the voice recorder until the deletion
process is completely finished. Otherwise part of the CF free memory may remain inac-
cessible, even though the recordings have been physically deleted.
After you deleted all information from the CF card, check it for available memory space:
if it is less than the initial memory capacity, reformat the card.
