g) Choice of sampling frequency.
Possible values are 8 kHz, 16 kHz, 24 or 32 kHz. The
higher sound sampling frequency value, the higher quality of the sound written-down, how-

h) Sound resolution.
The voice recorder can record in three formats:
16 bits under u-law
compression
,
16 bits without compression
,
20 bits without compression
. Use of u-law
compression allows to significantly increase record duration and by two/tree times decrease
memory consumption on the microSD card in comparison to the record modes in a format
16/20 bits without compression.
i)
Switching on/off logger
. When logger is switched on, all main events will be saved into
internal memory of voice recorder with their time and date. There is also voice recorder pro-
duction data stored (Identification number and number of the internal software). At normal
