Laboratory2, LTD
4 Logger.
Logger is designed to register history of recorder’s operation and emergencies to the non-
volatile memory.
In addition, logger contains manufacturing data (recorder identification number and
firmware number)
Logger stores from 32 to 48 latest events, as well as their time and date.
If the logger is turned on (see. 2.6 (i)) and voice recorder is switched off (except
emergency reset) logger is recorded to micro SD into the file INF_REG.TXT.
It is not recommended to use the logger continuously
since this reduces nonvolatile
memory resource of the voice recorder (it only affects work of the logger itself).
Brief description of the recorded events and the logger structure is given in Table 5.
