MANAGING THE RECORDINGS

 

When  a  recording  is  imported  on  the  PC,  a  folder  corresponding  to  the  patient  gets 
automatically created in the 'Default root folder' defined in APIOS (see 'Tools' menu, then 
'Options').  If  a  folder  corresponding  to  this  patient  is  already  present  in  the  'Default  root 
folder', the recording is simply added to the existing patient folder.

 

The  name  of  a  patient  folder  is  composed  of  the  patient's  last  name,  first  name  and 
birthdate.

 

Thus, each patient has his/her own folder and each patient folder contains the recording(s) 
associated with this patient. The recordings are in EDF format (European Data Format) with 
'.edf'  suffix.  A  '.sor'  file  is  also  associated  with  each  recording.  This  file  contains  the 
recording's raw data and should be provided to technical support in case of problem.

 

In a patient folder, a set of files accompany the recording(s). Do not erase any of them!

 

In case of a technical problem or of a problem with data interpretation for 
which you contact technical support, it is recommended to compress the 
integrality of the patient folder where the recording in question is located 
and to send the whole folder.

 

 

To archive a recording, you have to proceed manually. On the computer, you have to go to 
the root folder which contains the patient folder, then move the whole patient folder towards 
an archive directory of your choice.

   

RECHARGING THE BATTERY

 

The device contains an internal battery. The battery is a rechargeable Lithium Polymer type 
battery. The battery is recharged via the same USB cable used for importing recordings. For 
a full recharge, connect the device to a 

USB charger.

 

In order to ensure optimal safety, please observe the rules given for battery 
in the section "Warnings and Safety Notices".

 

It is recommended to recharge the battery completely in between each recording.

 

When charging, the yellow indicator light on the front face of the selected device will start 
flashing and will keep flashing until its battery is fully recharged. A full charge takes between 
3 and 4 hours. When fully charged, the yellow light stays ON permanently. It is advisable not 
to unplug the unit while charging is in progress.
