Safety Instructions 

Please read the following safety instructions 

before

 using your 

BITalino

 system with the EDA sensor to 

prevent any damages or problems with the user, test persons and/or 

BITalino

 devices. Violations of 

these instructions can lead to inferior signal quality and/or damages to the 

BITalino

 system and user. 

 

The user should always keep the device and its accessories dry. 
 

The  user  must  turn  off  the 

BITalino

  device  and  contact  Technical  Support  if  the  system  or 

accessories reach uncomfortable temperatures. 
 

The  user  should  not  use  the 

BITalino

  device  in  noisy  environments  (environments  with 

microwaves and other similar equipment). Doing so will lead to noise increase in the acquired 
signals and Bluetooth connectivity issues. 
 

The user must not use the device near the fire or in potentially explosive atmospheres, such as 
atmospheres with flammable gas. 
 

The user should only use the detection surfaces or other approved accessories purchased from 
PLUX or by a PLUX agent. 
 

The  user  should  inspect  the  sensors  on  a  regular  basis  to  ensure  that  they  remain  in  good 
working order. 
 

The  user  should  stop  using  the 

BITalino

  device  if  experience  any  kind  of  discomfort  or  skin 

irritation. 
 

Do not use the system on persons with allergies to silver. 

The user should dispose detection surfaces after using the 

BITalino

 device. Detection sur- faces 

are single-user and disposable. Reusable electrodes should be reused by the same user. Do not 
use reusable electrodes on several users. 
 

The user must not place the device in the microwave. 
 

The user must not insert objects into the holes of the device. 
 

The user should not open the 

BITalino

 device or its accessories. The repair of the same should 

be only done by properly authorized PLUX personnel.  
 

The user should make sure the cables do not obstruct the passage of people. 
 

The user should use the sensor cables with extreme caution to avoid risk of strangulation. 
 

The user should keep a safe distance between the 

BITalino

 device and other devices to ensure 

their proper functioning. 
 

The user should only send the device to repair to qualified PLUX personnel.
