3.2.7.  Routine maintenance  

Maintenance only consists in cleaning outside the appliance. Any other operation requires a 
qualified personal.  

 
 

Unplug the appliance before any intervention.  

 
 

Never let water flow through the appliance to prevent any electrical discharge. Periodically 
clean the recorder with the following instructions:  
-

 

Use water and soap to clean the front and rear boards.  

-

 

Never use any product that contains petrol, benzene or alcohol: they would damage the 
screen printings.  

-

 

Wipe with a soft lint-free cloth.  

-

 

Use some antistatic product to cleanse the screen.  

 
 

3.3.  UPDATING THE INTERNAL SOFTWARE 

The internal software is updated regularly with the latest evolutions. These updates are 
available on our website.  

http://www.sefram.com/en/software-updates.html

 

 

-

 

To update the software, copy the file that will be provided on an USB stick. Place it on 
the USB connector on the rear side of the appliance.  

-

 

Press the  

“Setup”

  key.  

-

 

Then press the 

“Software update”

  key to enter the update.  

-

 

Finally, to run the update, press the 

“Sofware update”

  key.  

-

 

Then, the internal software automatically copies the necessary files to the new version.  

-

 

Turn the appliance off and on after the end of the updating process.  

 

 

3.4.  External power 

 
You can power the appliance using an external continuous voltage source. The appliance 
operates with a voltage of 15V (5 A). The charger block provided during the purchase acts 
as an external power.

Attention

:   minimize shock hazard, the instrument chassis and cabinet 

must be connected to an electrical safety ground. This instrument is 
grounded through the ground conductor of the supplied, three-conductor 

AC

 line power cable. The power cable must be plugged into an approved 

three-conductor electrical outlet. 
 

 

Attention

 :  When the charger is connected to the appliance, the metallic 

frame is linked to the ground of the electrical installation
