The encoder modulator is powered with a voltage of 12V DC. The power supply voltage must 
not  exceed  the  recommended  voltage,  which  otherwise  may  cause  irreparable  damage  to 
the device and the invalidation of the warranty. Therefore:  

● 

Do not replace power supply with a voltage greater than 12V DC.  

● 

Do not connect the device to the power if the power cord is damaged.

Avoid placing the device next to central heating components and in areas of high humidity.  
Do not cover the device with elements that obstruct the ventilation slots.  
If the encoder modulator has been kept in cold conditions for a long time, keep it in a warm 
room minimum 2 hours before plugging into the mains.  
When replacement parts are required, be sure the service technician has used replacement 
parts  specified  by  the  manufacturer  or  have  the  same  characteristics  as  the  original  part. 
Unauthorized substitutes may result in fire, electric shock or other hazards. 
Safety  check-  Upon  completion  of  any  service  or  repairs  to  this  device,  ask  the  service
