3.13 Powering 
Up 
After the Guitar is connected to its device, it is ready to be powered up. 
 
 
 
 
Caution: 
Before applying power, ensure that the DC supply is within the specified range 
and that the proper plus-minus connections are in order. 
3.14  Initializing the System 
After the Guitar has been connected and mounted, the system must be set up and initialized. 
This is accomplished using the Composer, Elmo’s Windows-based software application. Install 
the application and then perform setup and initialization according to the directions in the 
Composer Software Manual
3.15 Heat 
Dissipation 
The best way to dissipate heat from the Guitar is to mount it so that its heatsink faces up. For 
best results leave approximately 10 mm of space between the Guitar's heatsink and any other 
assembly.  
3.15.1  Guitar Thermal Data 
•  Heat dissipation capability (θ): Approximately 8 °C/W. 
•  Thermal time constant: Approximately 360 seconds (thermal time constant means 
that the Guitar will reach 2/3 of its final temperature after 6 minutes). 
•  Shut-off temperature: 86 °C – 88 °C (measured on the heatsink) 
3.15.2  Heat Dissipation Data
