Using the Mute All Button to Format Media 

You should always 
format your Compact 
Flash media in the 
8TraXX before using it 
for the first time.  

Formatting erases all 
sounds that may be in 
the media. 

The Mute All button is also used to format the Compact Flash media.  To format the 
media, hold down the Mute All Button during the entire power-on cycle, when the 
Channel Status LEDs are flashing. THIS WILL ERASE ANY SOUNDS STORED 
IN THE MEDIA. After boot-up is complete, the Unit Status LED activates 
indicating that the media is being formatted.  Formatting is complete when the Mute 
All LED illuminates.  

 

 

Unit Status LED 

This LED is primarily used to indicate media activity. It illuminates whenever the 
Compact Flash media is being accessed.  The LED is also used for error indication 
(refer to error indication section below). 

Error Indications 

The Channel Status LEDs and Unit Status LED on the 8TraXX are used together to 
indicate various error conditions.  The following table provides a key to the possible 
LED behavior combinations and the corresponding error or unit status that is 
indicated.
