3.4.10  MAINTENANCE MESSAGES 
 

 

The commands in this message category are for maintenance operations 
only.  These commands are not intended for normal applications and may 
interact with normal operations of the tuner.  Powering the tuner down and 
back up will eliminate any of those interactions and return the tuner to 
normal operation.  The mnemonics associated with this message category 
are listed in 

Table 3-16
