2.6.2  -XV Option Specifications 
Consult factory for -XV option specifications. 
2.6.3  -HF Option Specifications 
The -HF option extends the maximum available output frequency from 819 Hz to 
905 Hz. Some restrictions are in effect at this increased output frequency level. 
All other specifications of the MX45 system remain unchanged if this option is 
installed except as noted in the table below.
