In this appendix:
Q
Adding receive frequencies for 
the 450 MHz internal radio
If you have installed the optional internal 
450 MHz radio in your GPS receiver, use the 
WinFlash utility to add the relevant receive 
frequencies to the default list of frequencies. To 
install the WinFlash utility, see
 
Installing the 
WinFlash utility, page 140.
If you have also purchased the transmit option 
(SPSx50 and SPSx80 only), Trimble must specify 
and configure the (FCC-approved) transmit 
broadcast frequencies at the factory. You cannot 
configure these yourself.
