The VRS750 does not function without CPS programming and is not pre-programmed at
the factory. To ensure operational compatibility from one unit to the next within the
fleet, all of the ASTRO Mobile and VRS750/VRS-EP systems should be programmed the
same way.
Special Programming Notes
The VRS button can be located in any of the indicator button positions normally used for
option buttons.
The VRS750 option can be enabled/disabled by a vehicle interface port (VIP). Use the
VIP Control of VRS box in the Radio Configuration->Radio Wide->VRS window
(see Figure 6) to enable VIP control and to select whether the input control is active open
or active closed. Then use the Radio Configuration->Radio Wide->Radio VIP
