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 8) 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

window (see Figure 7) to select the VIP to be used. However, the VRS

button must still be added to the control unit if it is desired to have

the indicator light when the VRS750 is enabled. See the ASTRO Spectra

CPS user’s manual for details concerning programming the VIP.

NOTE: The ASTRO Spectra CPS user’s manual does not

indicate that the VRS button is required in order to

have the indicator light when the VIP is enabled.
