the host ROS firmware as the “VOX ON” and “VOX OFF” soft menus. “WHISPER ON” and “WHISPER OFF”
soft-menus also exist—however they are not referenced in the RSS or CPS software releases. These are
possibly SP features for certain customers.

CPS programming screens.
Another miscellaneous but noteworthy firmware mention is the ASTRO™ Portable ASTRO25™
trunking firmware for the ASTRO Digital Saber™ and XTS 3000™. This is major version number R06.xx.xx
series firmware, and is used only in conjunction with ASTRO25™/9600bps trunking systems.
The Motorola Inc. XTS 3000™ has a signal-meter which is usually not active in the upper-right
display. However, with version R06.xx.xx host firmware installed, the signal-meter works for 3600 and
9600bps trunking systems.
As of host firmware version R06.22.00, there’s no support for AES-256 or triple-encryption-
algorithm modules. Only the first two algorithms are displayed during SERVICE test mode. This limitation
applies only to this major firmware revision (R06.xx.xx) and not R07.xx.xx releases.
