Guide to ASTRO™ Digital Radios
Another method of obtaining information about an ASTRO Digital Saber’s™ firmware
version/revision,encryption module firmware, encryption algorithms, band-split, serial number, vocon
size and FLASHport features is to put it in service mode. This is accomplished by powering on the radio,
and pressing the “..” button on the side of the radio five times, within the first 10 seconds of
completing the SELF TEST sequence. The radio will beep once and show SERVICE on the display. It will
slowly (or quickly, depending host firmware version) scroll through this critical information. You may
repeat the process several times if the information goes by too fast.
The final, and most logical way to determine an ASTRO Digital Saber’s™ vocon size, is to
disassemble the radio. Disassembly instructions are outlined in the ASTRO Digital Saber™ Basic Service
Manual. (68P81076C05) Compare your findings with the photographs in figure 2.2 of this guide.
Despite being out of production, the ASTRO Digital Saber™ is still a favourite among radio-
hobbyists and public-safety officials for its robust design and solid RF performance.
