AutoTune™ for VX-P820/P920 Rev. C
2
3. Requirements
3.1. Firmware
Before attempting to align or test a VX-P820/P920 radio, the radio’s firmware must be
version 1.29 or later. This firmware version is required to support the AutoTune™
alignment and test capabilities.
On models equipped with an LCD, the radio firmware version may be viewed by
pressing and holding the side LAMP Button key while turning the radio on. After radio
power-on and self test, the radio will enter the screen test/version view mode.
Subsequent LAMP Button presses will cycle through the following screens, in this order:
• Icon test
• Character test
• Serial number
• Firmware version/band
• DSP version
On the Firmware version/band screen, the firmware version is the 4 character value on
the left.
For models without an LCD, the radio firmware version may be obtained by using
Vertex Standard CE76 software. With the radio connected to a PC, select the Radio >
Upload command from the main menu bar. Once the radio’s information has been
uploaded, the firmware version number is displayed in the “FW Version” field.
3.2. Analyzer
Because of the P25 nature of Vertex Standard VX-P820/P920 radios, a P25-equipped
R2600 series Communications System Analyzer is necessary for full use of AutoTune™
for VX-P820/P920 radios. However, a R2600 series analyzer without the P25 option will
perform all alignments and tests except for Maximum Deviation. If Maximum Deviation
is selected for performance and the R2600 series analyzer in use is not P25 equipped,
the user will be notified and the Maximum Deviation test will be marked as Fail.
The analyzer must contain the following PROJ 25/ASTRO/SNET software version to
perform correctly:
6.04.B00 or later
