ASTRO 25 (P25) Programming Over Project 25 (POP25)
Also called Over-the-Air Programming, this feature allows configuration data and firmware to be
upgraded to your radio over-the-air. Full use of the radio is retained during the data transfer without
interrupting communication.
If the upgrade happens on the ASTRO 25 and ASTRO Conventional systems, the upgrade pauses to
give priorities to voice call, and continues after the voice call ended. If the upgrade happens on a Wi-Fi
network, the upgrade process runs concurrently with voice calls.
Once a configuration upgrade is downloaded to your radio, you can install new changes immediately or
delay changes to be installed on the radio when it is being powered up.

takes several minutes.
NOTICE: The radio cannot be used while the upgrade is being installed. Therefore, make
sure to only accept the upgrade at a convenient time when immediate radio use is not
required.
