Aprisa SR User Manual
If the radio is not operating on the new software (after the power cycle), it could be caused by the
SuperVisor ‘USB Boot Upgrade’ setting set to ‘Load Only’ (see ‘Software > Setup’ on page 155).
In this case, go to SuperVisor see ‘Software > Manager’ on page 159 and tick the Software Pack ‘Activate’
checkbox and click ‘Appy’.
If any Display Panel LED flashes red or is steady red during the upgrade process, it indicates that the
upgrade has failed. This could be caused by incorrect files on the USB flash drive or a radio hardware
failure.
Software Downgrade
Radio software can also be downgraded if required. This may be required if a new radio is purchased for
an existing network which is operating on an earlier software release.
The downgrade process is the same as the upgrade process.
