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 Upgrade setting set to ‘Authenticate’ (see ‘Maintenance > Upgrade’ on page 114).
The new software will have uploaded in to the Aprisa SR but will not have activated. The new software
version will be displayed in the Standby SW version.
In this case, go to SuperVisor ‘Maintenance > Upgrade’ on page 114 and tick the ‘Switch to new Software’
checkbox and click ‘Save’ to apply the changes.
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.
To view the uploaded software version:
Select Terminal Settings > Terminal > Summary
The version of the uploaded software will be displayed in the ‘Standby SW Version field.
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.
