ANNEX II:  UPGRADING FIRMWARE AND LOADING PRESETS (cont'd)

 

It is now safe to remove the top cover of your amplifier – there are four screws (Torx) along each side 

and eight on the top of the cover. Be careful not to drop any screws inside!
 

Locate the “Rescue Recovery” link CN11 – between ICs U24 and U28 on the top circuit board - and 

remove it. This will make your amplifier run in recovery mode – the original firmware version loaded at the 
factory will now be active.

 

Replace the top cover temporarily, reapply mains power and switch on. Once booted, check the 

interface is set as required and perform a program update again using the Flash Loader application.
 

The display will show an additional “R” next to the Remote Load message to show rescue mode is 

active:

 

Upon completion, the app will close.   Disconnect the power and wait for at least five minutes until 

the HT Present LEDs have fully extinguished again.

 

Remove top cover and replace the “Rescue Recovery” link once more.

 

Replace top cover and screw down, and replace the filter foam in the left hand front vent.

 

Your amplifier should now be fully operational again – no settings will have been lost in the process.
