panel and hold it in whilst turning the amplifier on. The LIM LEDs will both

Pressing "Y" on the keyboard will then
erase the current firmware and
prompt for a new version to be
loaded.

the erase procedure, just press
any another key or turn the
amplifier off.

LED will turn green and the message

Send Text File and point the program to the
location of the amplifier firmware file.

select window is "txt" – change this to
"hex" to ensure the firmware can be
located.
