Looking for user manual or help for a Pyrod av1500 receiver

[grant67]

Hi all
Have a Pyrod av 1500 surround receiver with no remote and user manual so I'm having trouble trying to change the speaker configuration from 5.1 to 2.0 as I want to only run 2 x speakers from this amp. Trying to use the functions on the actual amp only gets me so far not sure how to go any further. I push the mode button until it flashes bypass and above it also flashes edit but that is as far as I can get. The actual amp is setup in "centre mode wide" and all I want is for it to be setup as LS & RS? Can anyone help with a user manual or manually setting up the amp.

Thanks
Grant
