1. 	Turn OFF the power.
2.	Press and hold the [0], [-] and [+] buttons down simultaneously  
while turning ON the power.

The OS is on EPROM. I don't think Yamaha even supplies it any more.  
All but the earliest AN1x models have 1.0.3 or 1.0.4 - all that is  
fixed between those two versions is the erroneous "low voltage"  
battery warning that can crop up now and then. Otherwise they are  
identical.
