I don't know off hand on that radio. My guess would be to push both programming buttons up at the same time and then turn on the radio. That's how the aicraft type is selections are entered on my 662 and 8103.

Have you tried looking at Horizon's website? They have the manuals online for most, if not all, the JR radios. [link]http://www.horizonhobby.com[/link]
