This is their tech support's response:

Amp Section Toshiba 12 Bit Codes HEX

Code is repeated twice (50/160 msec)

VOLUME + B10
VOLUME - B20
PHONO AA0
TUNER A88
AUX1 A84
AUX2 A82
TAPE A81
CD A90
MUTE A42

I know I'm dim-witted in comparison with most of the regulars here, but how do I translate that into something I can copy and paste into PEP? Do I just translate into binary and use that? e.g. B10 = 101100010000 - that doesn't seem to work, it just shows 'invalid IR code' in the box below in the component function section when I've copied and pasted it into the box below the function list.

Any help greatly appreciated. Am happy to pay for time if someone can generate them from this.
