This was copied from page 66 of the US edition of the Yamaha PSR-275/PSR-273 owner's manual:
Each percussion voice uses one note.
The MIDI Note # and Note are actually one octave lower than keyboard Note # and Note. For example, in “109: Standard Kit 1”, the “Seq Click H” (Note# 36/Note C1) corresponds to (Note# 24/Note C0).
Based on the quote, try transposing the drum channel by +12. If that doesn't work try transposing by -12.
