Note: XT10 and XT20 are mechanically and
electronically identical. The only difference is in
their displays. The residential model XT10 has
user programs. The commercial model XT20
does not have user programs. For general
troubleshooting, this manual applies to XT10
and XT20.
Manual updates follow:
Version 1: 12-07-05 – Initial version
Version 2: 02-01-06 – Note below added
Note: The cover picture shows a prototype with
handles (like the C5150 bike). Production units
of XT10 and XT20 never had such handles.
