5. The Console (6) requires four “D” batteries (not
included); alkaline batteries are recommended.
IMPORTANT: if the exercise cycle has been
exposed to cold temperatures, allow it to warm to
room temperature before inserting batteries into
the Console. If you do not do this, the console dis­
plays or other electronic components may become
damaged.
Press the tab on the battery cover and
remove the battery cover. Insert four batteries into the
console;
make sure that the batteries are oriented
as shown by the diagram inside the battery com­
partment.
Then, reattach the battery cover.
While another person holds the Console (6) near the
Upright (3), connect the console wire harness to the
Upper Wire Harness (32).
Insert the excess Upper Wire Harness (32) downward
into the Upright (3). Attach the Console (6) to the
Upright with four M4 x 15mm Screws (40).
Be careful
to avoid pinching the Wire Harness.
7. Attach the Seat (12) to the Seat Post (5) with four M8
Nylon Locknuts (37) and four M8 Split Washers (36).
