USING THE UNIT SAFELY
The band has a width of 7 mm.
Use this for adjusting the head tension.

When adjusting, use the tuning key supplied with the FD-8.
• On the PD-85BK, adjusting the head tension affects only
the head response, and does not change the pitch of the
sound, as it would on an acoustic drum.
• The head tension will change as the instrument is used,
so you should readjust when necessary.
• The head stretches when used for extended periods, so
even when this is adjusted to 7 mm in the following
procedure, you may not achieve the same degree of
tension as when the head was initially adjusted. Strike
the head to check the feel and response as you adjust the
tension.
1.
Use the tuning key supplied with the FD-8 to
tighten the tuning bolts.
Tighten the bolts until there is a space of
approximately 7 mm between the frame and the
hoop.

A black, 7 mm strip is printed at the edge of this page.
Use this as a reference when making the adjustment.
Tighten each tuning bolt one by one, observing the
numerical order shown in the diagram.
Do not firmly tighten a single tuning bolt by itself. Doing
so will make it impossible to tension the head evenly, and
will cause malfunctions such as failure to accurately
detect the striking location.

Fine-tune the adjustment while continuing to
check the pad feel and response.

The PD-85BK is shipped from the factory
with the head tension loosened. Be sure to
adjust the tension before use.
In general, a tension that produces a strike response
approximately the same as an acoustic drum will be
appropriate.
•
Striking the head when the head tension is loose
may damage the sensor and head.
•
Should you neglect to make the appropriate
settings, you could likely experience the
following problems:
Sometimes it does not sound (uneven volume).
The volume is too low (reduced sensitivity).
