Caution:
Charged capacitors
Before removing an instrument from its sleeve,
disconnect the supply and wait at least two minutes
to allow capacitors to discharge. It may be
convenient to partially withdraw the instrument
from the sleeve, then pause before completing the
removal. In any case, avoid touching the exposed
electronics of an instrument when withdrawing it
from the sleeve.
Failure to observe these precautions may cause
damage to components of the instrument or some
discomfort to the user.
Electrostatic discharge precautions
When the controller is removed from its sleeve,
some of the exposed electronic components are
vulnerable to damage by electrostatic discharge
from someone handling the controller. To avoid
this, before handling the unplugged controller
discharge yourself to ground.
Cleaning
Do not use water or water based products to clean
labels or they will become illegible. Isopropyl
alcohol may be used to clean labels. A mild soap
solution may be used to clean other exterior surfaces
of the product.
