i
Protect the power cord from being walked on or pinched,
particularly at plugs, convenience receptacles, and the point where
they exit from the apparatus.
j
Only use attachments/accessories specifi ed by the manufacturer.
k
Use only with the cart, stand, tripod, bracket, or table specifi ed by
the manufacturer or sold with the apparatus. When a cart is used,
use caution when moving the cart/apparatus combination to avoid
injury from tip-over.
l
Unplug this apparatus during lightning storms or when unused for
long periods of time.
m
Refer all servicing to qualifi ed service personnel. Servicing is
required when the apparatus has been damaged in any way, such
as power-supply cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has
been dropped.
n
Battery usage CAUTION – To prevent battery leakage which may
result in bodily injury, property damage, or damage to the unit,the
batteries (battery pack or batteries installed) shall not be exposed
to excessive heat such as sunshine, fi re or the like.

Hearing safety
Listen at a moderate volume.
Using headphones at a high volume can impair your hearing. This
•
product can produce sounds in decibel ranges that may cause hearing
loss for a normal person, even for exposure less than a minute. The
higher decibel ranges are offered for those that may have already
experienced some hearing loss.
Sound can be deceiving. Over time your hearing ‘comfort level’
•
adapts to higher volumes of sound. So after prolonged listening, what
sounds ‘normal’ can actually be loud and harmful to your hearing. To
guard against this, set your volume to a safe level before your hearing
adapts and leave it there.
To establish a safe volume level:
Set your volume control at a low setting.
•
Slowly increase the sound until you can hear it comfortably and
•
clearly, without distortion.
