IMPORTANT SAFETY INSTRUCTIONS
Verify Line Voltage Before Use
The JBL CINEMA SB270 (soundbar and subwoofer) has been
designed for use with 100-240 volt, 50/60 Hz AC current.
Connection to a line voltage other than that for which your product
is intended can create a safety and re hazard and may damage
the unit. If you have any questions about the voltage requirements
for your specic model or about the line voltage in your area,
contact your retailer or customer service representative before
plugging the unit into a wall outlet.
Do Not Use Extension Cords
To avoid safety hazards, use only the power cord supplied with
your unit. We do not recommend that extension cords be used with
this product. As with all electrical devices, do not run power cords
under rugs or carpets, or place heavy objects on them. Damaged
power cords should be replaced immediately by an authorized
service center with a cord that meets factory specications.
Handle the AC Power Cord Gently
When disconnecting the power cord from an AC outlet, always
pull the plug; never pull the cord. If you do not intend to use this
speaker for any considerable length of time, disconnect the plug
from the AC outlet.
Do Not Open the Cabinet
There are no user-serviceable components inside this product.
Opening the cabinet may present a shock hazard, and any
modication to the product will void your warranty. If water
accidentally falls inside the unit, disconnect it from the AC power
source immediately, and consult an authorized service center.
