IMPORTANT SAFETY INFORMATION
Please read and retain these safety instructions carefully before using your portable
karaoke speaker. Failure to follow these guidelines could result in electric shock,
fire, personal injury, or damage to the product or surrounding property. To ensure
safe operation, observe the following precautions:
INTENDED USE ONLY
Use the speaker only as directed in the user manual and by the manufacturer. Any
improper or unintended use may lead to malfunction, injury, or voiding of the
warranty.
AVOID MOISTURE
Keep the speaker dry at all times. Do not use or store the device in damp or wet
environments. Avoid exposing it to rain, splashes, or spills.
NO LIQUID CONTAINERS NEARBY
Do not place containers holding liquids (e.g., vases, cups, bottles) on or near the
speaker. Accidental spills can lead to electric shock or short circuits.
AVOID HEAT SOURCES
Keep the speaker away from open flames, radiators, heat registers, stoves, or any
other sources of excessive heat. Prolonged exposure to heat may cause
overheating or damage.
USE APPROVED ACCESSORIES
Only use the power adapter, charging cables, and accessories supplied with the
product or officially recommended by the manufacturer. Using unapproved
accessories can pose safety risks.
MAINTAIN PROPER VENTILATION
Do not cover or block any ventilation openings. Install and operate the speaker in a
well-ventilated area to prevent overheating. Maintain a minimum clearance of 10
cm (4 inches) around the unit.
POWER SAFETY
Unplug the speaker during electrical storms or if it will be unused for extended
periods. This helps protect the device from power surges or lightning damage.
CABLE MANAGEMENT
Position power cords to avoid tripping hazards or damage. Do not allow the power
cable to be pinched, bent excessively, or exposed to heavy foot traffic, especially at
the plug or device connector.
AVOID PHYSICAL DAMAGE
Do not drop, crush, puncture, or disassemble the device. Physical damage may
compromise internal safety components and create a fire or shock hazard.
NO USER-SERVICEABLE PARTS
Do not attempt to open or repair the speaker yourself. Repairs should only be
performed by authorized service personnel. Unauthorized tampering may result in
injury and void the warranty.
CHILDREN AND PETS
Keep the speaker and accessories out of reach of small children and pets. Small
parts may pose a choking hazard, and cords can present entanglement risks.
