●  Use only the power supply unit and AC power cord that came with your device or that you received from

an authorized repair center.

●  Confirm that your electrical outlet provides the type of power indicated on the power supply unit (in

terms of voltage [V] and frequency [Hz]). If you are not sure of the type of power supplied to your home, 

consult a qualified electrician.

●  Do not use non-standard power sources, such as generators or inverters, even if the voltage and

frequency appear acceptable. Only use AC power provided by a standard wall outlet.

●  Do not overload your wall outlet, extension cord, power strip, or other electrical receptacle. Confirm

that they are rated to handle the total current (in amps [A]) drawn by the device (indicated on the power

supply unit) and any other devices that are on the same circuit.

●  Protect the power cords from being walked on.
●  Protect cords from being pinched or sharply bent, particularly where they connect to the power outlet,

the power supply unit, and the device.

●  Do not jerk, knot, sharply bend, or otherwise abuse the power cords.
●  Do not expose the power cords to sources of heat.
●  Keep children and pets away from the power cords. Do not allow them to bite or chew on them.
●  When disconnecting the power cords, pull on the plug—do not pull on the cord.

If a power cord or power supply becomes damaged in any way, stop using it immediately. Unplug your

device during lightning storms or when unused for long periods of time.
For devices with an AC power cord that connects to the power supply, always connect the power cord 

according to the following instructions:

1  Plug the AC power cord into the power supply until it stops.
2  Plug the other end of the AC power cord into the wall outlet.

These precautions apply to all products that use rechargeable or disposable batteries.
Improper use of batteries may result in battery fluid leakage, overheating, or explosion. Released battery

fluid is corrosive and may be toxic. It can cause skin and eye burns, and is harmful if swallowed.
To reduce the risk of injury:

●  Keep batteries out of reach of children.
●  Do not heat, open, puncture, mutilate, or dispose of batteries in fire.
●  Do not mix new and old batteries or batteries of different types (for example, carbon-zinc and

alkaline batteries).

●  Do not allow metal objects to touch the battery terminals on the device; they can become hot and

cause burns.

●  Remove the batteries if they are worn out or before storing your device for an extended period of time.
●  Always remove old, weak, or worn-out batteries promptly and recycle or dispose of them in accordance

with Local and National Disposal Regulations.

●  If a battery leaks, remove all batteries, taking care to keep the leaked fluid from touching your skin

or clothes. If fluid from the battery comes into contact with skin or clothes, flush skin with water 

immediately. Before inserting new batteries, thoroughly clean the battery compartment with a damp 

paper towel, or follow the battery manufacturer’s recommendations for cleanup.

●  Caution Risk of explosion if battery is replaced by an incorrect type. Use and replace only with the

correct size and type (alkaline, zinc-carbon, or zinc-chloride) of batteries.

●  Caution Risk of explosion if battery is replaced by an incorrect type. Use and replace only with the same

type and rating as the batteries provided.

●  Charge only with the recharger provided with the product.

Extended exposure to high volumes when using a headset may result in temporary or permanent

hearing loss.

Before boarding any aircraft or packing a wireless device in luggage that will be checked, remove the 

batteries from the wireless device or turn the wireless device off (if it has an on/off switch). Wireless devices

can transmit radio frequency (RF) energy, much like a cellular telephone, whenever batteries are installed

and the wireless device is turned on (if it has an on/off switch).

Health Warning
Use of a keyboard or mouse may be linked to serious injuries or disorders.
When using a computer, as with many activities, you may experience occasional discomfort in your hands,

arms, shoulders, neck, or other parts of your body. However, if you experience symptoms such as persistent

or recurring discomfort, pain, throbbing, aching, tingling, numbness, burning sensation, or stiffness, 

DO NOT IGNORE THESE WARNING SIGNS. PROMPTLY SEE A QUALIFIED HEALTH PROFESSIONAL, 

even if symptoms occur when you are not working at your computer. Symptoms like these can be associated 

with painful and sometimes permanently disabling injuries or disorders of the nerves, muscles, tendons, or 

other parts of the body. These musculoskeletal disorders (MSDs) include carpal tunnel syndrome, tendonitis,

tenosynovitis, and other conditions.
While researchers are not yet able to answer many questions about MSDs, there is general agreement that 

many factors may be linked to their occurrence, including: overall health, stress and how one copes with it, 

medical and physical conditions, and how a person positions and uses his or her body during work and other 

activities (including use of a keyboard or mouse). The amount of time a person performs an activity may also

be a factor.
