FCC CAUTION
Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
Radio Frequency (RF) Exposure Warning
The available scientific evidence does not show that any health problems are associated with
using low power wireless devices. There is no proof, however, that these low power wireless
devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency
energy (RF) in the microwave range while being used. Whereas high levels of RF can produce
health effects (by heating tissue), exposure of low-level RF that does not produce heating effects
causes no known adverse health effects. Many studies of low-level RF exposures have not found
any biological effects. Some studies have suggested that some biological effects might occur, but
such findings have not been confirmed by additional research. 1.9GHz Wireless Handheld
Microphone, model K-SHH14 has been tested and found to comply with FCC radiation exposure
limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF)
Exposure Guidelines.
Notice
FCC ID can be found on the battery compartment of the units.

Precautions
Turn off the power supply when inside an aircraft.
The product might interfere with operational safety of the aircraft.
Do not attempt to disassemble or shortcircuit rechargeable batteries.
An exploding battery or leaking battery fluid may result in fire, injury and burns.
Avoid placing the product in unstable conditions.
Failure to do so may cause injury.
Stop operation immediately when something is wrong with the product.
When smoke goes up from the product or the smell of smoke comes from the product,
continued use will result in fire. Immediately remove the battery and the battery charger, and
contact your dealer.
Do not swing the product around on its strap.
The strap might come off, resulting in personal injury or damage to the product.

[Precautions for use]
• Operating temperature:
5 °C - 35 °C {41 °F - 95 °F}
When calculating the battery life, note that temperatures below 10 °C {50 °F} shorten the
battery duration.
• Do not disassemble the product or touch internal parts.
• Battery power is slightly consumed even when the power of this product is OFF. If the
battery is left unused, that may result in liquid leakage. To prevent this, remove the battery
from the product when unused for a long time.
• Exercise care when using the product in high places. If it falls down, it may cause personal
injury or suffer damage.
• Do not use or leave the battery in places where it will be exposed to high temperatures,
such as in strong direct sunlight, in a sun-heated car, by the fire, or in front of a stove.
• Do not touch the battery poles or contacts inside the battery cover with dirty hands.
Otherwise poor contact or noise may result. If dirty, wipe off with a dry soft cloth.
The contacts inside the battery cover tend to get dirty. Clean them regularly (about once a
month) with ethyl alcohol. Do not use solvents, such as benzine or thinner, or a metal polish.
Otherwise the contacts may become deformed or discolored, or the brass plating may come
off.
• Do not use a deteriorated or short-circuited battery. A battery in this condition may leak
fluid, overheat and cause damage.
• The product is not made to drip-proof specification. Do not use the product with the wet
hands in a place where it is directly exposed to water.
• Do not swing the product around on the neck strap. To prevent strangling, the closure of
the strap provided for hanging the product around the neck is designed to give way under
pressure. If swung around on the neck strap, the closure will open and the product will fly
away, resulting in personal injury or damage to the product.
• The product is designed for indoor use.
• Use the product in a location where it is relatively shielded from noise produced by rotating
machinery, transformers or the ignition system or automobiles.
• Do not place the product on top of heatgenerating equipment, such as powered amplifiers,
video monitors or measuring instruments, and do not leave it in a closed car in hot summer.
When storing the product, do so in a dry place.
• The product is high-precision adjusted; exposing it to strong impact or dropping it on the
floor may change its characteristics. Handle the product with due care. Do not expose the
product to shock or impact as this will cause the audio output of the receiver to give off noise
on impact.
Product care
• Clean the power source with a dry cloth.
• Do not clean with volatile liquids such as benzine and thinner.
• When using a chemical cloth for cleaning, observe the cautions provided with that product.
Useful hints
• Noise prevention
Turn off the power of this product, and turn down the volume of a powered amplifier, mixer,
etc. before replacing, removing or inserting the battery, as this might produce a large noise
from these devices.
• Volume control
When the volume control from this product goes wrong, move closer to the receiver and
then try again to adjust the volume.
