Please read the User Instructions carefully before use. •
Please keep the User Instructions properly. •
Never place the device near a heat source, such as an oven, electric •
heater or other heating facility, so as to avoid the hazard of fire.
Never let the device in a moist, dusty environment of use for •
prolonged period; otherwise, it is likely to cause short circuit in the
device.
Do not continue to use the product under weather with lightning •
in order to prevent lightning strike which would cause injuries to
persons or damages to the device.
Store the device in appropriate places, preventing from accidental •
drop, which would cause injuries to persons or damages to the device.
Never continue to operate the device when an anomaly arises in its
operation. Turn off the power immediately and contact the distributor
as soon as possible.
1.Smoke or smell of burn comes from the device;
2.Water or any liquid flows into the device;
3.The device actuates abnormally due to accidental damage;
4.The device operates with abnormal noises or the speaker does not
sound;
5.The sound is distorted out of tune.
Keep the socket or plug of the device clean at all time to avoid excessive
built-up dust, which would otherwise tend to cause poor contact in the
device or lead to fire from wire overload.
Careful use of cord•
1. Do unplug the plug by holding its head instead of the lead to
prevent broken cord, which would result in a fire.
2. Do not cut or wind the cable, as such behavior tends to damage
the cord. Place the cord flat in a ventilated place with flammable
objects at a distance.
Go green. Do not dispose of the battery indiscreetly. Make a habit •
of recycling.
1. Precautions
WARNING NOTICE
2. Features
In order to reduce the risk of fire or
device damage, do not put the device in
high-temperature or moist environment
for prolonged period. Also, do not use
this product under weather with lightning.
To reduce the risk of electric shock, do
not remove the housing from the device

TechniqueofClassDAudioPowerAmplifier
•
The amplifier of WA-35 uses the up-to-date technique of Class D Audio Power
Amplifier, able to provide higher efficiency in power use for the system as well
as offer outstanding audio output.
PoweredbyLithiumbattery•
The system incorporates 14.8V lithium battery*1, able to provide the system
with higher output power and reduce the unit weight by about 30%, enabling
the use by carrying for long hours. Continuous music playback can last 7 hours;
continuous voice speech can last 10 hours*2.
Splash-proofdesign,• enables use in severe environment*3.
UPSdesign• ：when power supply in DC is inputted/removed, the unit switches
to DC/Battery supply mode automatically without affecting the system operation.
Energyconservingdevice:• when the sound source devices are not in use*4, the
system automatically switches off the amplifying circuit, which saves 60% of the
energy, effectively lengthening the standby time of the system.
Wirelessmicrophonesystem:• incorporates a built-in wireless microphone system
with UHF band, which works with Mh-35 handheld wireless microphones
(powered by one single AA cell) to provide 100M non-interfered transmission
and 16 channels to choose from.*5, *6
Built-inalarmsoundandLEDlighting•
Provides SOS visual call for help, lighting and two types of pre-recorded
alarm sound which is suitable for use in school or other application in
emergency evacuation.
Built-inaudio:• supports music playback via USB/SD, and 20 programmable
channels of FM radio stations.
※Notes:
1. The system operates on 14.8V power supplied by lithium battery which is 16.8V fully charged. When
the battery is below 12V, the system switches off forcibly to avoid over-discharge.
2. The above-stated time of device use are for reference only. They vary according to the volume
adjustment.
3. The description refers to spills which may happen in everyday life.
4. Sound source devices refer to “wireless microphone system”, “built-in audio” and “input from
microphone with cord”.
5. The low power radio device has passed the type approval; any firm, vendor or user may not tamper
with by changing its frequency, amplifying its power or altering its originally designed features and
functions without permission.
6. The use of low power radio device may not affect aviation safety or interfere with legal
telecommunication. The use should be stopped immediately when any interference is found; no
use may be resumed until interference is eliminated by improvement. The above-mentioned legal
telecommunication refers to radio communication operated under telecom regulations. The low power
radio device tolerates interference from legal telecommunication or radioactive devices for industrial,
scientific and medical use.

7. Important notice on product
Please make sure to recharge the battery for 8 hours before the initial use.•
It is advised to keep the battery in workable condition at all times in order to •
avoid recharging a dead battery.To ensure best function and optimal time of use,
it is recommended to recharge the device before using each time.
If the device is not in use for a prolonged period, recharge the battery on regular •
basis (or every 3 months) to prevent reducing its service life.
Please remove the battery (Fig.2-4) and contact the dealer of the device in case •
of battery anomalies, such as impossible to recharging effectively or obvious
reduced time of service, which may be a result of defective battery.
Do not put the speaker too close to a person’s ears when operating the device •
in fear of impairing his hearing with high volume.
Use soft cloth with clean water or mild detergent to clean the device. To avoid •
causing damage to the device’s surface or printed characters falling off, do not
use alcohol or any other chemical solvent.
Use the transformer supplied as accessory to the product when drawing on DC •
power, or it is recommend to use a transformer of the same specification and
safety certified as power supply kit.
When using the LED lighting, do not look directly at the light emitted, as the •
light intensity is high.
Remove the battery if the device will not be used for a prolonged period, so as
•
to prevent battery fluid leakage which would damage the transmitter.
To avoid howl from the device due to feedback, do not place the transmitter •
close to the main unit or the speaker when the main unit is set at high level of
volume.
Make sure to adjust the transmitter and the main unit at the same frequency •
when using the device.
