Important Notice1233455789101516INDEXank you for choosing the JTS wireless system. In order to obtain the best eciency from the system, you are recommended to take a few minutes to read this instruction manual carefully.
12Please 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. PrecautionsWARNING NOTICE2. FeaturesIn 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 without permission. Users are requested to seek assistance from a qualified technician or the dealer, in case of need.TechniqueofClassDAudioPowerAmplifier• 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. PoweredbyLithiumbattery• 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-proofdesign,• enables use in severe environment*3.UPSdesign• ：when power supply in DC is inputted/removed, the unit switches to DC/Battery supply mode automatically without affecting the system operation.Energyconservingdevice:• 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. Wirelessmicrophonesystem:• 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, *6Built-inalarmsoundandLEDlighting• 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-inaudio:• 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.
