+ Unauthorized conversions and/or modifications of the appliance are not permitted for safety and licensing reasons (CE).

< The appliance is approved for operation in dry, closed rooms only. Do not operate the device nearby water, such as in bathrooms or nearby swimming pools.

e The appliance may not be exposed to extreme temperatures (< +5°C / >+35°C) in operation.

< The appliance may not be subjected to strong vibrations or heavy mechanical strain.

+ Do not place any recipients filled with liquids, such as glasses or vases, on top of or directly next to the appliance. They could fall over, causing water to enter the appliance. Never pour out liquids above the appliance. Do not place any small objects, such as coins or paper clips, on the appliance since they could fall inside the appliance. You run a high risk of causing a fire or life-threatening electrocution! If any liquid or objects enter the appliance nevertheless, pull the mains plug out of the socket immediately and contact a specialist.

+ The appliance has been constructed according to protection class Il (only for double insulated units without earth terminal).

e Only pull the mains plug out of the socket by the intended gripping surface. Do not pull it by the cable.

< Never plug the mains plug in or out with damp or wet hands.

+ Always pull the mains plug out of the mains socket:

“Before cleaning the appliance “_Ifthere is a thunderstorm

“If you will not be using the appliance for a long period of time ( > 1 week)

e Electrical appliances must be kept out of the reach of children. Be particularly careful if children are present. Children are not aware of the hazards involved in handing electrical appliances improperly. Children could attempt to poke objects into the appliance. There is a life-threatening danger of electrocution.

+ Do not leave the appliance unattended while operating it.

< Never place the appliance on an unstable or movable surface. Persons could be injured or the appliance damaged by it falling down.

e Live components can be exposed by opening covers or removing components (unless this can be done without tools). Contact points can also be live. If the appliance has to be opened in order to calibrate, service, repair or replace components or assemblies, all of its poles must be disconnected from all sources of voltage first. Ifthe appliance has to be kept open and under voltage during maintenance or repairs, this work may only be carried out by a specialist who is familiar with the risks involved and the relevant regulations.

+ Never connect the appliance directly after transferring it from a cold to a warm room. The condensation water that forms could destroy the appliance or result in an electric shock. Allow the device to reach room temperature before connecting it. Wait until the condensation water has evaporated. This can take some hours.

+ Do not place any naked flames such as those of burning candles on or next to the appliance.

e Do not place the appliance on soft surfaces such as carpets or beds. Do not cover the air vents of the appliance. Do not obstruct the air circulation with objects such as magazines, table cloths or curtains. This prevents the dissipation of heat from the appliance and can result in overheating.

e Only use the appliance in a moderate climate, not in tropical environments.

+ Defective mains cables may only be replaced by specialists. Danger of shock hazard!

e_lf you are not sure about the correct connection or if questions arise which are not answered by the operating

instructions, please do not hesitate to contact support or a specialist of your choice. Consult a specialist if you are in doubt the operating principle or the safety of the product.

1. Multiple system use: Several UHF systems can be used in the same performance space. Each system must be set to a different frequency (frequency marked on the back of the receiver).

2. Simultaneous output use: Unbalanced 6.35mm jack plug and balanced XLR output connectors may be used simultaneously to different external devices.

3. Range: UHF series transmitters will work at a distance of up to 30m from the receiver.

4. Noise squelch: Squelch circuit analyzes signal strength and quality to avoid interference due to environmental RF noise.

5. Low battery warning light: A red light on the microphone(s) warns the user that there is less than one hour of battery life left.

TRANSMITTER BATTERY INSTALLATION Push the battery cover open. Insert 2x AA batteries into the battery compartment with the correct polarity. Close the battery cover.

1. Receiver power connection: Connect the DC connector of the supplied AC/DC adaptor to the DC input socket on the receiver. Plug the AC connector into an appropriate mains outlet.

2. Antenna: Keep the position of the antenna at an angle of 90°.

3. Audio connection: Connect the corresponding output of the receiver via a 6.35mm Jack lead or an XLR lead to the input of a power amplifier, mixer, etc.

TIPS TO ACHIEVE MAXIMUM PERFORMANCE Make sure you can always see the receiver antenna from the transmitter position. Keep the distance from transmitter to receiver antenna as short as possible.

Avoid placing the receiver antennae near metal surfaces and obstruction.

Monitor battery power and replace the battery as soon as the red light goes on.

If stacking or rack mounting receivers in a multiple system, do not allow antennae to touch or cross. Perform a walk-through before performance or presentation. If dead spots are found, adjust location of the receiver. If dead spots remain, mark them and avoid them during performance.

For a good operation, don’t place the receiver near to KEY sources of interference. Place the receiver in 1m Ground

distance from the ground and let at least 1m free space

around the receiver.
