FOR EQUIPMENT THAT CONNECTS TO THE POWER MAINS
24. CAUTION: If the power cord of the device is equipped with an earthing contact,then it must be connected to an outlet with a protective
ground. Never deactivate the protective ground of a power cord.
25. If the equipment has been exposed to strong fluctuations in temperature (for example, after transport), do not switch it on immediately.
Moisture and condensation could damage the equipment. Do not switch on the equipment until it has reached room temperature.
26. Before connecting the equipment to the power outlet, first verify that the mains voltage and frequency match the values specified on the
equipment. If the equipment has a voltage selectionswitch, connectthe equipment to the power outlet onlyif the equipment values and the
mainspower values match. If the included power cord or power adapter does notfit in your wall outlet, contact your electrician.
27. Do not step on the power cord. Make certain that the power cable does not become kinked, especiallyat the mains outlet and/or power
adapter and the equipment connector.
28. When connecting the equipment, make certain that the power cord or power adapter is always freely accessible. Always disconnect the
equipment from the power supply if the equipment is not in use orif you want to clean the equipment.Always unplug the power cord and
power adapter fromthe power outlet at the plug oradapter and notby pullingon the cord.Never touch the power cord and power adapter
with wet hands.
29. Whenever possible, avoid switching the equipment on and off in quick succession because otherwise this can shorten the useful life of
the equipment.
30. IMPORTANT INFORMATION:Replace fuses only with fuses of the same type and rating. If a fuse blows repeatedly, please contact an
authorised service centre.
31. Todisconnect the equipment from the power mains completely,unplug the power cord or power adapter from the power outlet.
32. If your device is equipped with a Volex power connector,the mating Volex equipment connector must be unlocked before it can be removed.
However,this alsomeansthattheequipment can slideandfall down ifthepowercableispulled,whichcanleadto personalinjuriesand/or
other damage. For this reason, always be careful when laying cables.
33. Unplug the powercord and power adapter from the power outlet ifthere isa risk of a lightning strike or before extended periods of disuse.

Hearing damage due to high volume and prolonged exposure: When in use, this product is capable of producing high sound-pressure levels
(SPL) that can leadto irreversible hearing damage inperformers,employees, and audience members. Forthis reason, avoidprolonged
exposure to volumes in excess of 90 dB.
NOTE:This equipment has been tested and found to comply with the limits fora Class B digital device,pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment
generates, uses andcan radiate radio frequency energy and, ifnot installed andused in accordance with the instructions,may cause
harmful interference toradio communications. However,there is noguarantee thatinterferencewillnotoccur in aparticular installation.If
this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

INTRODUCTION
Developed inGermany,the UHF Diversitywireless systems fromthe U300® seriesa deliver excellent audioperformance. They achievea range
of 100 metres in ideal conditions and are available in three frequency bands: 470-542MHz. Up tosix U300®systems can be used
simultaneously for each frequency band.Convenient one-touch synchronisation of transmitter and receiver
via infra-red facilitates fast,
trouble-free wireless connection and the squelch function with pilot tone ensures fail-safe operation.
• Available with hand or pockettransmitter
• Infra-red frequency synchronisation
• Fail-safe operation provided by pilot tone
• 12 channels
• Up to 6 systems can be used simultaneously
• Belt-pack transmitter with gain control and status LED
• Dynamic hand-held microphone with status LED
• U500® microphone heads also suitable for U300® hand-held transmitter
• Long battery life

• Available in the following frequencies: 470-542MHz (LDU 504.7/LDU 505.1/LDU 305.1/LDU 304.7)
Please note: The use of the wireless microphone system may require a license, depending on the country of use. For detailed information
please contact the relevant authority in your country.
Pilot tone
The pilot tone function protects a wireless microphone system against interference, for example, unwanted signals from other radio trans-
mission systems. The transmitter adds a second, inaudible signal (the pilot tone) to the actual signal which is to be transmitted. The receiver
identifies it as the matching pilot tone and frees the associated signal. Signals without a matching pilot tone remain muted.
