FOR EQUIPMENT THAT CONNECTS TO THE POWER MAINS 24. CAUTION:If the power cord of the device is equipped with an earthing contact,then itmust beconnected 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 equipmentto the poweroutlet,first verifythat the mains voltage and frequency match the values specified on the equipment.If the equipment has a voltage selection switch, connectthe equipment to the power outlet only if the equipment values and the mains power values match. If the included power cord or power adapter does not fit inyour wall outlet, contact your electrician. 27. Do not step on the power cord.Make certain that the power cable does not become kinked,especially atthe mains outlet and/or power adapter and the equipment connector. 28.

NOTE:This equipment has been tested and found to comply with the limits for a 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 and can radiate radio frequency energy and,if not installed and used in accordance with the instructions, may cause harmfulinterferencetoradiocommunications.However,thereisnoguaranteethatinterferencewillnotoccur inaparticularinstallation.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.
- Consult the dealer or an experienced radio/TV technician for help. INTRODUCTION DevelopedinGermany,theUHFDiversitywirelesssystemsfromtheU300seriesadeliverexcellent audioperformance.Theyachievea range of 100 metres in ideal conditions and are available in three frequency bands: 470-542MHz. Up to six U300 systems can be used simultaneously for each frequencyband.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 4 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. 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.

Move the switch to the ON position to turn on the hand-held transmitter, and to the OFF position to turn it off. 17 STATUS LED If the charge status of the batteries is sufficient, the LED lights up green when the hand transmitter is switched on. If the LED lights up red, the charge status is weak. In this case, replace the batteries (2 x AA/LR6 type, alkaline). During the synchronisation process, the LED flashes green and amber. 18 IR INTERFACE Infra-red interface for synchronising the radio channel from receiver and transmitter. 19 BATTERY COMPARTMENT COVER Toreplace the batteries, open the hand transmitter battery compartment by rotating it anti-clockwise and pulling it from the housing.Remove the used batteries and replace with new batteries (AA),following the diagram in the battery compartment.

(Examples: Headset = MIC, guitar with passive pickups = 0dB, guitar with active pickups
= -10dB). 8 27 BATTERY COMPARTMENT Toreplace the batteries, open the battery compartment of the pocket transmitter by simultaneously pressing both markers on the sides of the battery cover and opening it forwards. Remove theused batteries and replace with new batteries (AA/LR6,alkaline), following the diagram in the battery compartment. Replace the battery compartment cover on the housing and click it into place. If the transmitter is not used for a long period, remove the batteries to avoid damage to the transmitter from leaking batteries.

Check if the transmitter is turned on. Check the batteries in the transmitter. Receiver: Display lighting is switched off Receiver: No reception displayed on either antenna A or B. Transmitter: Device is switched on. Charge status of the batteries is ok. Checkthepowersupplyforthereceiverandwhether the receiver is switchedon. Checkwhetherradiofrequencyofthetransmitterand the receiver are matching. Reduce the distance between transmitter and receiver. Ensure that there is a direct line of sight between the transmitter and the receiver. Ensurethattheantennasonthereceiverareposi-
tioned in an upward V-shape. Increasethesignallevelorincreasetheinputsensi-
tivity on the pocket transmitter. Remove possible sources of interference (digital devices, other radio systems). Receiver:Reception on antenna A or B is displayed. Distortion and interference Receiver: Radio signal is displayed Distorted sound Transmitter: Status LED is lit up red. Replace the batteries in the transmitter.
