  If the devices are to be put out of oper-ation definitively, dispose of the devices in accordance with local regulations.

Before Operation

Connecting the receiver

1. Connect the receiver to the following device (e. g. amplifier, mixer). For this purpose, two audio outputs are provided:
   • MIC OUT (10) as an XLR jack, balanced to connect a microphone input
   •  LINE OUT (11) as a 6.3 mm jack, unbal. to connect an input with line level; use the connection cable provided
2. Connect the power supply unit provided to the power supply jack (8) and to a mains socket (230 V / 50 Hz).

Inserting batteries into the microphone
Two 1.5 V batteries of size AA are required for operation of the wireless microphone.

• Always insert batteries of the same type and always replace all of them.
• If the microphone is not in use for a longer period of time, always remove the batteries to prevent damage due to battery leakage.
  To open the battery compartment (17), press the arrow of the battery compartment cover and push the cover downwards. Insert the batteries with the positive and negative poles as indicated in the compartment, then replace the cover.
  Never put batteries in the household waste. Always dispose of the batteries in accordance with local regulations.

Setting the transmission power
On the wireless microphone, adjust the trans-mission power with the switch POWER (19) in the battery compartment:

• upper position HI = high power for a long transmission range, but reduced battery life
• lower position LO = low power for a long battery life, but reduced transmission range

Adjusting the transmission channel
To adjust a free transmission channel on the re-ceiver, either use the automatic scan function or adjust the channel manually. Then simply press a button to adjust the wireless microphone to the same channel via IR signal.

1. Switch on the receiver with the POWER switch (9). To switch on the microphone, set the switch (16) to the upper position. After switching on, the corresponding display (3, 14) lights up.

2. To automatically scan a free channel, press the button SELECT (2) briefly. To indicate the scan, one segment of the numerical display element starts moving around on the dis-play (3):
   After a short while, the display shows the number of the channel found. The corre-sponding frequency can be found in the table on page 3.

3. To manually adjust a specific transmission frequency, find the corresponding channel number in the table on page 3. To adjust the channel number, keep the button SELECT (2) pressed until the units digit on the display (3) starts flashing. Press the button briefly to ad-just the units digit. Keep the button pressed again until the tens digit on the display starts flashing. Press the button briefly to adjust the tens digit. A few seconds after you have pressed the button for the last time, the tens digit will stop flashing to indicate that the channel adjustment has been stored.

4. Point the IR sensor (15) of the microphone towards the IR window (6) on the receiver. The distance must not exceed 1.5 m. Make sure that there are no obstacles between the sensor and the IR window.
   Keep the button ACT (7) pressed for a few seconds until the display backlight of the microphone has been activated. Thus, the microphone and the receiver have been set to the same channel. The display (14) shows the channel number.

Operation

1. Put the receiving antennas (1) in a vertical position.

2. Switch on the receiver with the POWER switch (9) first. The LED AF (4) flashes twice. The display (3) shows the transmission chan-nel adjusted.
   If one of the reception LEDs RF (5) lights up while the wireless microphone is still switched off, interfering signals or signals from another wireless system are received. In this case, adjust a different channel (☞ chap-ter 4.4).

3. To switch on the microphone, set the switch (16) to the upper position. In the mid- position, the microphone is also switched on, but the microphone signal is muted.After switching on, the backlight of the display (14) lights up for a few seconds. The display shows the channel adjusted and the battery status:
   Note: Replace the batteries when the indication BATT starts flashing.

4. ) When the microphone is switched on, one of the reception LEDs RF A or B (5) lights up on the receiver to indicate which receiving part supplies the best signal. If none of them lights up, please check:

   • Have the microphone and the receiver been set to the same channel?
     If different channels are indicated on the receiver and on the microphone, proceed with step 4 of chapter 4.4.

   • Are the batteries of the microphone discharged?

   • Has the microphone been set to a low transmission power? (☞ chapter 4.3)

   • Is the distance between the microphone and the receiver too long?

   • Is the reception disturbed by metal objects in the transmission path?

   • Is it possible to improve the reception when you turn the receiving antennas (1)?g Has the interference suppression been set step 6)

5. Switch on the following audio device or advance the corresponding mixer control. Speak / sing into the microphone and match the output level of the receiver to the input of the following device with the control VOL-UME (12).

6. Use the control SQUELCH (13) to adjust the threshold value at which the interference suppression is to be activated. The interfer-ence suppression will mute the receiver in speech / music pauses when interfering signals are received and their levels are below the threshold value adjusted. A high threshold value, however, will also reduce the trans-mission range of the microphone system: If the power of the radio signal falls below the threshold value adjusted, the receiver will also be muted. Therefore, adjust a high threshold value (turn the control towards MAX) when the reception is good and a low value (turn the control towards MIN) when the distance between the microphone and the receiver is long.

7. The microphone has a lock feature. To ac-tivate the lock, set the switch LOCK (18) in the battery compartment to the position ON. The displays shows a key symbol and it will not be possible to switch off the microphone with the switch (16) or to set it to a different channel via IR signal. However, it will still be possible to mute the microphone when you set the switch (16) to the mid-position or the lower position.

8. After operation, switch off the devices with the corresponding switch (9, 16). The power supply unit of the receiver has a low power consumption even when the receiver is switched off. Therefore, disconnect the power supply unit from the mains socket when the microphone system is not used for a longer period of time.
