Switching the radio microphone on/off

왘 Use the ON/OFF switch  to switch the radio microphone on or off.

If the radio microphone is switched on, the red LED  lights up.

Note:

Remove the battery when the transmitter will not be used for

extended periods of time.

Selecting and changing a channel

왘 Switch off the radio microphone.

왘 Open the radio microphone (see “Inserting/replacing the battery”

on page 22).

왘 Use a small screwdriver to set the channel selector switch  to the

desired channel. You can switch between four different channels

(see “Selecting a channel” on page 24).

Sensitivity of the radio microphone

You can vary the bass reproduction by increasing/decreasing the

talking distance.

Setting up the system

Before starting transmission, do a soundcheck and set up the system as

follows:

Setting up the reception

The receiver’s four LEDs (RF LEVEL)  indicate the level of the received

RF signal. With the transmitter, walk up and down the transmission

area and check if the received RF signal is sufficient everywhere.

Reception is good if all four LEDs light up. Please observe the following:

y Transmission range depends to a large extent on location and can be

up to 100 m. Observe a minimum distance of 3 m between

transmitter and receiver. There should be a “free line of sight”

between transmitting and receiving antennas.

y Do not operate the system close to metal objects such as cross

members or reinforced-concrete walls. Computers or mobile phones

in direct proximity to the antenna will interfere with the reception.

y Each transmitter requires a receiver. When using several trans-

mission links simultaneously, make sure that all transmission links

operate on different channels.
