SUGGESTIONS AND RECOMMENDATIONS

TO PREVENT INTERFERENCES:

Keep the transmitters at least 5-6 metres from every active receiver.

The receiver antennas should not be too close to each other.

Make sure the transmitter batteries are fully charged and efficient.

Optimise the receiver squelch level.

PROBLEMSWITHTHE SIMULTANEOUS USE OF MULTIPLE MICROPHONES:

Absolutely avoid the use of two (or more) transmitters tuned to the same frequency.

ADVICE TO FIND OUT THE INTERFERENCE ORIGIN:

Make sure the radiomicrophone is actually the cause by switching off the receiver and disconnecting the connection cables momentarily (to see if the problem persists).

Switch off all transmitters and check if all receivers go to “mute” status: this allows you to verify the possible presence of external interfering sources.

Switch on one transmitter at a time, walking around in the room (or outdoor) to find the worst condition and identify the receiver coming out from the “mute” status. If one receiver not tuned to the frequency of the used transmitter comes out from “mute” status, there is a problem of intermodulation and it is therefore necessary to change the frequency / model.

PREVENT FEEDBACKS:

The acoustic feedback (usually a sharp whistling sound) occurs when a microphone is used too close to loudspeakers; therefore it is necessary to keep the distance.

Turn down the radiomicrophone volume (receiver“AUDIO OUT”control).

Do NOT aim the microphone capsule to loudspeakers.

PREVENT DROPOUTS:

Reflections caused by walls in reinforced concrete or metallic structures may cause “dropouts” (zones where it is not possible to get a perfect radio transmission). It is therefore advisable to check beforehand the reception quality where the mic.will be used.In case of dropouts,change the location of the receiver and/or move the antennas (modifying their inclination).

MAINTENANCE

Clean the plastic surfaces using a soft cloth dampened with non-alcoholic detergent.
