Tuning
The receiver LCD display shows the channel number (2 separate channel numbers on dual receivers) and RF and AF level meters to indicate if
Radio Frequency (RF) carrier is being received and if Audio Frequency (AF) is being heard by the receiver.
To tune the transmitter(s) to the receiver, the receiver can send an Infra Red (IR) signal to the transmitter –this is called “IR Sync.”.To activate
this, select the desired channel using the Frequency Up/Down buttons (see diagram above) and the channel number selected will show on the
LCD display. Briefly press (do not hold) the “POWER / IR SYNC” button on the receiver and the frequency value will flash on the LCD display.
For handheld units, hold the transmitter with the IR sensor (either on the end or rear of the microphone body) near to the IR sender on the UHF
receiver unit (see diagram above). The display on the handheld unit will flash until both transmitter and receiver frequencies are matched and
channel numbers stop flashing.
For beltpack units, open the battery compartment to reveal the IR sensor inside and hold this near to the IR sender on the UHF receiver. The
display on the beltpack unit will flash until both transmitter and receiver frequencies are matched and channel numbers stop flashing.
In use
Gradually increase the microphone level(s) on the receiver and then increase the volume on the mixer or amplifier until the sound from the
microphone can be heard through the equipment.
During use, it may be useful for the reception of the microphone to be muted for a short period of time (e.g. to avoid feedback when walking
across the front of a speaker or avoid handling noise when placing the microphone down momentarily or adjusting a neckband microphone). In
these circumstances, it may be better to move the transmitter switch to the “MUTE” position, which maintains the radio frequency carrier signal
but mutes the microphone input. When this switch is moved back to the “ON” position, the sound will be immediately restored.
If the wireless system is not to be used for more than a few seconds, it is preferable to slide the transmitter switch to the “OFF” position, which
mutes and deactivates the radio signal and powers down the transmitter. For beltpacks, hold the “ON / CHECK” button until the word “OFF” is
displayed and release to power down. Be sure to turn down the volume of the mixer or amplifier and then switch off the receiver.
Unplug signal leads from the receiver and mixer or amplifier when moving or packing away. If the system is not to be used for long periods of
time, remove the batteries from the transmitter and unplug the power adapter from the receiver and the mains outlet. Retracting and/or removing
the antennae can also help avoid damage when the system is not in use.
