status LED remains dark. You can check all transmitter parameters and set the carrier
frequency (refer to section 3.6) and input gain (refer to section 3.8).
• We recommend setting the carrier frequency in SILENT mode only. This is the
only way to make sure you won't "go on air" on a frequency that is not allocated
or coordinated and risk "jamming" some other radio service or active radio mic.
Depending on the way you switch power to the transmitter ON, the transmitter will be in ei-
ther LOCK mode or SILENT mode on powering up.
• If you are not sure what carrier frequency the transmitter is tuned to, switch the
transmitter to SILENT mode (refer to section 3.4.1 below) and check that the cur-
rent carrier frequency is legal and identical to the frequency selected on the re-
ceiver.
1. Push and hold the setup switch (6) until the backlighting of the display (2) comes on.
The display (2) will first show the firmware version and then the currently selected car-
rier frequency in MHz.
As the backlighting goes out, the display changes as follows:
The transmitter is now in SILENT mode.
2. If the carrier frequency is not an allocated or coordinated one and/or different from the
receiver frequency, set the transmitter to a suitable, legal frequency referring to section
3.6.
1. Press the ON/OFF button (3) for approx. 0.6 seconds.
2. As soon as the below screen appears on the display (2), the transmitter is in LOCK mode.
The "LOCK" label indicates that all controls except for the MUTE switch are electroni-
cally locked to prevent misadjustment.
• If the microphone is muted, the "MUTE" label appears on the display and the status LED
is lit red. If the microphone is active, "MUTE" will not appear and the status LED will be
lit green.
