Since the HT 40 PRO handheld transmitter has been designed specifically for the integrated microphone element, there is no need to set gain on the handheld transmitter. Therefore, the handheld transmitter has no level or gain control. Switch power to your sound system or amplifier on. Talk or sing into the microphone and set the levels on your mixer or amplifier referring to the appropriate instruction manual, or by ear. If you tune the transmitter and receiver to different frequencies, no signal will be transmitted!Switch power to your sound system or amplifier on.

Move the transmitter around the area where you will use the system to check the area for "dead spots", i. , places where the field strength seems to drop and reception deteriorates. If you find any dead spots, try to eliminate them by repositioning the receiver. If this does not help, avoid the dead spots. The RF OK LED on the receiver going out means no signal is being received or the squelch* is active. Switch the transmitter on, move closer to the receiver, or set the squelch threshold* to the point that the green RF OK LED will be lit.
