Lectrosonics Wireless Switch Settings/Frequency Charts

Frequency Adjustment Switches
To gain access to these switches, slide the access door open with a fingernail. These two rotary switches change the frequency of the unit. The frequency range (block) of the unit is laser engraved on this switch cover or the housing.

Adjusting the Frequency
If you are experiencing interference from another signal on your frequency, you may want to change the operating frequency of your system. The left switch changes the operating frequency in large steps and the right switch changes it in fine steps. If you are experiencing interference, change the operating frequency in fine steps to find a clear channel. If it is not possible to find a clear channel using the fine switch, return it to its original position and change the left switch by one click then try the right switch again. Important - make certain that the switches on the transmitter and receiver are set to the same position. If not, the system will not be on matched frequencies and will not work. Transmitter and receiver must also be on the same block.
