Interference, which may be heard in a headset as popping sounds, may occur whenever other equipment such as Wi-Fi systems , DMX wireless lighting systems, etc. use the same frequency band that the DX-210 is using. Some systems can be limited to one portion of the 2.4 band. If so, the DX210 can be set to the opposite half of the 2.4 GHz to 2.48 GHz band. To avoid this type of interference, select the upper or lower part of the frequency range.







● Turn on the base station power. An “8” will appear on the STATUS display for a few seconds.
● After the “8” disappears and the STATUS display is blank (primary base station) or shows a double bar (secondary base station), press and hold the CLR/BND button and then, while you are still holding the CLR/BND button, press and hold the REG button and wait until a L, H or A appears, and then release both buttons.
NOTE: Base stations are shipped in the A (default) position.
● Press the CLR/BND button to cycle through parts of the frequency band, (L = Low end, H = High end, and A = All) and stop on the desired setting.
● Wait until “c” appears on the display.
NOTE: “c” will only appear on the STATUS display if you are setting the frequency band the first time, or you are changing the setting. If you stop at L, H or A that was already set, an “8” will appear for a few
seconds and the STATUS display will become blank.
● Re-Register all Beltpacks (COMMUNICATORs) to be used with the base station.
NOTE: If you change a base station’s frequency band setting, you will have to re-register all beltpacks (Communicator) that were registered to the base station.
