WI-FI systems, wireless DMX systems, other HME Base Stations, etc. use the same frequency band. If these systems can be limited to one portion of the band, then the DX121 can be set to the opposite half of the 2.4 GHz to 2.48 GHz band. - Page 15 Base Station Initialization For multiple HME Base Stations to operate without interference, they must be properly initialized before ® performing any other setups. After initializing each Base Station, register each COMMUNICATOR that will be used with that base according to the procedures on pages 13 – 20. NOTE: Base stations must be set up for split-band operation prior to initialization.
- Page 16 • Repeat these steps for each remaining secondary base. Use a different number for each. Only the primary base and the secondary base you are working with should have power on during initialization. All other equipment should be off. ® •...

2400MHz cordless telephone interference — If there is a 2400MHz cordless telephone nearby, interference may occur. However, because the DX121 is a frequency-hopping system, this problem is unlikely. If it does occur, changing frequencies on the telephone may alleviate the problem. If not, move the phone as far as practical from the Base Station, or use another type phone. -
