2.2 Technical Specifications

The following are the key operating specifications for the SD Master Station 900MHz and
400MHz variants. Items are separated into Transmit (TX) and Receive (RX) categories. Ongoing
product improvements may result in specification changes, and GE MDS reserves the right to
make such changes without obligation to any party. Should you require an exact specification for
the build of your unit, please contact the factory for additional assistance.
