Specifications of the CWD7787
1. The location and orientation of the Antenna are important factors in the RF performance. the antenna is adjusted to achieve
the best range. The range is dependent on its placement and the building in which it is used. The construction of the
building, obstructions, and RF interference from other devices are factors determining the effective range of the unit. To
prevent unit-to-unit RF interference, multiple transceivers operating at the same frequencies should not be installed within
3-5 feet of each other.
Physical Description
The transceiver, shown below, consists of various components attached to a printed circuit board.
