PREAMBLE

In cellular systems, repeaters are used to extend the coverage of a base station in
regions where, due to topological or structural conditions, weak field strengths
disable communication. MIKOM is a leading manufacturer of repeaters, providing
excellent electrical characteristics. The repeaters are light-weight and easy to install.
MIKOM repeaters provide a preferred solution for extended cellular coverage.

This repeater has been built using only highly reliable materials. A comprehensive
quality assurance has been carried out on all fabrication steps, ensuring constant
quality of the product. Every repeater leaves the factory only after a thorough final
acceptance test, accompanied by a test certificate, which guarantees perfect
function.

Any intervention must be carried out by authorised persons only. If technical
assistance for the repeater MR303D Varia is needed, contact the local sales office
(see List of international sales offices on the following page) or contact MIKOM
