Note:
It is not allowed to operate the Repeater without termination of the
antenna connections! The termination can be performed by the antenna
connection as well as a dummy load or the 50-Ohm-terminated connection
of a measuring instrument.

Before bringing the Repeater system into service it is necessary to measure the antenna
isolation. The Repeater system has its maximum available gain when the attenuation is set to
zero. On site the maximum allowed gain is 15 dB less than the value of the antenna isolation.
In order to check the function of the Repeater system on site it is advisable to operate the
Repeater system with 50 Ohm termination. This makes it possible to set the necessary gain
and to test the set value without the necessity of transmitting on air.

In order to perform settings the Repeater has to be opened. Please, ensure not to damage the
seals, which are on the modules situated on the RF modules inside of the Repeater, because
this would lead to risk the success of warranty claims.
