Installation Planning

FILTER LIMITS: The DVR-LX is shipped equipped with custom filters tuned to the
specified frequency range provided by the customer. Programming the DVR-LX /
MSU to operate on frequencies outside of the original specified bands may result in
intermittent or complete loss of communications. Frequency changes may require
filter retuning or replacement.
TRANSMIT POWER (CROSS-BAND): The cross-band DVR-LX can be interfaced to
a high power MSU, however, the transmit power of the MSU must be reduced to
comply with the maximum power restrictions described in the DVRS RF Safety
3
Booklet .
TRANSMIT POWER (IN-BAND): In all in-band DVRS configurations, the MSU
transmit power must not exceed 50 Watts on DVRS Enabled MSU Modes due to the
in-band filters' power rating. The in-band filters connected to the MSU have typical
insertion loss of 1.5dB.
