20V DC! Violation o this operating condition can lead to losing warranty and
destroying the device!
6. Setting of antenna gain in the range -9 to +18 dB
Antenna gain can be set in the range o -9 to +18 dB.
enter settings long (2 seconds) press o UP or DOWN buttons
change settings short press o UP or DOWN button
save settings i no button is pressed during 3 seconds, gain value stops to
lash and actual value is stored in memory

settings.
7. Setting of right gain value to get the best performance
To get the best RF per ormance o your wireless system, setting of right value of
antenna gain is important. Allways start with setting the gain, which covers losses o
your coaxial cable. Losses o common types o coaxial cables are in the table on page 8.
I signal indicator on your receiver indicates very weak signal even i you set the
gain which covers coaxial cable losses, you can try to add more gain and get
better per ormance. For example in places with low RF noise this gain can add
multiple working distance o your wireless system.
