Trouble shooting
The LED POWER 쐋 does not light up
The unit is not powered.
Disturbed reception or no reception
Possible causes:
y Transmitting antennas are not within the reception area
y Transmitters or receivers are not turned on
y Transmitter batteries are not inserted or batteries are
low
y The antennas are not connected correctly
y The connecting cables are defective
y Too high cable attenuation due to too long antenna
cables or wrong type of antenna cable
y The selected transmission and receiving frequencies are
not within the frequency window of the selective input
modules (optional) and antenna boosters (optional)
y When using active antennas or antenna boosters, the
supply voltage must be turned on (see “Connecting the
antennas” on page 6). The two LEDs DC FEED ANT A 쐃
and DC FEED ANT B 쐇 light up green.
If the LEDs do not light up even though the two switches
DC-Feed ANT A and DC-Feed ANT B 쐈 are set to position
“ON”, the antenna inputs are short-circuited.
