Tuning
The tuner check
indicates
whether
the receiver's
tuner is tuning
to a satellite
transponder.
If the signal strength is good but the tuning test fails, suspect a defective
receiver or LNB.
Phone
During
the phone
portion of the self test, the receiver
checks for a dial tone and
performs
an internal loopback test. If the phone test detect a problem, it will put the
message
"Check
phone connections"
on the screen.
If the phone check detects no
problems,
the message OK will appear on the screen.
If the phone
check
fails, you must confirm
the operation
of the telephone
line
connected to the receiver.
Do this by unplugging the receiver and connecting
a known
good telephone
in the receiver's
place.
If the telephone
works, suspect a defective
receiver.
If the telephone doesn't work, suspect a defective connection
or a bad cable
b_tween the junction
box and the receiver's
connecting
point.
Access Card
During this test, the receiver sends a code to the access card and looks or a reply. If
the card replies correctly, the card is OK. If the card doesn't answer back or answers
incorrectly, the card is malfunctioning.
