An attempt to enter frequencies outside the permissible range will yield an error
message indicating an INVALID FREQ.
Other FAULT MESSAGES are:
LNBO Little or no current is flowing to the LNB (LNB Open)
LNBS Abnormally low resistance on the LNB line (LNB Short)
FAULT- (followed by any combination of the digits 1,2,3,4,or5)
1,2,3 indicate loss of Tuner, Audio 1, Audio 2 synthesis lock.
4,5 indicate squelch of audio 1 and 2 respectively.
The KEYPAD is used to tune the system. A summary of its use is screened on the back
panel of the receiver. Entry procedure is as follows:
1: The keypad is enabled by punching #Y.
2: Punch 1 to enter transponder frequency or
Punch 2 to enter Audio 1 frequency or
Punch 3 to enter Audio 2 frequency.
3: Enter the appropriate frequency (see DISPLAY, above); four digits for audio or
five digits for a transponder. Ku transponder frequencies are five digits and are
entered directly. C band transponder frequencies are entered as four digits, such
as "3760" followed by a # (3760#).
Caution: If a wrong number is punched in step 2, it can be cancelled by depressing
the Y key. However, once you have started entering any frequency, that
entry must be completed before anything else can be done. Thus, if you have
inadvertently started entering undesired input in the place of previously correct
information, you must complete your entry and then re-enter the original number.
The PANIC BUTTON duplicates the power-on-reset function to the microcomputer. It is
used much the same as a computer reset button. It can not be used to overcome
an incorrect entry as mentioned in the previous paragraph, because the micro writes
frequency entries into non-volatile memory.
