damage to the connectors. Use a short piece of
coax with a connector on one end, or Winegard’s
TE-1400 voltage tester (available from your
Winegard Distributor).

been selected
for 10 minutes or
more? See
Note. For the
initial search,
time could equal
10 minutes.

use of the AS-2003,
GPS acquisition may
take longer. Also,
obstructions (buildings,
trees, hills, etc.) will
delay acquisition time.

V. On, Search and Off LEDs are on (Will not find signal)
Clear view of
SW sky
Any satellite within 20° longitude of the desired
satellite will be included as a required satellite
in the Search routine. To find 119, for example,
101, 110 and 119 are all required for a success-
ful Search routine.
Satellites 101, 110 and 119 are within 20° of each other Is the satellite
dish level,
within 3° with
horizon?
YES
NO
Try to level dish to
within 1° of horizon.
The unit will find the
signal with a 1° to
3° tilt, but search
time increases.

Switch within 6 minutes
after unit has acquired
satellite signal on
satellite 119?
YES YES NO

retest the
Check
Switch
function?
NO
Wait for unit to acquire
satellite signal on 119.
Run Check Switch again
within 6 minutes.
NO
Retest Check
Switch function.
Does the
dish move
while per-
forming the
Check
Switch?
Does the dish rotate almost a full
revolution while trying to locate
the second satellite during the
Check Switch function? Fig. 20.
NO
Connect LNBF correctly.
NO

mary coax connected
from the Satellite In jack
on the receiver back to
the coax connection of
the left side of the elec-
tronics box? Fig. 14, 15.
YES
NO
YES
Is the LNBF coax con-
nected from LNBF to
coax connection on the
right of electronics
box? Fig. 16, 17.

search and run-
ning the Check
Switch again? For
DIRECTV, is the
receiver set to

Check Switch
function; for
DIRECTV, set
receiver correctly.
