TROUBLESHOOTING GUIDE 10
We have carefully tested and have found no
problems in the supplied DA1917SX unit; however,
we would like to offer these suggestions:
• Please make sure that you have the correct
setting of the Sync Source Switch. If you pass
RGBS signal formats, the switch must be in
the SYNC position. If you pass RGsB or
Composite Video signal formats, the switch
must be in the GREEN position.
• Make sure that the correct power adapter is
connected to the unit.
• Please make sure that the input amplitude of
the analog signal is less than 1.5V.
• Please use the Altinex supplied external
adapter (9V, 500mA).
• Please make sure that the proper quality of
cables is used. We recommend the Altinex
made cables for the best results.
• If the problem shows up after continuous
usage at higher voltage, higher temperature,
higher humidity, or at other extreme
environmental conditions, please correct the
problem.
