(1) Attach the antenna to the preamplifier and turn
on the power of the main unit and the preamplifier.
(2) Since the preamplifier receives weak radio waves
from artificial satellites, take it outdoors. Please do it
in a place where you can see the sky and there is
nothing blocking your view such as buildings. Wait
for the LED for GPS among the 4 LEDs to switch from
blinking to lit out. It may take 5 to 10 minutes to
synchronize the GPS signal from the satellite with
the preamplifier.
