Problem
Resolution
After installing the
booster system, you
have no signal or
reception where your
car is parked.
1.
Check the outside signal closest as you can to
the outside antenna. To measure your existing
cell signal:
Apple iPhoneD: dial *3001#12345#*and press
Call. In the top-left corner, a number replaces the
bars.
Android devices: download apps to measure
exact signal strength, such as Network Signal
Info in Google Play store. Search "check real
signal strength" to find other cell signal
measurement apps.
2.
Double-check cable connections to both
antennas and booster.
3.
Be sure your booster's dB gain is turned up to at
least 40dB - 45dBon each dial.
One of the red lights
next to the dials on
your booster is
flashing.
1.
Turn down the dB gain on the dial until the light
goes OFF or turns yellow.
2.
Be sure the inside panel antenna is facing away
from the outside antenna.
3.
Use the recommended 6-10 ft. of antenna
separation:
•
50dB
30-40 ft. separation
•
45dB
20-30 ft. separation
•
40dB
10-20 ft. separation
•
35dB
10 ft. separation
