Step 7:
Compare Results
Using the field test mode described in step 3, measure the new signal
strength and write it down here ___________.
Compare this number with the original reading you took in the same part of the house.
If the number is higher (closer to zero) than the original reading without booster, your
booster is working. If it is not, look at the lights on the booster and the section at the
end of this manual “Test System: Lights”.
Users on iOS 11 and above will need to use an alternative method using the bar
indicator on your cell phone and/or placing calls in different locations.
Did you know a signal increase in just
3dB is 2 times the power and signal amplification!
