LCD-300GD FAQ
For maximum precision in signal level testing, switch your cell phone into Field Test Mode and see dB parameter. The closer dB signal level to 0, the better cell phone reception you’ll get.
- -105 to -100 = Bad/drop call
- -99 to -90 = Getting bad/signal may break up
- -89 to -80 = OK/shouldn't have problems, but maybe
- -79 to -65 = Good
- Over -65 = Excellent
Your task is to get at least -79dB signal to ensure reliable communication and strong signal inside the building.
The maximum length differs for each cell phone repeater. For powerful repeaters like NS5000 or NS2500 the maximum length can be 25-30 meters; whilst for smaller models like MA300 o NS250 it is 15-20 meters. However, we strongly recommend our customers using the standard cable length (included into the package) for their particular unit for better signal quality.
Every 4G cell phone repeater has LED indicators. The green LED indicates the device status. When it is on, the cell phone repeater is powered on and is working properly. The red LED indicates the 4G signal reception. When it glows or blinks, the device is receiving a 4G/LTE signal. Beware of Alarm LED indicating problems in repeater functioning. When Alarm is ON (red), the repeater will not work correctly.
Please, also note that the quantity of LEDs and their indications may differ depending on a repeater model. For more information read a manual to your cell phone repeater model.
If you don't know exactly where your operator's base station is located, go through the antenna aiming process for getting the best result. To aim the antenna correctly, follow the steps below:
- Setup the entire booster system, including antennas and cables, and power it on.
- A person on the roof aims the antenna in a certain direction. The other person inside waits for 1 minute and checks signal level on the phone.
- Then rotate the antenna its 1/8th of the way around, which equals 45 degrees. The person inside does the same procedure with signal testing.
- Repeat the process 8 times until you try all 8 directions, in every 45 degrees sector.
- Compare the results of signal testing – the closer dB parameter to 0, the better booster performance you get.
- Fix the antenna in the direction with better signal result.
Note! We recommend mounting the antenna on the side of the building aiming away from the building, which will reduce amount of possible obstacles. For your convenience and acceleration of the process perform the testing in pair.
To find out the precise signal level, switch your cell phone into Field test mode (FTM). It’s a phone mode requiring no extra setups and available on most popular mobile OS (operating systems). Depending on your OS, the test mode can be started as follows:
- iOS. Type * 3001 # 12345 # * and hit Call
- Android. Type * # * # 197328640 # * # * to activate
- Windows. Type # # 3282 # and start.
- Blackberry. Press TOOLS, SETTINGS, STATUS or OPTIONS, STATUS.
