7.3. Repeater Settings
7.3.1. Indicator Light Instructions
• The equipment works correctly when power LED indicator light P is on, any other status means
power failure or equipment failure.
• The equipment works correctly when both Up-link indicator light U and down-link indicator light
D are on. The up-link incoming signal is very strong and the equipment output is large when the
light U is flashing slowly. The down-link incoming signal is very strong and the output of the
equipment is large when the light D is flashing slowly.
• Either indicator light U or D is off in case the up-link or down-link breaks down. The equipment
experiences self-excitation when both U and D lights are flashing quickly.
Troubleshooting
• When the ALM light is flicking or on, and the booster has self-oscillation issue, it indicates the
wrong installation of indoor and outdoor antenna. In this case, please, read antenna installation
instructions again and re-install the antennas.
• When the ALM light is flicking or on, and the input signal is too strong, please, change the
direction or place of your outdoor antenna.
7.4. System Test
7.4.1. Check whether the coverage is good
1. Take a test with a mobile phone or a data card (engineering mobile phone is preferred).
To test signal level with a cell phone, make use of its engineering mode (Field Test
Mode), which is an application available in free access or a phone mode requiring no
extra setups. On most used mobile OS (operating systems) 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.
Note! To get parameters for 2G, 3G and LTE, disable WiFi. In case you cannot find Field
Test Mode on your cell phone, use bars on the screen of your mobile phone to evaluate
the change.
