STATEMENT INFORMATION TO THE USER
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user will be required to correct the interference
at his own expense.
These limits are designed to provide reasonable protection against harmful interference in a
residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in a particular Installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encourage to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet of a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for assistance.
Changes or modification not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
Connecting of peripherals requires the use of grounded shielded signal cables.

2.2.2 Downlink/ Uplink Path
The user may select frequency bands according to the site conditions. After receiving a signal
from the donor antenna(s), the repeater improves it and sends a securely isolated signal out to
the service antenna(s). Each amplifier module has its own separate digital filter module (DFM).
The amplifier module consists of a down converter, up converters, cavity filter, and power
amplifier (PAU).
In the Downlink Path:
1.
RF Signal is received from the donor antenna through the input port.
2. The signal is then converted from RF to IF,
3. The IF signal is digitized by the DA converter,
4. The digital signal is filtered by the DFM (FPGA),
5. The modulator converts the digital signal to an analog RF signal and transmits to
the amplifier.
6. Amplifier outputs final signal to service antennas at desired output power.
Uplink path works in reverse order.

stable Downlink RSSI input level in the range of -85dBm to -60dBm.
1. Connect your laptop to the LAN port on the repeater with a Crossover Ethernet cable.
2. Verify your laptop has all wireless connections turned off and is set to obtain an IP
address automatically, or you may use a fixed IP address: 172.16.6.82, with a Subnet
Mask of 255.255.255.252, no default Gateway.
3. Open web browser and enter: 172.16.6.81.
4. User name: admin.
5. Password: admin.
3.2.2 Quick Setup
1. Go to the RF Configuration page.
2. Before the Amplifier (HPA) can be turned on, set the Uplink and Downlink attenuation
(ATT) to the maximum value and click Apply.
3. Select the correct Band Block and set the ALC Downlink and Uplink Limits to the desired
level and click Apply. (To adjust the Output Power, change the ALC Downlink and Uplink
Limits to the desired levels).
4. To check the Repeater’s status, click on the Status page.
5. To change the Repeater’s gain, adjust the Uplink and Downlink attenuation in equal
amounts not more than 5dB at a time and click Apply.

3.4 Troubleshooting
In case of abnormal operation, technician should diagnose abnormality via remote access or
directly connecting to repeater using Ethernet cable. If technician is required to conduct repairs
due to major alarm, repeater should first be powered off, and then technician should prepare
the proper measurement equipment before trying to fix the problem.
3.4.1 Simple Troubleshooting Method
1) Verify LED Status, both on external LED’s as well as internal module LED’s
- Normal operation: Green light on. Alarming: Red LED on.
2) Technician should check external and internal connectors to ensure all connections are tightly
secure. These connectors should be cleaned regularly.
3) If technician thinks there is a serious problem, call technical support.
