Intelibs, Inc. Proprietary and Confidential Page 19 19  Locate the equipment with the space for the sufficient airflow to prevent build-up from the overheating. Do not compromise the amount of airflow required for safe operation of the equipment.  Verify the power connection and Fiber cables prior to turning on the systems. WARNING: Equipment loading must be verified prior to mounting the equipment on the wall or 19” rack. 3.1.1 General Safety Precautions The following precautions apply to the RHU:  The units have no user-serviceable parts. Faulty or failed units are fully replaceable through Intelibs.  When the Fiber cable is connected to the equipment, the connectors must be free from the dust and connected according to the cable manufacturer’s instructions. (WARNING: For the safety, DO NOT conduct eye-contact at the connector ends of the fibers or the port of the RHU and SRU unless equipped with protection goggle. Invisible infrared radiation may be present at the front panel of the RHU and SRU. Do not remove the fiber port dust caps unless the port is going to be used. Do not stare directly into a fiber port.)

Downloading improper images (executable file of repeater CPU) may cause harmful damages to equipment. 4.4 Additional function of RHU 4.4.1 ASD (Auto Shutdown) Function 1. If UL output power level of RHU is above the shutdown level longer than 1 second, RHU automatically turns off amplifier to protect undesirable transmission. 2. During shutdown state, monitor RU input power. If the level is below5dBfrom shut down level, turns on UL amplifier automatically.
Intelibs, Inc. Proprietary and Confidential Page 37 37 4.4.2 ALC (Auto Limit level Control) Function 1. If UL output power level of RHU reaches the ALC level, RHU decrease the output power to maintain ALC level automatically. 2. When power level goes down under ALC level, RHU increase output power until ALC ATT is 0 by 500msec ~ 1sec speed. 4.4.3 AGC (Auto Gain Control) Function 1. In order to have stable output power, RHU has AGC function that can maintain constant output power with setting output level. 2. When input level is decreased RHU increase gain to maintain continuous output level, when ALC Level Power ALC ATT = 0 ALC ATT = δ decrease ALC ATT ALC ATT = 0 Longer than 1 sec, HPA off
Intelibs, Inc. Proprietary and Confidential Page 38 38 input power is increase RHU decrease gain to have same output power automatically. 3. RHU works AGC function by 500msec ~ 1sec speed. 4.4.4 Sub-band selection Function RHU can select sub-band up to 10 bands in 65MHz bandwidth using digital filter function. These sub-band filters have very sharp cut-off characteristics and RHU can provide the signal of selected band of 65MHz BW to coverage area. This digital signal processing function also provide input signal information and antenna isolation information between link and coverage antennas. Step Descriptions If you click “Filter INFO” like following picture You can build up band pass filter up to 10 filters. Input center frequency, number of block for sub-band and click “Add” button, sub-band filter is built up. If you want to erase filter, click “Erase” button.

Intelibs, Inc. Proprietary and Confidential Page 39 39 5 Human RF Exposure and Antenna placement guide Actual distance is determined upon gain of antenna used. Please maintain a minimum safe distance of at least 40 cm while operating near the donor antennas with the maximum permissive antenna gain up to 18 dBi and 8.45 dBi for the 1710-1755 MHz frequency band. Note: According to Part 27.50 (d)(4), fixed stations operating in the 1710-1755 MHz band are limited to a maximum antenna height of 10 meters above ground.
Intelibs, Inc. Proprietary and Confidential Page 40 40 Limited Warranty Intelibs, Inc. (“Intelibs”) offers a standard two year warranty from defects in material and installation. INTELIBS may at any time exclude from this Agreement any Hardware or Software which (1) has been modified, repaired or serviced by anyone other than Intelibs’ service staff without the prior written approval of Intelibs, (2) has been subjected to unusual physical or electrical stress, whether such stress results from accident, neglect, misuse, lightning, failure of electrical power, air conditioning, humidity control, transportation, the making of specification or configuration changes requested by Customer, or any other cause other than ordinary use, and whether or not such stress is the fault of the Customer, (3) has been purchased from another Vendor and is networked, linked, attached or otherwise intended to work with the System or (4) has been moved from the place of installation. When the system has been improperly modified, repaired, stressed, used or moved as described above, Intelibs may, at its option and subject to the approval of the Customer, perform such corrective work, including any repairs, replacements and adjustments, as are in Vendor’s opinion necessary to restore the System to the condition it would have been in if subjected only to normal wear and tear at the Customer’s expense.
