Connect the equipment frame ground to the building ground. Operating the CAT-5 DAS with antennas in very close proximity facing each other can lead to severe damage to the repeater. RF EXPOSURE INFORMATION A minimum separation distance of 7.9 inches (20cm) must be maintained between the user and the external antenna of the repeater to satisfy FCC RF exposure requirements. For more information about RF exposure, please visit the FCC website at www.fcc.gov This equipment is for indoor use only and enables the communication wiring to communicate inside the building. 2 Contents 1.

MHU MHU Link Status iDEN Control window is appeared if iDEN checked and CDMA Control window is appeared if 48 CDMA checked. Link On/Off : Port On if Link On/Off box checked, if not, Port Off If EHU is displayed with Link On and turn green light on at the Link status, it means that EHU is connected to Port. (If RU is displayed, it means that RU is connected to MHU.) If UKN is displayed with Link On and turn red light on at the Link status, it means that not connection. If communication is failed with Link on, turn red light on at the Link status. If Link Off, turn gray light on at the Link Status. iDEN Control Page ① Path Control : DL or UL Path On/Off ② Power Status : DL Input/ Output Power and UL Output Power display ③ Power Control ALC(Automatic Level Control): DL ALC operates only and ALC Level is 5dBm. Manual Gain Control: If ALC Off, DL and UL Gain is able to set up. If ALC On, gain setting is impossible because gain controlling function is inactive. ④ Up Link Gain Control: If the UL Gain Tracking is ON, the DL and UL will link so that the UL 49 tries to match with the DL by the UL Gain Offset value. If the UL Gain Tracking is OFF, the DL and UL will work individually. (If ALC On, UL Gain Tracking is On automatically. UL Tracking On/Off function is inactive, Basic Gain deviation of DL and UL is -10dB at MHU) ⑤ ASD(Automatic Shut Down): MHU exists UL ASD only. If UL Output Power maintains for 3 seconds(ASD Time) at the ASD Level, it occurs Shutdown. If Shutdown is repeated 5 times(ASD Count), Easy Max Setup is needed. ⑥ Return To Factory default: Initialize function ⑦ Easy Max Setup: If Easy Max Setup executes, execute after all linked systems initializing.

The manufacturer whose product is working in this frequency band is obligatory to prove the harmfulness of his product. In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC), and the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, Page 1 of 3 The antenna of the product, under normal use condition, is at least 20cm away from the body of the user. Warning statement for keeping 20cm separation distance and the prohibition of operating next to a person has been printed on the user's manual. So, this product is classified as the Mobile Device. According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency(RF) radiation as specified in 1.1307 (b). LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) - Class A Frequency Range (MHz) 0.3 - 3.0614 0.3 - 1.34614 61.4 LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) - Class B 30 - 30027.5 300 - 1500- 1500 - 100,000- 4. Friis Formula Friis transmission formula : P d = (P out *G) / (4*π*r 2 ) R= The maximum Gain measured in Fully Anechoic Chamber is 3.00 dBi or 2.00 (numeric). P out = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 MODE: iDen (QAM) Pd is the limit of MPE, 1mW/cm 2 . If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached.
