User Manual MCPA Outdoor System . SET UP .1 System Set up 1) Check points before system set up a. Verification of system installation status - Electricity, In/out antenna, coaxial cable connection, and equipment mounts status. b. Verification of system accessories - User should check whole necessary accessories. c. Check receipt signal level - User should check whether receipt environmental condition is in accordance with system specification, so that system operation will be optimized.
User Manual MCPA Outdoor System .2 Troubleshooting In case of abnormal operation, technician should diagnose abnormality via remote access or directly connecting to MCPA using Ethernet cable. If technician is required to conduct repairs due to major alarm, MCPA should f irst be powered off, and then technician should prepare the proper measurement equipment before trying to fix the problem. In most cases of major MCPA, GST will simply replace the unit and conduct repairs at the appropriate facility. .2.

MPE Information Warning: Exposure to Radio Frequency Radiation The radiated output power of this device is far below the FCC radio frequency exposure limits. Nevertheless, the device should be used in such a manner that the potential for human contact during normal operation is minimized. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna should not be less than 1200cm during normal operation. The gain of the antenna is 20 dBi.
