Epoch-S02-8002W RF Repeater User Manual V1.0 1. Installation Guide for Epoch-S02-8002W 1.1 Environmental Requirements 1.1.1 Antenna Separation/Isolation Separation between antennas is necessary to prevent oscillation. Oscillation occurs when the signal entering the system continually reenters, due to the lack of separation between the donor and server antennas. In other words, the signal is being fed back into the system. This creates a constant amplification of the same signal.
Epoch-S02-8002W RF Repeater User Manual V1.0 1.1.2 Line of Sight The donor antenna which points towards the base station typically has a narrow beam antenna pattern. As a result, a slight deviation away from the direction of the BTS can lead to less than optimum results. In addition, obstacles between the repeater and the BTS may impair the repeater from obtaining any BTS signal. As a result, the repeater cannot transmit signal to the coverage area.
Epoch-S02-8002W RF Repeater User Manual V1.0 1.2 Warnings and Hazards WARNING! ELECTRIC SHOCK Tampering with the modules within the Epoch-S02-8002W repeater exposes the user to electric shock and the risk of damaging the unit. DO NOT TAMPER with modules within the unit. Opening or tampering with any modules inside the Epoch-S028002W will void all warranties. WARNING! HIGH VOLTAGE In installing donor or server antennas, avoid close proximity to overhead power lines or high power components.
Epoch-S02-8002W RF Repeater User Manual V1.0 WARNING! Operating the Epoch-S02-8002W with antennas in very close proximity facing each other could lead to severe damage to the repeater. FCC Part 15 Class A 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.

If a soft fail alarm should occur, the alarm of concern would be highlighted in yellow.
Epoch-S02-8002W RF Repeater User Manual V1.0 In the event of a hard fail alarm, the control board will shutdown the HPA (both uplink & downlink) for 30 seconds and then turns on the HPA to check for a repeated hard fail occurrence. If the next two occurrences sense a hard fail, the control board will shutdown the HPA for 20 minutes (total of three consecutive hard fails). After 20 minutes, the HPA will automatically come back alive and the control board will check if the Hard Fail alarm has cleared.
Epoch-S02-8002W RF Repeater User Manual V1.0 The example below distinguishes the difference between an over power soft failure and an over power hard failure: The threshold value for the downlink over power parameter is set to 35.0 dBm (factory set value), a Hard Fail alarm would occur if the downlink over power value was greater than 35.0 dBm (33 dBm is the maximum composite power allowable). Similarly, a Soft Fail alarm would occur if the downlink over power value was greater than 34.
