8. Maintenance Guide
8.1 Confirmation of System Components
For normal operation of equipment the following should be confirmed on installation.
A. Confirm whether the repeater’s exterior would be deformed by damaged package
of repeater on delivery.
B. Confirm that the components of equipment accord and that installation place
satisfies temperature and humidity for operation of equipment defined on the
product’s specification.
C. Confirm the input signal condition of equipment defined on the product’s
specification.
D. Confirm that the state of cable and connector is good.
E. Confirm that the state of bracket of repeater is good.
8.2 Cautions on System Installation
In order for dangerous events not to occur on installation of repeater, the provided guidance
should be followed.
Especially, the power cord of this repeater is of an eternal connection type, so an easily
accessible power interruption device should be installed in the indoor wiring, and there should
be an easily accessible socket-outlet near the repeater.
Orde
r Description Cautions
1
Donor ANT welding and feeder
installation.
Service ANT or LCX equipped
• Cable should be installed without exterior damage.
• Protect connection parts like connector with insulation tape to
prevent humidity.
• Install feeder to minimize environment influence.
2 Installation of Antenna for Donor • Strongly fixed for local wind velocity to prevent antenna’s
direction from bending after installation
3 Power cable and RF cable
arrangement • Prevent cable from damaging by crooking or stretching.

9. System Set Up and Inspection
9.1 Items to be checked for Opening
A. Confirm AC 108 ~ 127 VAC common use power and power cable.
B. Check if Donor RF input signal from exterior is at normal level.
Caution※
When system operates without input signal confirmed, over-input may cause serious
damage on amplifying degauss because of saturation of output. Therefore, after
checking input signal level by equipment and ALC ON state(on shipment ALC ON)
operate equipment.
C. Put 108 ~ 127 VAC into power connector of equipment to switch ON.
D. Check Alarm LED blinking state of GUI or Repeater’s front board through laptop.
E. When it is judged that Down Link RF input signal from exterior is normal, switch
OFF the Repeater to connect ANT feed and Service ANT to Input/Output Port of
Repeater and switch ON again.
Caution ※
Conclude carefully lest Down Link and Up Link Port be reversed.
9.2 Items to be check after opening
A. Confirm existence of abnormality by checking the alarm LED lighting status of
repeaters.
B. Confirm whether the RF input/output values are normal or not by using GUI.
C. Confirm the normal operation status of repeaters by measuring the characteristics,
etc. of spurious waves of the repeater’s down link and up link output using a
spectrum waveform analyzer by using a coupling terminal beside each input/output
port of the repeater after about 10 or more minutes passes after turning on the
power of repeaters.
D. Optimize the electric wave environments while comparing with the status before
opening about whether there is no electric wave shade region or non-
communicable region by measuring the communication quality in the service region
using a terminal or gauge after normal operation of the repeater.

9.3 Failure and Inspection
9.3.1 Inspection of Repeater
On routine or emergency service of repeater the following orders should be taken to check its
failure.
A. Check RF input/output level and LED of repeater using Web GUI. On routine service
check calling quality with terminal or measurer, or on emergency service the
following should be taken even if RF input/out level of repeater on Web GUI is
normal.
B. Connect link harmonic analyzer to test terminal of repeater to confirm output state.
C. Use Coupling port to check output value.
D. Check if the output value of repeater obtained by harmonic analyzer agrees with
actual out put value of repeater.
E. Check input level of repeater when the output value of repeater obtained by
harmonic analyzer does not agree with actual output value of repeater.
F. When input level is not same as the one on installation time showing distinct
difference, check antenna welding state and feeder’s installation state.
G. If the output value of repeater is abnormal as comparing input level to operation
gains of repeater, switch ON/OFF the repeater to check the output state with
harmonic analyzer. On severe failure immediately replace with spare parts to supply
normal service.
