operation. It will output power if AGC equals to ATT. If ATT value is higher than
AGC, it shows the input signal is too strong or self excited, the device will be
protected.( By temperature compensation effect of 3-2, ATG STE, it is normal that
ATT is 10 degree higher than AGC,.) If ATT value is lower than AGC value, the input
signal is too weak; it can not output full power. The item is used to determine the
received signal strength, please check other alarm items and status when abnormal.
1-5.AGC is same to 3-1 AGC SET, it is used for comparing with ATT(1-4). Set the
AGC value manually.
1-6.TEMP Equipment current temperature. The fan controls the temperature
automatically; it operates when temperature reaches 45°C, stops rotation at 40°C,
automatically stops operation at 70°C. Unit: °C

2.Alarm
Check the alarm information of current repeater. Only view but can not be modified, it
refreshes every 0.3 seconds.
If the repeater can not operate normally, please review this alarm information to
determine the problem and investigate it one by one until the repeater operates
normally.
2-1.PRE-AMP RF IN Pre- amplifier RF input status Displaying OK/P-A RFIN
LARGE, the input signal is too strong ; A RFIN SAMLL, the input signal is too weak.
Please review 1-4 &1-5.The too strong input signal may lead to self-excitation, and
reduce the strength of signal or isolation between antennas. The too weak signal is
caused by input feeder off or antennas are not aligned to the signal resource, you can
adjust the antenna angle and check the input feeder.
2-2.PRE-AMP status Display ON or OFF. It will display OFF when other items are
protected.
2-3.TEMP temperature display OK or higher. PRE-AMP output will be cut off when
temperature reaches 70°C.
2-4.FORD POW Output power Displaying OK or P-A R OUT LARGE output power is
too large. This alarm is caused by too large output power or 3-5 low protection point
setting. You can reduce AGC value (3-1) or increase the max-output power protection

2-5.REF POW Reflection power Displaying OK or REF OUT LARGE reflection
output is too large. This alarm is caused by loose output feeder and antenna or low
reflection power protection point setting 3-6. You can check the antenna or feeder, or
increase 3-6 the max-reflection power protection point value.
2-6.MAIN DC power Power supply. This alarm is caused by power supply test
voltage is too high or too low, and inappropriate setting of too large and too small
voltage .You can check the current display voltage or test the power supply output
voltage with multimeter (1-5), adjust the voltage up-limited protection point and
voltage up-limited protection point (3-8)appropriately.
2-7.FIRSTALARM The first alarm. Record the latest alarm reason.

3-1.AGC SET Power set-up, adjust the output power of repeater.
Program version 3.3 will set the AGC to highest value in factory, hence, cannot
continue to increase; the device is different from each other. It will output full power
when reaching the highest level. It is not likely to happen that the equipment output
power exceed the standard output power.
3-2.ATG STE Temperature compensation. Enable (open) and disable (close).
Default open. Because of the equipment linearity, after temperature rises, power will
decrease by 5%. This value can guarantee that nominal power can work properly when

3-3.EXTURNATT Extra-attenuation values. Input corresponding attenuation value :
Automatic (default) The equipment will be burned due to incorrect settings
Input signal: -15~-25dB; Attenuation: 30 dB
Input signal: -25~-35dB; Attenuation: 20 dB
Input signal: -35~-45dB; Attenuation: 10dB
Input signal: <-45dB; Attenuation: 0dB
The above attenuation value applies to -15~-60 dB RF signal
strength, optical fiber received signal strength should plus 30 dB based on
RF signal strength.
This item is default as AUTO, no need to set. If it is set at a fixed attenuation, you have
to test the strength of input signal according to list above and check 1-4, the same
illustration with 1-4.
3-4.MAX input power Preamplifier output too large protection point, unit: V. This
is protection voltage (default value: 2.5V) of preamp when signal suddenly turn
stronger or produce self-excitation, no need to set and can not exceed 3.5V, or amplifier
will be burned down because of self-excitation.
3-5.MAX FORD POWER Max- output power protection point. Corresponding to
output power display (1-1), and then adjust the max- output power protection point, the
general maximum add 40%, for example, a 50 W repeater, the protection point is
70W,please increase the protection point to 85 W if the display power fluctuations lead
to frequent protection.
