every 0.3 seconds.
1-1 AGC ready status. The machine will detect the strength of input signal and adjust
the attenuation value automatically after turning on .READY will be shown after 5
seconds, if there is no alarm, it can work properly. If it shows NOT READY, and
without any other alarms, please reviews 1-4, the input signal might be too weak or too
strong. Please restart the repeater if signal strength changes.
1-2 FOR D POW Current output power display Unit: W
1-3 REF POW Current reflection power display Unit: W

1-4 ATT Corresponding to the AGC value in 1-5, is the value of current
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

Notes:

Please switch off the equipment when changing the SIM card. The equipment can be

turn on when SIM card is correctly inserted and the cables are well connected. If you
can not make calls or receive text messages, please check the connection of the socket
in GPRS module, possible overdue GSM card bill, or the loose connection between
antenna and other cables. If you can make calls but can not receive the messages, which
might indicate weak signal and strong disturbance, please check if the antenna and
feeder of GPRS are in near distance with output port and feeder of the repeater, which
should be set far from repeater antenna. If the GPRS doesn’t work after being se up by
the steps above, or the signal is too weak and interference is too strong, an extension
cable with length of 10 meters should be added to the output interface of GPRS module.
Try to keep the GSM antenna away from repeater transmitting antenna. Use waterproof
tape to cover the connectors. If the signal is normal, there is not need to add 10 meters
extension cables, which will cause attenuation to GSM signal.
If there is no GSM mobile signal nearby, GPRS function is not available.

It takes about 2 minutes for the GPRS to get started. Please check short message later
on. It is normal that the monitor module may fail to work properly in 10 seconds while
repeater is sending message. It is internal protection mechanism. Everything will be
operated properly when the message is done.
