2 Gain Setup
2.1 iDEN 800
9 TX Gain: 80dB, RX Gain 80dB
2.2 iDEN 900
9 TX Gain: 80dB, RX Gain 80dB
* Please, turn off the ALC and ASD by the commands “TXALC OFF”, “RXALC OFF”,
and “ASD OFF” before the gain setup.
Factory defaults are specified in ALC ON and ASD ON.
While the ALC and ASD are on, the gain setup is not available and an Error
may be occurred.

3 ALC (Automatic Level Control) Level Setup: 30dBm
* ALC (Automatic Level Control) maintains the specific TX and RX output power by the
setup parameter. Do not set the ALC value over 30.
4 ASD* (Automatic Shut Down) Setup:
9 Level: 33dBm, Time: 3sec, Count: 10
5 Tx HPA On
6 Rx HPA On

* If the output power gets higher than “ASD_LEVEL”, the repeater will shut
down for “ASD_TIME” time and then turn on the amp and measure the
output power again. If this repeats “ASD_COUNT” times, the repeater will
shut down completely.

5. Troubleshooting
5.1 RF Connection Check
Problem
Either the downlink output power or the uplink output power (=Input
Power to the repeater) is too weak.
Solution
Check if the following RF connections are loose:
1. The cable connection from the donor antenna to the donor
antenna port
2. The cable connection from the service antenna port to the
service antenna
5.2 Power Connection
Problem
All LEDs at the bottom are turned off.
Figure 17. LEDs Off
Solution
Check if the power cord is connected correctly and the green LED at the
bottom is on.

5.3 Red Light on the Alarm LED
Problem
Red light LED turns on the Alarm LED after applying AC power.

User’s Manual -39-
* Check points
The red LED can be turned on due to out of range as the following below:
Alarms Lower Upper
Tx Input -70dBm -30dBm
Tx/Rx Output 0dBm 35dBm
Temperature -10°C 80°C
DC Voltage 20V 30V
DC Current 0A 5A
Solution
If the red light LED is steady in the range of critical values, request a
technical support.

6. Glossary
6.1 ALC (Automatic Level Control)
* ALC feature prevents the repeater from exceeding its maximum output power,
by reducing the gain automatically.
ALC is used to adjust the gain to an appropriate level for a range of input signal
levels.
[Example]
[For the repeater with 30dBm Maximum Output power, 80dB Maximum Gain /30dB
Gain control range, ->
If input signal is -30Bm and ALC is set as 30dBm, the gain will be 60dB to adjust to
the level.
If input signal is -55dBm, the output power will be 25dBm by the limitation of the
maximum gain even though the ALC is set as 30dBm.]
6.2 ASD (Automatic Shutdown)
* Automatic shut down protects the repeater itself from the oscillation or excessive
input signal and eliminates any degradation to the network.
There are three parameters, ASD_LEVEL, ASD_TIME and ASD_COUNT.
If the output power gets higher than “ASD_LEVEL”, the repeater will shut down for
“ASD_TIME” time and then turn the amp back on and measure the output power
again. If this repeats “ASD_COUNT” times, the repeater will shut down completely.
[Example]
[For the repeater with 30dBm Maximum Output power, 80dB Maximum Gain /30dB
Gain control range,
Assuming ASD_ LEVEL: 35dBm, ASD_TIME: 3sec, ASD_COUNT: 3
If the output power is 35dBm [ASD_LEVEL] and higher for some reasons,
the repeater will have shut down for 3 seconds [ASD_TIME]. If this repeats 3 times
[ASD_COUNT], the repeater will shut down completely.]
