Product Description
Amplitec C23S dual band series repeater adopts anti-interference, digital ALC, baseband
synch and GPS synch technologies, supporting built-in or external antenna.
This model is equipped with LCD screen, to clearly display parameters and working status like
the working frequency, gain, output power, ISO and ALC alarms. It is with compact size, elegant
design, weight less than 1.1KG, which help to easy installation and maintenance.
Product Features
Display shows all parameters clearly and the button function are more intuitively and faster
Support dual band network for 2G 3G and 4G
Low power consumption, low interference
Digital ALC technology, could limit the output power to ensure stable coverage
Anti-interference, auto isolation detection after start-up and auto self-oscillation elimination
technologies can avoid self-oscillation, which cause interference to the base station
Manual gain attenuation, with 1dB step to attenuate the gain among 1-31dB range

To remove alarm, if it is in smart mode, the device will make adjustment automatically after
re-powering; if it is in manual mode, you should adjust the outdoor antenna and the gain manually,
until the alarm is eliminated. If all is in OK status, that means it works normally. Press the RETURN
button back to home page after adjustment.
h. Restore Factory Default
Move the cursor to the forth line “STATUS”with UP or DOWN button (as Figure 21), then press
OK button to enter, then navigate the cursor to“DEFAULTS” (as Figure 22), press OK button to
confirm restoring factory default; factory default is under Smart Mode.

Installation Steps
This repeater should be installed on a hard, firm and flat surface, its installation steps are as
follows:
1) Select a proper installation site according to the size and installation requirements of the
repeater.
2) Estimate and mark the sites of U-shaped back holder installation holes. Drill holes with the
impact drill. Sizes of the holes are 7mm. The expected sites are as follow: (unit: mm)

10
3) Put the expansion plug(size: 8mm) into the 4 drilled holes.
4) As shown in the figure, align the fixing holes of the U-shaped back holder with corresponding
holes on the wall. Then drive 4 pcs of M6*40 screws into the expand plugs with screwdriver. Finally,
hang the repeater firmly on the U-shaped back holder.
Antenna Connection
Choose suitable outdoor and indoor antennas according to the characteristic of the coverage
area. Installation and connection of the antennas should follow the requirements as following:
1) The outdoor antenna should be installed at the place with the strongest signal and aiming
towards BTS.
2) The length of the cable, which connects the outdoor antenna and the repeater, should be less
than 20 meters.
3) Wrap the waterproof tape around the connection part of the outdoor antenna and outdoor
cable, keeping it away from water oxidation and corrosion.
4) The height difference between the indoor and outdoor antennas should be over 5m, and the
transmit direction of indoor antenna should not aim at the outdoor antenna.
5) It will be better if there is a wall between outdoor and indoor antennas.
6) Outdoor antenna should connect to BTS port of the repeater, while indoor antenna to the MS
port.

Starting
1) If possible, please wire up the grounding screw of the repeater to the ground wire of the power
line.
2) Make sure the feeder cables between repeater and antennas are firmly connected.
3) Connect the DC plug of the 5V/2A power adapter to the DC+5V port of the repeater. Then put
AC plug connecting to the nearby 220V power outlet.
4) Check if the repeater can work normally or not, by checking the operation parameters on the
screen, according to the guides of the previous “Operation and Display Description”part.
5) Test the signal intensity and call quality with a mobile phone in the coverage area.
