Opening or tampering the AXM700-9543 will void all warranties.
WARRANTY
Actual separation distance is determined upon gain of antenna used.
Please maintain a minimum safe distance of at least 50 cm while operating near the donor and the server antennas. Also,
the donor antenna needs to be mounted outdoors on a permanent structure.
RF EXPOSURE & ANTENNA PLACEMENT Guidelines
Operating the AXM700-9543 with antennas in very close proximity facing each other could
lead to severe damage to the repeater.

2.2 Ethernet Port and Host/Remote Switch
Figure 2-2 Ethernet Port and Host/Remote Switch
2.2.1 Ethernet Ports
• Modem – The Modem port is to only be used when the optional internal modem box (Digi Transport-WR21) is
used with the repeater. This port directly connects to the Ethernet port of the internal modem box. If a Digi
Transport WR-21 is being used with the repeater, used the included RJ-45 jumper cable to connect the Local
and Modem ports together and then flip the Host/Remote switch to the Remote position.
Advanced RF Technologies, Inc. 17
• Local – The Local port can be used to communicate directly with the AXM700-9543 using a RJ-45 crossover
cable or can also be used to connect the AXM700-9543 to an external modem box or the optional internal Digi
Transport WR-21.
Advanced RF Technologies, Inc. 18
2.2.2 Host/Remote Switch
The Host/Remote Switch allows the user to switch the default Repeater IP, Subnet Mask, and Gateway of the
repeater to an alternative setup. These settings can be adjusted by logging into the repeater in HOST mode and
configuring the settings under the Modem Box Setting section on the Install Page (section 5.4.4).
Once the settings are set, flipping the switch to the REMOTE position will reboot the repeater with the new
alternate settings. Please note that when the repeater is set to the REMOTE position, DHCP is disabled and the
repeater will not automatically assign an IP address to any device that connects directly to the repeater.
• Host IP: 192.168.63.1 (Fixed IP, unable to modify this IP address)
• Remote IP: 192.168.63.5 (Default IP, but can be modified in Host mode)
2.2.3 AC Power

The AC Power on/off switch and AC selection switch are located at left of PSU. The AXM700-9543 PSU can
operate at 110V AC and 220V AC. The user should verify that the AC input voltage selection switch is set to the
correct voltage before powering on the AXM700-9543.
2.2.4 Back Up Battery Port
Figure 2-5 Battery Backup Port
The AXM700-9543 can be connected to an ADRF-BBU (ADRF Battery Backup) to provide power during a power
failure. If an ADRF-BBU is utilized, connect the ADRF-BBU to the AXM700-9543 via the external battery port.
(WARNING: The circuit switch on the ADRF-BBU must be set to OFF before connecting the ADRF-BBU to the
AXM700-9543 to prevent damage to the repeater or the ADRF-BBU and personal injury.)
Note: Please contact ADRF Technical Support for assistance if you are unfamiliar with the installation
procedure of our battery box.

Advanced RF Technologies, Inc. 23
4.3 Antenna Separation/Isolation
Separation between the antennas is necessary to prevent oscillation. Oscillation occurs when the signal
entering the system continually reenters, due to the lack of separation between the donor and server antennas. In
other words, the signal is being fed back into the system. This creates a constant amplification of the same signal.
As a result, the noise level rises above the signal level.
Figure 4-3 RF Repeater Oscillation
To prevent feedback, the donor and server antennas must be separated by an appropriate distance to provide
sufficient isolation. Isolation is attained by separating antennas a sufficient distance so that the output of one
antenna does not reach the input of the other. This distance is dependent on the gain of the repeater.
A sufficient isolation value is 15 ~ 20dB greater than the maximum gain of the repeater. For example, if the
gain of the repeater is 50 dB, then an isolation of 65 ~ 70dB or greater is required. In the same manner, because
the AXM700-9543 has a maximum gain of 95dB in case of AXM700-9543, it requires isolation of at least 110 ~
115dB.
Advanced RF Technologies, Inc. 24
4.4 Line of Sight
The donor antenna which points towards the eNode-B typically has a narrow beam antenna pattern. As a
result, a slight deviation away from the direction of the eNode-B can lead to less than optimum results. In addition,
obstacles between the repeater and the eNode-B may impair the repeater from obtaining any eNode-B signal. As a
result, the repeater cannot transmit signal to the coverage area. Therefore, a direct line of sight to the eNode-B for
the donor antenna is vital to the function of a repeater. For the same reason, placing the server antenna in direct
line of sight of the coverage area is also necessary.

ϴ. APPENDIX
ϴ͘1 Shutdown Retry Logic
The function of the built-in shutdown routine is to protect the repeater from any further damage from a hard-
fail that the system may be experiencing.
Within 5 seconds of a hard-fail alarm being detected, the repeater will start the shutdown routine. The
repeater will shut down by powering of the HPAs (high-powered amplifiers) for 30 seconds.
After 30 seconds have elapsed, the repeater will power on the HPAs and check to see if the hard-fail alarm still
exist. If the hard-fail alarm still exists, then the repeater will shut down for 1 minute (double the time of the
previous shutdown time).
After 1 minute has elapsed, the repeater will power on the HPAs and check to see if the hard-fail alarm still
exist. If the hard-fail alarm still exists, then the repeater will shut down for 2 minutes (double the time of the
previous shutdown time).
The shutdown routine will repeat itself a total of 10 times. If the hard-fail alarm still exists after the 10th retry,
then the repeater will turn off its HPAs permanently until a reset is performed or factory set is executed.

Warning: Exposure to Radio Frequency Radiation The radiated output power
of this device is far below the FCC radio frequency exposure limits.
Nevertheless, the device should be used in such a manner that the potential
for human contact during normal operation is minimized. In order to avoid
the possibility of exceeding the FCC radio frequency exposure limits, human
proximity to the antenna should not be less than 400 cm during normal
operation. The gain of the antenna is 16.0 dBi.The antenna(s) used for this
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
