1. Security Precautions
 Only use the power supply unit provided with the Home Repeater (DC 5 V / 1.2 A). Comply
with the connection values and ratings when connecting the device to the mains.
 Protect the Home Repeater from dampness.
 Never open the device. For electrical safety reasons it may only be opened by authorized
service technicians.
 Dispose of the Home Repeater in environmentally safe manner.

Lightning protection is recommended for all installations
2. Introduction
2.1 Overview
Home Repeater is designed to improve wireless reception in poor indoor coverage areas.
Targeted as a cost effective solution for indoor coverage areas from 2,000-sq. ft. to 3,000-sq.
ft, JAS Home Repeater will allow users to operate handsets within a building or weak
coverage area while maintaining call clarity and quality.
2.2 Operational Concept
The Home Repeater takes the signal from a Pick-up antenna outside a building, amplifies it
and rebroadcasts it to the interior of the building with a Service antenna. The same process
occurs in the opposite direction taking the signal from the mobile phone and sending it
outside via the antenna and amplifier.

※Please read the following information before installing your Home Repeater.
Many mistakes can be avoided by considering over this information
3.2.1.1 Power Consumption
 The power supply of the Home Repeater accepts 110~220V, +5V, and 1.2A.
3.2.1.2 Operating Environment
 Temperature range: 0℃~+50℃
 Maximum Humidity: 95%
3.2.1.3 You need to determine the following things for the Home Repeater installation:
 A position where the pick-up antenna is to be installed:
a. The pick-up antenna should be located in a position with at least a
3’radius clear of obstructions and other radiating elements.
b. You may decide the position with checking out with the antenna level
bars of your mobile phone. If the number of antenna level bars of
your mobile phone is one or two when you check on the position of
patch antenna, it would be OK.
 However, if there is no antenna level bars on your mobile phone, you had
better change the position of patch antenna.
 You should decide the position where the Home Repeater should be installed.
a. You may install the Home Repeater on the wall or using wall mount
bracket that are provided with Home Repeater.
※When you install Home Repeater, you must consider minimum isolation
between pick-up antenna and Home Repeater.
; If there is not enough isolation insurance, the Home Repeater will be defective.
As you can see the following illustration, the Home Repeater and pick-up
antenna must be isolated from each other. If the building is made of concrete
or other signal blocking material, the isolation is sufficient.
 After you confirm the length of cable needed to connect from the pick-up
antenna to the Home Repeater, you may connect the Home Repeater and
pick-up antenna. The cable should be tied up on the wall or ceiling between
pick-up antenna and Home Repeater.

※IMPORTANT!
1. The Home Repeater is designed to be used to cover only inside of buildings. It is NOT designed
to be used to cover outside of building such as playground, open area parking lots, farmland,
and etc.
2. The Home Repeater may penetrate down to the lower floor depending on the amount of mass or
materials contained within the floor. There is no way to know whether the signal can penetrate
to the lower floor without installing another Home Repeater or additional service antenna.
3.2.2Connection
It is very important to connect The Home Repeater with antennas and cables. For
selection of antennas and cable, you may read section 6 for guidance of antennas
and cable

4 Appendix
4.1 Trouble Shooting
If Home Repeater does not operate properly after installation and the signal level of your
mobile is same as before, make sure that the installation procedures as described in this manual
were followed correctly. You may check out the following step for the inspection
4.1.1 Inspection Procedure
No. Inspection Step Remark
1 Power LED The green light should be on if the power is on.
2 Down link LED
The green light should be on, if it is normal. If
green and red light is blinked, please check next
step.
3 Up link LED
The green light should be on, if it is normal. If
green and red light is blinked, please check next
step.
4 Connection of the port
(To mobile & To BTS)
To Mobile: The dipole antenna (Service
antenna) should be connected
tightly.
To BTS: The donor antenna (Patch antenna)
should be connected tightly.
5 Cable connection to donor
antenna
The cable should not be broken or any other
damaged.
♦If the signal level of your mobile is still same as before, you might change the donor
antenna location to get better signal from base station.
♦If there is any obstacle between Home Repeater and mobile, the signal of your mobile
would be fluctuated. You may check the location of Home Repeater and re-install it.
♦If the red light in LEDs of Home Repeater is still blinked and the signal level of mobile
is same as before although you inspect them through the above procedure, you may
contact sales agent or manufacturer.

6. Guidance for Antennas and Cable
This is a guidance for customers’ selection of antennas and cables. You may read carefully and try to find
out the best type of each antennas and cables.
6.1 Antenna
When you receive the Home Repeater, you need two antennas and some length of cable. One of
the antennas is pick up antenna that is for receiving signal from outside of the building. The
other antenna is service antenna that is for transmitting signal to inside of the building.
6.1.2 Pick-upAntenna
Normally, patch or yagi antenna is used for pick up antenna that is installed outside of
building that has 7 ~ 12dBi gain. This antenna should be installed after confirmation
of line of sight. Line of sight means that the antenna should be able to see the base
station and to be located on the direction to the base station. If not, the signal is not
enough for the Home Repeater to emit to the mobile.
If you can not find a location or direction of base station, you may use your mobile
phone to confirm the position of pick-up antenna. When you see the level of antenna
level on your mobile phone, it should be at least 2 or 3 bars for the position of pick-up
antenna.
If you want to get stronger signal from base station, you may use another antenna that
has more gain such as 10dBi or 12dBi. <Figure 3> shows different types of pick-up
antennas
6.1.3 Service Antenna
Normally, patch or dipole antenna is used for the service antenna. Dipole antenna has
0dBi gain. If you would like to use patch antenna for service antenna, you might need
to use cable that you also consider the cable loss.

6.1.4 Example of using antenna
 Patch to Dipole
This is a general case of using antennas. You may use patch antenna for pick-up antenna
and dipole antenna for service antenna. You can use this antenna for small office and
home which has dimension up to (32ft x 32ft).
 Patch to Patch
You may use patch antenna for both pick-up and service antenna. You can use this antenna
for dimension up to (42ft x 42ft).
 Yagi to Patch (Dipole)
If it is not easy to install Patch antenna for donor, for instance, basement, you may use yagi
antenna for pick-up antenna.
6. 2 Cable
The RF cable is for connection between the Home Repeater and patch antenna (Pick-up
antenna). The following information is the specification of the RF cable.
Specification Remark
Model RG 58
Cable Loss 0.7dB/3.28ft
Connector type SMA type
※As much as you use the cable, there would be more loss on the cable. Therefore, you
should calculate the maximum cable length regarding antenna usage. Because the
Home Repeater has 50dB gain which is fixed.
