D
Minimum Separation Distance Limitation
● Allow more than
20ft (6m)
direct separation distance between the outdoor ANT and
cell booster to avoid the loop oscillation to cause the booster to shut down with any
1 or 2 blinking LED.
● The users must
remove the DC plug
from the DC jack of the cell booster
immediately
and tune/adjust the outdoor ANT direction/location. You may need to
lengthen the direct distance between the outdoor ANT and cell booster. Re-plug the
DC plug to the DC Jack of the booster as
reset
, verify these 2 LED lit solid red
and/or green.
● Verify that the 2 LED lights are lit (red or green), not blinking (LED solid lit is a
must
requirement
for this booster in normal operation).
● If it is still blinking in any 1 or 2 LED , the users must remove the DC plug from the
DC jack of the cell booster, repeat tuning/adjusting the ODANT for each cycle, then,
reset the DC power of the cell booster
until the 2 LED lights
indicate solid red
and/or green.
● The users may further tune/adjust the direction/location to find the best reception.
(see
P.4
)
E
LED Indication
● At any condition, the 2 LED lit
remains solid Red or Green
which represents the
cell booster in normal operation.
Solid R LED:
The outdoor ANT captures insufficient outdoor cell tower signal level,
smaller indoor service area. If far away for cell tower, it could be solid red only.
Solid G LED:
Sufficient outdoor cell tower signal level was captured by the outdoor ANT,
larger indoor service area
improving
the service quality both voice and mobile internet.
● If any 1 or 2 LED lights are still blinking , either red or green must be avoided:
R LED blinking:
Loop oscillation shuts down the cell booster and no longer enhance the
reception, the troubleshooting procedure see
P.9
.
G LED blinking:
The outdoor ANT captures excessive signal level, and shuts down the
cell booster. Generally, indicates the house is near the cell tower. The users must
tune/adjust the outdoor antenna direction/location away from the cell tower to prevent the
excessive reception. (See Abnormal operation of troubleshooting,
P.10
)
and 3rd Q&A of frequently asked questions,
P.11
)
※
To tune / adjust the outdoor ANT direction / location to
allow
the 2 green lights to
become solid which allows the best reception both voice and mobile Internet and larger
indoor coverage. (Detailed tuning procedure see
P.5
)
※
In fringe area, the cell booster may still be 1 or 2 solid RED LED even after after
carefully tuning/adjusting the outdoor ANT, that is the users allocation is far away from the
cell tower for the RED LED band.
Anyway, operationl status in solid RED LED, the users must still tune/adjust the
outdoor ANT direction/location to get a better reception. (Better service quality
and larger indoor service coverage in the fringe area.) (see P.5)

Troubleshooting
The users may
verify
the color of these 2 LED of the cell booster as an indication of
the operational status. Users should follow the LED indication to solve the problem.
Normal operation:
These 2 LED lit solid Red or Green, non blinking:
● 2 LED in solid RED but poor reception:
Tune / Adjust the outdoor ANT direction / location as shown in
P.5
to increase the incoming
cell signal level which may improve both voice and mobile internet service coverage and
quality.
※
If the location of the residential house in fringe area like far away from cell tower or
mountain area, valley, it may cause poor reception after carefully tuning / adjusting the
outdoor ANT.
● 2 LED in solid Red but no reception:
Check all the connection are well connected as below:
a.
Outdoor ANT + RF A RG-6/U coaxial connector
b.
RG-6/U coaxial con outdoor ANT connector of cell booster Indoor ANT
c.
Connectors cell b Indoor whip ANT
d.
RG-6/U coaxial con RF A RG-6/U coaxial connector if the 17ft
optional extension cable connection is used.
※
The users should power off and on
again
(Reset the power,
P.3
) the cell booster to
ensure whether the new status is fine after any improvement procedure.
Abnormal operation:
Any 1 or 2 LED blinking either Red or Green
● Blinking 1 or 2 RED LED: It is loop oscillation shut down. The users must turn off
the DC power of the cell booster. Tune/adjust the outdoor ANT direction/location
and / or extend the separation distance between the outdoor ANT and cell booster.
Reset the DC power of the cell booster until the LED is in normal operation status.
● Blinking Green LED indicates the outdoor ANT is facing toward proximity of the cell
tower which captures excessive signal level. The users need to tune / adjust the
direction / location of the outdoor ANT away from proximity of the cell tower and use
the wall blockage of the residential house to reduce the excessive cell signal level of
the proximity of cell tower and reset the cell booster.
2 LED non lit:
● To verify the 110VAC power socket / strip first.
● If the AC power socket / strip is normally working, check the AC-DC Adaptor
connection both AC or DC plug to ensure the power deliver to the cell booster.
● If the AC-DC Adaptor cannot deliver the DC power to the cell booster, consult your
dealer for a new AC-DC Adaptor.
Q:
How will the weather affect to the cell phone indoor reception?
A:
Sunny or cloudy day will not affect the indoor reception. Rainy, snowy, foggy day
will reduce the indoor reception coverage, especially heavy rain, snow, fog may affect
more. Also, the rain, snow, fog has more influence on PCS Band for its higher
propagation loss than cellular band.
Q:
Why the loop oscillation is the most
important
issue for a cell booster
installation? How can I verify and prevent from it?
A:
The loop oscillation not only causes the cell booster to no longer serves the user’s
link and
not enough
distance separation between the outdoor ANT and booster.
The users may check the 2 LED on the booster as the status indication of loop
oscillation. Any 1 or 2 of the RED lit is blinking indicates loop oscillation of the cell
booster. Remove the DC-plug from the DC jack of booster immediately, and follow the
improvement procedure shown in
P.5 or 6
until these 2 LED lit either solid Red or Green.
Q:
If my house is nearby the other operator’s cell tower and my cell operator’s tower
is far from my house. How can I install and prevent the excessive signal level coming
from the nearby cell tower?
A:
First, you should turn away the outdoor ANT direction from the nearby cell tower
and choose another direction/location, also, by using the house wall as the blockage of
the nearby cell tower.
Q:
Can the cell booster serve multiple users simultaneously?
A:
Yes. The booster is designed for the multi-users operation for it is linear
amplification and controls the overall power as well as blocking the interference of the
cell tower.
Q:
Can the cell booster help Wi-Fi reception?
A:
No. It cannot help the home Wi-Fi reception for they are different frequency band
between the cell band and Wi-Fi band.
Q:
Does this cell booster help 4G700 and AWS band?
A:
No, the cell booster only helps 800 (cellular) and 1900 (PCS) band.
All the mobile operators in 800 and 1900 band may be increased the reception inside the
house by this booster.
Q:
Is the cell booster helpful or harmful for human health?
A:
It is
helpful
for human health by installing the cell booster.
The cell booster makes the cell phone radiates lower RF power to cell tower than not
using a cell booster inside the house. The lower RF power radiated from the cell phone
is not only helpful for human health also extend the battery life span.
Q:
Why do we use a panel ANT instead of an omni-directional ANT?
A:
The panel ANT is a directional ANT which captures more cell signals from tower
than the omni-directional ANT. That makes the panel ANT offers better service quality
and larger indoor service area.
