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.
Safety Issue Remind
To ensure the cell booster operating temperature range is in
59°~113°F(15~45°C)indoor environment.
Do not connect the booster directly with any cell phone/device, this may cause
damage to the cell booster.
Remain at least 4ft of the cell phone/device from the booster at any time.
For RF safety , both outdoor and indoor ANT are not allowable and must be at
least 8 inches (20cm) away from all personnel.
Changes or modification are not allowable and made without approval by
ClearCast will avoid warranty.
Installation of the outdoor antenna must be under the protection area of a
lightening rod, or the users can use a lightening arrestor on the outdoor antenna
connector to enhance anti-lightening damage capability. However, ClearCast
warranty does not cover lightening damage.

procedure / step and install
improperly
.
If device does cause harmful interference to radio or TV reception , the users must turn
off the power of cell booster and reset the power after the following one or more
procedures:
● Tune / adjust the outdoor ANT direction / location.
● Increase separation distance between outdoor ANT and the cell booster.
● Consult your dealer for assistance.
● Consult the CATV / SATV / TV / Ham radio expert for assistance.
