Features
Inside the kit
Stella Doradus mobile repeaters amplify the cellular signal from all the mobile operators, providing signal coverage
throughout the building. The external antenna receives the signal from outside and passes it to the repeater where
the signal is amplied. Then, the indoor antennas transmit the amplied signal around the building.
Description
800/ 900/ 1800/ 2100MHz
User Manual. SD-RP1002-LG_DW
The repeater must be installed as per the manufacturer’s guidelines.
The repeater has a DC short to ground built into it.
The repeater must be installed indoors in a dry environment as per all electrical equipment.
The provided power supply must be used with the kit.
The repeater must not be dismantled, or adjusted in any way. Doing so may cause an electric shock.
The repeater includes electronic components which can be damaged by static electricity.
Air must be allowed to circulate around the device. Do not block the air vents. Do not cover the repeater with anything that
inuences heat dissipation.
Install the external antenna in a location with good signal, outside and high up on the building.
Using the supplied cable, connect the external antenna to the connector on the right hand side of the repeater.
Install the repeater and indoor antenna(s) inside the building in the areas where coverage is required.
Plug the 12V power supply into the wall socket. The green signal bars on the repeater will light up (see Indicator section below).
Finally, slowly rotate the external antenna towards the operator’s mast. Check the signal bars (1-6 LEDs) on the phone inside the
house. When maximum signal bars are seen on the phone, install the external antenna in this position.

• Use the sealing tape to seal the connector on the external antenna to ensure it is waterproof.
• It is not necessary to install an external surge protector as this is built into the repeater.
• The repeater must be installed by a mobile operator.

The LCD screen explained
UL = uplink activated. The blue arrows indictate that the phone is using this band when making a phone call /
using data.
The coloured boxes with messages to the right of each band mean the following:
• ADJ - Adjusting and optimising the signal level.
• RGn - Reduced Gain. This means that there is feedback between the outdoor and indoor antenna.
Action: Ensure there is a solid wall between these antennas.
• HI - Hi power. This is a warning that the incoming signal is very strong. Action : Add 3dB manual attenuation.
• OFF - The band is switched off, either automatically, or it has been manually shutdown.
Settings - Attenuate
On this screen add attenuation to any band.
For example, if the incoming signal from the operator on band 8 is too strong,
and is automatically shutting down, add < 18dB attenuation to reduce the
incoming signal.
Settings - Band On/Off
On this screen individual bands can be turned off.
In some cases a band can be weak ( 1 or 2 bars). The phone might try to use this
band and the service might be poor. In this case, turning off this particular band
and forcing the phone to use another band can produce a better result.
Decibel page ( for Stella Engineers reference only)
• Power Up - This is the absolute signal power emitted from the phone.
• Power Down - This is the absolute signal power emitted from the cell tower.
• UL Fast AGC- Automatic gain control. This value indicates by how much (in
dBs) the repeater is attenuating the phone to an optimal level.
• AGC- Automatic gain control. This value indicates by how much (in dBs) the
repeater is attenuating the signal from the cell tower.
• Reduced Gn- (Reduced Gain) If the repeater experiences a very strong signal
from the cell tower it will attenuate the band for an extended period of time.
• Clamp - Extra attenuation in the case of a reduced gain event.
• M.Gain - Manual attenuation.

* Automatically adjusts during installation. Thereafter, automatically adjusts for seasonal variation in pathloss between the operators
tower and Outdoor Antenna.
** The uplink ampliers switch off when the repeater is not in use, thus reducing the uplink noise to almost zero. When the repeater is in
use (e.g. phone call being made), the uplink amplier switches on for the duration of the call and a blue LED switches on indicating this
is the case.
Note: Specications subject to change without notice.
