- Bird Repeater system is an advanced technology system and should be handled by FCC Licensee or FCC approved staff.
- Read all documentation and warnings before handling the equipment.
- Obey all warning signs on the equipment and in documentation.
- The equipment may get hot during operation, do not operate outside permitted temperature range and keep away from heat sensitive material!
- The equipment contains ESD sensitive components. Open the equipment ONLY in a safe location designed for handling ESD products and use grounding devices! Opening the unit is not intended for field maintenance!
- The equipment contains ESD sensitive components. If not handled with care critical components may be damaged or destroyed. To avoid any damage due to ESD standard ESD precautions shall be used when handling the equipment.
- The product transmits RF signals keep away from Antennas and other radiating devices.
- Repeaters generate radio signals which are transmitted by the connected antennas. Installations should always be done so that the radiation exposure doesn’t exceed the recommendation set up by local authorities.
- Consult a FCC licensee or other applicable regulation body for details on RF requirements and safety issues on RF!
- Electrical installation shall be done in accordance with local safety regulations and laws.

Revision 2
5.2.3 RF Config
RF Config menu contains configuration fields for setting the Gain, ALC level, frequency band and the
bandwidth of the actual DMR Repeater unit.
Gain and ALC level can be set for Downlink and Uplink separately. The resolution in setting is
adjustable by the 0, 1 dB.
As mentioned the DMR Repeater unit has the adjustable bandwidth. User can set the Downlink start
and stop frequency path. The uplink path uses a fix duplex distance.
The threshold for the Automatic Level Control (ALC) is set in dBm for downlink and uplink
respectively. The ALC feature controls the gain of the repeater so that the output power never ends
up in exceeding the actual set level of the output power.
When changing any parameters a submit button must be pressed in order to send the data to the
repeater. Get button reads current set parameters.
If a different parameter (other than the specified validation range) is entered and submitted, an
Error message will be displayed on the right hand side of the configuration fields. Error message will
even show the valid range of the actual parameter.
