TABLE OF CONTENTS 
 
 
1.  Safety and Environmental 
 
The electrical installation has to be performed in 
accordance with the safety regulations of the local 
authorities. Due to safety reasons, the electrical 
installation must be performed by qualified 
personnel only. The repeater must not be opened. 
The antennas of the repeater (integrated and / or 
external) have to be installed in a way that the 
regional and national RF exposure compliance 
requirements are met. 
To comply with FCC RF exposure compliance 
requirements, the following antenna installation 
and device operating configurations must be 
satisfied: A separation distance of at least 20 cm 
must be maintained between the antenna of this 
device and all persons. RF exposure compliance 
may need to be addressed at the time of licensing, 
as required by the responsible FCC Bureau(s), 
including antenna co-location requirements of 
1.1307(b)(3). Maximum permissible antenna gain 
is 12 dBi. 
 
The miniRepeaters must only be used for 
indoor applications! 
 
 
2. Quick-Start Checklist 
 
† Adjust channel(s); see chapter 10
† Mount the repeater; see chapter 6
† Install donor and coverage antennas. 
† Provide the repeater with power; see chapter 3
† Adjust the attenuation; see chapter 12.  
Start the adjustment with the maximum attenuation 
and decrease attenuation until the ALC becomes 
active and the ALC alarm LED lights up. Then 
increase attenuation until the ALC alarm is inactive 
again. 
or 
† Select auto-setup; see chapter 12
† Check for alarms; see chapter 13
 
3.  RF and Power Connectors 
 
G0783ZR
 
 
The miniRepeaters are equipped with two RF antenna 
ports: one antenna port that provides RF signals 
to/from mobile(s) and another antenna port on the 
opposite side of the miniRepeater that provides RF 
signals side to/from the BTS. Both of these 
connectors are SMA-Female. Two coaxial jumper 
cables are included with the miniRepeaters to provide 
N-female connection ports. 
 
The socket for the DC supply is situated to the right of 
the “to/from BTS” RF connector. The power supply 
voltage for this connection point is 6.7 to 7.5 VDC, 
with a typical current draw of 1.7 amps. Only the 
Power Supply Unit (PSU) supplied with the 
MiniRepeater must be used. 
 
An alternative method to provide power to the 
MiniRepeater is through the “to/from BTS” RF 
connector via the coaxial cable and a bias-T at the 
source. The DC socket of the repeater must not be 
connected if the unit is biased via the RF port.
