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.
