Installation
Guidelines and recommendations
It is important that the repeater does not exceed the working
limits detailed in the technical specification section of this guide.
When rack mounting the repeater, ensure sufficient air flow to
prevent overheating and secure the unit within the rack system.
Cabling should be carefully routed and secured to prevent
connections becoming loose.
When desk mounted, always attach the four desk mount feet to
the repeater. The desk must have a flat level surface. The
repeater creates low level background noise and it is
recommended that it is not located in an office environment.
It is recommended that when wall mounted, it must be
positioned so that it is clearly visible to personnel to reduce the
risk of personal injury by collision. Ensure sufficient air flow to
prevent overheating. Cabling should be carefully routed and
secured to prevent a trip hazard and connections becoming
loose.
The repeater has a battery backup facility that maintains service
in the event of an AC power supply failure. It is recommended
that both AC and DC power supplies are connected to the
repeater to prevent loss of service. If the AC power supply fails,
the repeater will shut down and reboot using the DC power
supply. Time taken to reboot using the DC supply is typically 60
seconds. When the AC supply is restored, the repeater will
switch to the AC supply automatically without a reboot.
Wall-mount bracket installation
The wall-mount bracket is supplied with the following items:
Item Qty
ST6 x 35 expansion screw 6
M5 x12 screw 4
Plastic plug 6
Only attach the wall bracket to a solid wall using the fixings
supplied.
Use the bracket as a template to position the holes on the
wall. Ensure that the bracket is level. Use a small punch or
pencil to mark the position of the holes on to the wall.
Drill 6mm diameter holes on the wall in the positions marked
and drill to a depth to suit the length of the plastic plugs and
screws. Insert the plastic plugs into the holes.

Hold the bracket securely, keeping it level. Secure into
position using the ST6 x 35 expansion screws. Ensure that
the bracket is secure and level.
Remove the desk mount feet (if fitted) from the repeater.
With the top of the repeater against the wall, slide the
repeater into the bracket.
Secure the repeater to the wall bracket using the four M5 x 12
screws as shown.
Attaching the desk mount feet
If the repeater is installed onto a desk or bench, the four screw
type desk mount feet, supplied with the product, should be
attached.
Using a soft cloth or rubber mat to protect the external surfaces,
place the repeater with the underside facing upwards, onto a flat
surface.

Connections
All connectors are located on the back panel of the repeater.
Ensure that the cables are routed so that they are kept well clear
of the antenna cable.
Route cables carefully to eliminate the possibility of damage by
sharp edges. Ensure all cabling is secured and routed to avoid
the risk of a trip hazard.
AC power supply
Connect AC power supply to the 110/240V AC power input
connector.
Connect the repeater grounding point to an appropriate earthing
point.
DC power supply
The Repeater Battery Backup cable (optional) is required to
connect the repeater to the DC power source.
Connect the repeater grounding point to an appropriate earthing
point.
Connect the cable to the DC connector on the repeater.
Connect the red wire to the positive terminal on the DC power
source.
Connect the black wire to the negative terminal on the DC power
source.
If the power cable needs to be shortened, it must be shortened
from the DC power source connection end. A fuse must be fitted
to the positive line (red wire) when the cable has been
shortened. A new fuse holder must be fitted (not supplied)
because the existing fuse holder cannot be reused. The fuse
must be positioned close to the DC power source positive
terminal.
CAUTION! Failure to connect the wires to the correct terminal of
the battery or power supply may damage the product and void
any warranty.
CAUTION! DO NOT extend the Repeater Battery Backup cable.
This will affect the backup operation.
Antenna
In order to reduce the risk of RF burns, the antenna must always
remain connected whilst the equipment is switched on. Under no
circumstances should the antenna be connected or
disconnected whilst the equipment is switched on. Do not touch
the antenna when the repeater is switched on.
CAUTION! Do not operate the repeater without an appropriate
RF load attached.

Basic operation
Power on/off
To switch the repeater on, operate the Power on/off switch. The
Power on/off status indicator illuminates and the repeater runs a
start-up test routine that takes approximately 60 seconds. The
Alarm indicator illuminates for the duration of the test. On
completion of the test routine, the Analogue mode or Digital
mode indicator (depending on the selected active channel
preference) illuminates.
To switch the repeater off, operate the Power on/off switch.
Voice and data transfer
The repeater uses different frequencies when receiving and
transmitting. Received signals that are weak due to attenuation
are amplified and transmitted at a higher strength than received.
When transmitting, the repeater mode indicator illuminates. If
the repeater is transmitting an analogue signal, the Analogue
mode indicator flashes when transmitting. If the transmitting
signal is digital the Digital mode indicator flashes when
transmitting.
The frequency and DCS/CTCSS for analogue signals, is
configured using the DMR Manager software.
Alarm mode
The Alarm indicator on the front panel illuminates when certain
operational states warrant. When the repeater is in start-up
mode, the LED remains illuminated for the duration of the start-
up routine (approx. 60 seconds).
LED state Alarm condition
