INTRODUCTION
We advise you to read this guide first to help you get familiar
with the ScoopFone 4G in a short time. For more detailed
information, please consult the full user manual on our web
site:
www.aeta-audio.com
For this guide, we assume that the basic principles are known
and that you have already connected a microphone and a
headphone to the unit.
The ScoopFone 4G allows you to set up live mono audio
connections in three possible ways:
Standard telephone or “HD Voice” (7 kHz wide band)
link over mobile 2G or 3G networks.
Audio over IP (AoIP) connections over mobile 3G or 4G
(LTE) networks.
Audio over IP (AoIP) connections over an Ethernet wired
access.
In IP mode, up to 20 kHz bandwidth is available with the
OPUS algorithm (default algorithm). In case the remote unit
does not support this algorithm, the connection will be
established automatically with G722 or G711 coding.
AoIP connections are normally based on the SIP protocol. It is
possible to use a “Direct RTP” mode without the SIP protocol:
for such operation please refer to the detailed user manual.
This guide applies to units with firmware version 1.09 or newer.

5
SET UP
ScoopFone 4G can be operated under an ambient temperature of 0°
to 45° C (32°F to 113°F).
Installation in a 19” rack (ScoopFone 4G-R)
If needed, a rack mount tray is available for integrating one to three
ScoopFone HD-R or ScoopFone 4G-R units into a 1U space of a rack.
Powering
Before switching on the ScoopFone 4G, you need to have 6 AA
batteries inserted in the bottom compartment, or an external DC
power supply connected via the DC jack.
Batteries (Portable version only)
ScoopFone 4G works with NiMH batteries. Six 2500 mA.h NiMH
batteries provide power for more than 5 hours of transmission.
In order to get an accurate charge level indication with rechargeable
batteries, it is necessary, at least once, to leave the ScoopFone 4G on
with the external DC power until it is fully charged.
CAUTION: THERE IS RISK OF EXPLOSION IF THE
BATTERIES ARE OF A WRONG TYPE, OR ARE
INSERTED THE WRONG WAY.
DISPOSE OF USED BATTERIES ACCORDING TO
INSTRUCTIONS.
External power supply (indoor use)
The external DC supply is also used to charge the batteries. Only
NiMH batteries are supported by the internal charger. You can use
the provided LPS power adapter (GS25B12 or GST25B12), or another
adequate LPS DC power source. ScoopFone 4G runs from a nominal
12 V, but it can run with a voltage from 10 to 16 V, with a maximum
consumption of 1.5 A.
Antennas
The ScoopFone 4G uses female SMA sockets. You must connect at
least one antenna on the rear panel. A second antenna is
recommended to optimize the mobile operation. For the best
efficiency, place the antennas as far as possible from each other.
SIM card
To establish mobile links, you should have a SIM card from a mobile
telecom operator. ScoopFone 4G accepts standard size SIM cards;
use a card adaptor if necessary for supporting a micro-SIM or nano-
SIM card (Contact your dealer for more details).
Switch off the unit before inserting the SIM card
To insert the SIM card into the slot, follow the orientation marked
on the front panel (contacts facing down, cut mark forward). As the
SIM card holder is a push-push holder, you should push the SIM card
as well to extract it.
Warning: for a new SIM card requiring activation (e.g. prepaid SIM
card), you can use a mobile phone to perform the activation
procedure.
You can do the same for disabling the call waiting tone
(recommended for avoiding undesired tones during a report)

6
MAKING A CALL
Switching ScoopFone 4G on / off
To switch the ScoopFone 4G on, press for 2 seconds.
To turn it off, press for 2 s; a confirmation message is
displayed. Press OK to confirm or Esc to cancel.
Enter the PIN code
If the PIN code is enabled on your SIM card, you must enter it and
validate with OK.The PIN code can be saved using the menu.
Adjust the microphone level
Turn ON the mute LED indicator, using the mute key if
needed.
Set the Potentiometer ([1] on page 2) to its middle position (white
dot of the button in the topmost position). Adjust the headphone
balance (send/receive): enable the Fn mode and press the #key,
then set the balance to the average position with the +and –keys.
Make a test with your microphone while watching the level
indicators (above the potentiometer). If the level is too high or too
low, enable Fn mode + key 4and press key +to increase or key -to
decrease the gain of the microphone, until you get the appropriate
level.
From then on, you can use the potentiometer for fine adjustment.
Preparation: for Ethernet network (IP mode)
Connect the Ethernet Interface ([7] on page 3) of the ScoopFone 4G
to the network. If the automatic network switch is disabled, you
should select the Ethernet network through the IP / IP interface
menu.
The blue “IP” LED shows the type of outgoing call that can be set up:
LED on for the IP mode. If necessary, activate this mode using the
shortcut Fn + 3 (IP/Voice).
Preparation: for IP mode over a mobile network
If you have “Ethernet”displayed, disconnect the Ethernet cable from
the ScoopFone 4G, or force the selection of the mobile network
using the menu IP / IP interface.
The blue “IP” LED shows the type of outgoing call that can be set up:
LED on for the IP mode. If necessary, activate this mode using the
shortcut Fn + 3 (IP/Voice).
For links over the Internet via an access router with NAT,
we recommend using a STUN server. To enable it, enter
the IP / Use STUN menu.
If you use your ScoopFone 4G in IP mode with a SIP server,
you should have the icon displayed on the screen.
Preparation: for IP mode over a mobile network
Receiving mobile phone calls is always possible regardless of the
current mode; no specific setting is needed for receiving this type of
calls.
However, before setting a call in mobile voice mode, you should first
activate outgoing voice calls, using the shortcut Fn + 3 (IP/Voice).
The blue “IP” LED must be off.

7
Making a call
Enter directly with the keypad the call destination: phone number, IP
address, or SIP identifier (URI).
Press UP or DOWN to erase the last digit(s)/character(s).
Press the 0key twice to get the international +symbol.
If needed, press the #key to access the alphabetic characters.
Press the key to make the call. Otherwise cancel using Esc or
.
Using the phonebook
Enter a number as described above, and press the key to save
this number into one of the 9 memories of the current mode.
To recall a number from the phonebook, press the key and
enter the number of the desired memory from 1 to 9.
The number is displayed and you can:
Set the call by pressing the key.
Cancel using Esc or .
Edit the number using +or –
During the call
To adjust the headphone balance, enable the Fn mode and press the
#key. Adjust the balance as desired using the +and –keys.

You can adjust the transmission bit rate during an audio
connection1. Enable the Fn mode + 2 (IP Rate) key. Using the Up and
Down keys you can increase or decrease the bit rate.
Notes:
The quality bars on the screen (see [11] on page 4) provide
real time information on the transmission quality for both
directions (but for the transmit direction, this depends on
the remote unit’s capability).
If the connection is set with an AETA product at the other
end, the bit rate also changes in the receiving direction, from
the remote codec.
Hang up
Press twice to hang up.
Redial
Press the key twice to redial the last called number.
1If the link is set with the Opus coding algorithm.

How to get an HD Voice connection
To get an HD Voice connection, some conditions must be met:
Both devices involved in the connection must support HD
voice.
HD voice must be supported by the mobile network.
Usually, both units should be connected on the same mobile
network (same carrier).
Most often, 2G networks do not support HD voice. This
depends on the country or area, and the network carrier.
For this last reason, the radio technology indication (2G, 3G, 4G
display on the screen) is a useful indication that HD Voice is possible.
In addition, it is possible to force the operation to 3G mode via the
menu Mobile / Mobile network. You also have a shortcut with Fn +
1 (xG).
How to turn on/off the ringer
Enable Fn mode and press 9 key to change the ringer state.
When the ringer is off, the ringer icon on the display shows muted.
Reading SMS
Enable Fn mode and press the key to show the list of the
received SMS.
If you have got several, press OK to read the selected SMS. Press the
Esc key to keep it, otherwise OK to delete it.
IMPORTING MEMORIES
You can import a phonebook into the ScoopFone 4G using a
USB memory stick.
To do this, place a "book-scoopfone.txt" import file on the
root of the USB drive and plug it into the ScoopFone 4G after
it has started.
The import file must have the following format:
Memory number: type of memory, phone number or SIP URI
Memory number : 1 to 9
Type of memory : 0 for voice , 1 for IP
Example:
1:0,0141361268
2:0,0141361279
1:1,30000
2:1,[email protected]-audio.com
Note: importing a file completely clears the previous
phonebook; all the memories are reconfigured or erased.

Set the mobile operator APN
The ScoopFone 4G features a preset APN for each operator. You can enter another one if this
preset is not suitable, or if the operator is not included in the internal list of presets.
Note: to reload the APN from the internal list, you should erase the current one and then restart
the unit.
Line quality setting
This setting adapts the size of the reception jitter buffer depending on the expected transmission quality (the
lower quality, the bigger buffer for compensation).
“Low” is recommended for a mobile data link. The “Very high” setting provides the minimum latency, but is also
more sensitive to possible jitter on the network.
Extended menu:
There is a menu, reserved for advanced users, that also allows selecting manually the mobile network you want to connect to.
To activate this extended menu:
-Switch to IP mode if necessary (Fn key, then IP/Voice)
-Hit the following key sequence: 1 Up # # @ A E T A @ (display : @AETA@)

13
IP MENU
Note : changes made by using this menu are only effective after exiting the menu ( Esc key to go back to the upper level).
IP interface selection
With this menu, you can force the Ethernet or the mobile data network for outgoing call in IP mode. In Auto mode,
the IP interface switches to Ethernet when an Ethernet cable is connected. Conversely, whenever the Ethernet
cable is disconnected, the ScoopFone 4G switches to the mobile data network.
Set the default IP transmission bit rate (OPUS)
Here you can set the preferred bit rate for the OPUS coding, from 12 kbit/s to 192 kbit/s.
Note: this is the initial bit rate, when the link is established; afterwards the bit rate can be changed during the
transmission if the connection is done with OPUS.
Enable STUN
Using STUN is usually recommended when using a SIP server; however this is not suitable in some cases.
As a general rule, enable STUN. If you meet connectivity issues (such as failure to sync when starting the
connection, or link loss after a few seconds), disable the function.
Type of NAT (Network Address Translation)
When STUN is used, the ScoopFone 4G can detect the type of NAT performed by the router through which it
accesses the Internet. In case the router applies symmetric NAT, it is usually recommended to disable STUN.
Display the public IP address
When STUN is used, the ScoopFone 4G can detect the public IP address, with which it accesses the Internet.
Default AoIP protocol
AoIP connections normally use the SIP protocol. By selecting here “Direct RTP” it is possible to make calls without
the SIP protocol. The various parameters of this “Direct RTP” mode are available only via the embedded html
pages. The operation mode is described in the detailed user manual.

14
Change displayed SIP name
You can enter a name that will be displayed on the remote unit (depending on its type and settings).
Display your SIP account number
The SIP account data are normally entered/edited by using the web interface of the ScoopFone 4G.
Server SIP port
The default SIP port for the server is 5060. In some cases it is useful to use the alternate port 5070.
You can also set any other port value by using the web interface, or the extended IP menu (see below)
RTP port for the audio stream (display only)
This port can be changed through the web pages or the extended IP menu (see below).
Activate packet duplication (double stream)
When this feature is enabled, a double stream is sent, for a more robust transmission.
Extended menu:
Some parameters of the Audio over IP (AoIP) operation are not normally accessible via the IP menu, or they can only be read but not edited.
However, there is a mode, reserved for advanced users, that provides full access to all the AoIP parameters.
To activate this extended menu:
-Switch to IP mode if necessary (Fn key, then IP/Voice)
-Hit the following key sequence: 1 Up # # @ A E T A @ (display : @AETA@)
-Validate with the call key
From then on, the extended menu is accessible until the ScoopFone 4G is switched off.

15
TOOLS MENU
Save PIN in the ScoopFone 4G
If you select “On”, the PIN code is saved into the ScoopFone 4G and you need not enter it again
every time the unit is switched on (as long as the same SIM card stays inside the unit). If the
recorded PIN is invalid (e.g. after inserting another SIM card), the saved PIN is deleted and the
function is cancelled.
Automatic or manual answer
You can specify the number of rings before automatically answering calls, or select manual
answering.
Incoming call filtering
With “White list”, only the telephone calls (mobile voice) from numbers included in the
phonebook are accepted.
