Application
The KE3700 is a fast, easy to use and a󰀨ordable multitester for the instal-
lation and troubleshooting of DSL services in hybrid ADSL1 / 2 / 2+ / VDSL2
and combined networks. With its numerous interfaces, it supports the entire
range of broadband network technology such as vectoring, G.fast, bonding,
SHDSL, Gigabit Ethernet and GPON.
Operation
The KE3700 is a powerful troubleshooting tool for quickly nding faults in
the network, outside wiring, customer devices or inside wiring. Even in hy-
brid networks where FTTH is installed, measurements can be made at any
LAN connection using the Ethernet ports of the KE3700. Because of this, the
KE3700 is the ideal solution for all broadband technologies.
Use
With its small size, robust design and intuitive operation, it is the perfect
tester for installers and service technicians. The user can perform his tasks
quickly and e󰀩ciently with automatic detection of the xDSL service and de-
nable test procedures. The large display increases operating convenience
and, when storing results, the technician has numerous options for exporting
the tests and for compiling reports.

Damage to the device resulting from inobservance will only be re-
paired for a fee!
Generally the PSU has to get plugged into the device rst
and then into the wall outlet.
Note: Please, fully charge the battery before the rst use!
The charging is completed when the charging LED changes from
orange to green. To check the charge indicator after the initial char-
ging, turn o󰀨 the device and then turn it on again with the AC adapter
connected for about 1 minute. During this time, the battery indicator
will be calibrated and now displays the correct value.

Analysis
You have the option to retrieve saved
broadband and copper measure-
ments and analyze them within the
device. In this case, not only the stored
snapshot but the whole measurement
sequence from the start of the synchro-
nization is displayed. In the selection
menu you can start the display with F2
<Info> (this can be a lengthy process
depending on synchronisation time).
You can rename a measurement le
with F3 <Edit> and delete it with F4
<Delete>. Since the display is not an
active representation of the measured
values, it is displayed with a di󰀨erent
background colour and a red border.
Address book
In the address book you can store
phone numbers, IP addresses, VoIP
access data and SIP data, frequently
used URLs as well as user names and
passwords.
You can create a new address entry
with F1 > add contacts and add the
details for the above-mentioned rubrics
in the next menu via F2.
These are then available in the corre-
sponding menus (with the key) and
you do not need to reenter the details
again.

KE-Manager Software
You can install the KE-Manager software on your PC by double clicking the
setup le within the explorer window. A windows installation wizard will guide
you through the following steps.
Connect the Multitester to your network /PC
Switch on the xDSL Multitester. Use a RJ45
ethernet cable to connect the Multitester via
the management port (100 Mb, top side of
the device) to an ethernet port within your
network or directly to an ethernet port at
your PC.
Opening the KE-Manager
Click the KE-Manager icon on your PC Desktop. The KE-
Manager opens and shows the connection status between
your device and the PC via di󰀨erent colors.
The connection status is shown at the bottom row:
– For connecting, please click on KE3x00
– KE3x00 found ==> Connection to IP 192.xxx will be established
– Connection to KE3x00 (serial number, IP192.xxx) is OK
The green background signals the established connection. The serial num-
ber and IP address are shown in the top left corner of the window. In case of
multiple KE-Multitesters plugged to the network, you can nd the desired one
using the displayed serial number. Now you can adjust the settings for the
KE-Multitester using the KE-Manager.

The KE-Manager is a exible tool to manage the KE3700 and download
saved measurement data. Like the KE3700, the KE-Manager is designed
very distinct and largely intuitive.
Conguration
Settings for several basic
options and licensing, trans-
mitter list (IPTV proles) and
the prol set can be executed
here as well as updating the
device rmware. A detailed
update guide is found under
Help in the KE-Manager.
Result Center
Provides detailed information
about the active and stored
tests. Available for xDSL,
Ethernet, SHDSL and evalu-
ation of test errors. The dis-
play of the parameters is con-
gurable individually.
Important: Always con-
nect the KE-Multitester to
the PSU before starting
the update process! An
unintentional shutdown
during the update results
in the need to send the
device in.
