Preface
Thank you for choosing a model in the Willtek 4100
series. The equipment will give you valuable assistance
in functional testing and troubleshooting on GSM
mobile phones.

Willtek 4107S The Willtek 4107S offers a number of additional
features compared with the Willtek 4107 (see chapter 5
for details). The S version can be identified by the type
label and the model name in the start menu.
Willtek 4107L Special inexpensive model only available bundled with
other products (eg 4192 GSM Phone Checker
software). The same range of functions as the
Willtek 4107, except that FAULT FIND mode is not
available. This model can, however, be remotely
controlled (see chapter 5). Please contact our Sales
department for details.
nOperating modes
[AUTOTEST] Fast and accurate full testing of a mobile phone with an
overall assessment of PASSED (mobile phone OK) or
FAILED (mobile phone defective). Largely automatic
testing requiring no system expertise on the part of the
user.
[FAULT_FIND] Operating mode for error location on defective mobile
phones (not available for Willtek 4107L). Selective
performance of individual tests. Displays
measurements for assessment by experienced users.

&This User Guide is applicable to all models in the
Willtek 4100 series. The generic name 4100 is used
whenever the Guide refers to features which are not
specific to a particular model.
Do you speak English? The testers have a display which can show text either
in English or in some other language. This Guide
assumes that you have selected English, in which case
the illustrations and instructions will match up with what
you see on your tester's display.
If some other language is selected, the Guide and the
display no longer match up. In that case either translate
what the Guide says into the other language or switch
the language to English for a short period (see also
page 2-3).

Initial startup
All you need to do to start up your Willtek 4100 the first
time round is connect it to the power via the
accompanying power supply unit.
nAttaching the power supply unit
!Plug the 8-pin connector coming from the power supply
unit into the matching socket on your Willtek 4100.
wWhen plugging the connector into the socket, be
sure to observe the mechanical coding on the
socket and the connector. If these do not match,
the connector will not fit into the socket. Do not
use force! Use only the original power supply unit.
"Connect the power supply unit to the wall power outlet.
§Press the on/off button to switch your Willtek 4100 on.
nStart menu
Immediately after being switched on, the Willtek 4100
briefly displays an initialization menu (in this period
among other things the operability of the device is
checked).
The tester is fitted with a maintenance-free fan in order
to keep the semiconductor components cool. The level
of noise produced by the fan is normal.
Once you see the start menu (picture on left), the
device is ready for use.
The first time you start up the device, you should at this
point press the [SETU ] key to adapt the basic
configuration of your Willtek 4100 to match your
specific requirements (see Chapter 2).

Basic settings
ï[SETU ]
As a rule, the basic settings need only be configured
once during initial startup. A powerful capacitor ensures
that the settings and the stored test result are
preserved when your Willtek 4100 is off.
+The tester should be on for about 4 hours at
least every 14 days (for capacitor charging) to
ensure that no data is lost.
Contrast
ï[SETU ] +Adjust contrast +[ENTER]
To adjust the readability of the display to the ambient
conditions.
!Using the cursor keys, alter the contrast to produce
optimum readability from the normal viewing angle.

Willtek 4100 Basic settings

Printer
ï[SETU ] +Printer +[ENTER]
To select a printer for outputting test results.
!Using the cursor keys, select the manufacturer of your
printer (EPSON or HP). Printers from other
manufacturers can also be used, provided that they
have an HP or Epson emulation available. Select ASCII
if your printer is neither Epson nor HP-compatible.
+All printers which do not require the use of a
driver under DOS can be used directly. More
recent Windows printers are therefore generally
unsuitable. Printers of this type can, however, be
used to print exported test logs from the PC (see
page 6-16).
"Confirm your selection with [ENTER].
Setting the page length
The value you specify for Lines per page determines
the number of printed lines per page (including blank
lines at the top of the page) when you print test results.
Once this number of lines is reached on the printout,
the tester issues a form feed. The specification you
make for Free lines at top sets the number of blank
lines at the top of the page (if, for instance you want to
avoid overwriting a letter header).
!Move to the entry fields with the cursor keys, enter the
required value and confirm every entry with [ENTER].
"Return with [ESCA E].
+For information on connecting a printer to your
Willtek 4100 and on printing test results, refer to
page 6-5.
Basic settings Willtek 4100
2-4
Press the {PRINT} key to print a test
page using the current settings
(see also page 6-6).
Example of page length
Lines per page = 59
Free lines at top = 9
Nine lines will remain blank at the top
of the page. This means that a total of
50 lines will be available on each
page for the test results (59 - 9).
Whether these will fill the entire page
or not depends to a large extent on
the font settings on the printer, since
the Willtek 4100 just outputs the
characters.
The way in which the characters
appear on the paper (font, size, line
feeds) is determined by the printer
on the basis of the settings made
on the printer. This means that you
can only change the appearance of
the test results by changing the
printer's settings.
