Chapter 3: Admin & User Mode
Introduction
WF28 PDA has two distinct modes of operation: Admin and User Mode.
In admin mode, system administrators or field service technicians have full rights to configure system settings
and install / un-install applications. This is a mode typically used for initial stage of setup & ongoing
maintenance.
The user mode, as its name implies, is specially designed for end users who use WF28 PDA as a dedicated
working terminal or appliance. As system configurations are completely hidden in user mode, e.g. IP address,
Wi-Fi keys, application shortcuts & etc, system integrators (SIs) would find deploying WF28 much fewer
support calls in compare with deploying consumer based PDAs. Since users have no way to gain access to
file system in this mode, no files or local database can be tampered or taken out of the device. Therefore,
data security could be enforced effortlessly.
The desktop / program shortcuts could be customized independently in admin and user mode. Standard
control panel features in admin mode would be reduced in user mode. See the diagrams below for the
differences
Admin Mode User Mode
Start menu & desktop shortcuts could be configured to look differently in admin and user mode
In user mode, only a limited set of control panel features are available.

Admin Login & Default Mode
A brand new WF28 is pre-configured to run as admin mode. All features can be accessed without restriction.
To configure default boot up mode, follow the steps below:
Admin Login
Open battery cover
Locate the reset button (near top left hand corner of battery)
Turn off PDA
Press and hold power key, then quickly lightly press the reset button
Keep holding the power key for 1 seconds and release
Admin login screen is shown
Default admin password is 12345678 (password can be changed by
administrator)
NOTE: Admin password should not be disclosed to end users.
Admin Menu
At the bottom screen, it shows “Default mode is admin”. Therefore,
every reboot of PDA would start as admin mode
To change default mode as user, select “Change default mode”
If administrator needs to go to user mode once to examine the user
mode settings, simply tap “Start OS (User Mode)”. Note that this will
not change the default mode.
Similarly, if default mode is user, administrator may go to admin mode
once by tapping “Start OS (Admin Mode)”

Customizing Admin / User Mode Shortcuts
Program shortcuts displayed in desktop or Start > Programs can be customized independently in admin & user
mode. Typically, user mode may contain only one or two application shortcuts. Some special shortcut
folders for different purposes are listed below:
Shortcut Purpose Admin Mode User Mode
Desktop shortcuts
(Shown on top of wallpaper)
\Windows\Desktop \Windows\Desktop_user
Programs shortcuts
(Start > Programs)
\Windows\Programs \Windows\Programs_user
** Auto startup programs, e.g. background
process \Windows\Startup \Windows\Startup_user
** NOTE: some system level programs placed in both \Windows\Startup & \Windows\Startup_user should not
be deleted: MsrIconControl.exe, ReadSysInfo.exe
autorun.inf
Configuring a large of no. of PDAcould be a time consuming task. With this in mind, WF28 is specially
designed to enable autorun of designated program when SDCard is inserted. For example, autorun
application setup program when SD Card is inserted.
The autorun.inf is a plain text file that must be placed at the root directory of a SD Card. The format is as
follows:
[autorun.inf]
Open=XXXX
Where XXXX is the program to run. Note that XXXX cannot contain space or it would be ignored, e.g.
\POS\SetupApp.exe is valid but \POS\Setup App.exe would be ignored.

Change Admin Password
It is recommended to change default admin password before deploying PDAto customer sites. To facilitate
changing a number of PDAs with ease, a separate “Admin Password Changer” SDcard utility is provided.
Copy AdminPwdChanger.exe and password.txt to a SD Card folder
Open password.txt and edit entry below:
ENCRYPTION_KEY=KKKKK
OLD_ADMIN_PASSWORD=PPPPPP
NEW_ADMIN_PASSWORD=NNNNN
where KKKK is a key combination of numbers & capital letters. Min
length = 8, Max length = 16
PPPPP is the original password
NNNNN is the new password (Min length=8, Max length=16)
Configuring an autorun.inf in SDCard to runAdminPwdChanger.exe
utility, new password could be deployed to a number of PDAs easily
