Installation Guide:
STEP 1: Back up Data on the Device
If you have any data on the SoMo 655, please back it up to an external location before you run the
update.
STEP 2: Transfer the File to the Device
Move the SOMO655 folder containing the ROM image files to the SoMo 655 with a microSD or CF
memory card that is formatted in FAT12 or FAT16. If you downloaded the software, extract the ZIP file
and save the SOMO655folder to your computer. Make sure your memory card has at least 70 MB of free
space.
1. On your PC, use My Computer or Windows Explorer to locate the
SOMO655 folder, which contains the upgrade files.
2. Copy the SOMO655 folder to the root of your memory card.
3. Insert the memory card into the device.
Most higher-capacity cards are formatted by default in FAT32, which is not supported. Do NOT
use an SDHC card as they are not supported in Windows Embedded Handheld.
IMPORTANT: Copy the SOMO655 folder to the root of the memory card! DO NOT change the
name of the folder!
Good Example: F:/SOMO655 Bad Example: F:/Socket/SOMO655
Bad Example: F:/SoMo_655

Socket Splash
Today
The SoMo 655 will begin to download and update the ROM image.
After the installation reports, “Update completed!” the Socket splash screen will appear for about 30
seconds then disappear.
The Windows Embedded Handheld splash screen will appear for about 30 seconds.
The Windows Welcome wizard will prompt you to set up Windows Mobile. Follow the instructions on
your screen.
After setting up Windows Embedded Handheld, the Today screen will appear, and the SoMo 655 will be
ready to use.
STEP 4: Verify the Upgrade Installation
Prior to going the final step you may want to ensure that the upgrade has completed successfully.
1. On the SoMo, tap the Windows icon | Settings | System.
2. Tap on System Info.
3. Under OS Version, check the ROM version. It should be 1.00.00 SP1 (build 9351)
.

STEP 5: Perform a Clean Boot
A clean boot reverts the device to its factory default settings (or the latest service pack ROM update).
All installed programs, data and registry settings will be cleared, except those saved in the SoMo File
Store. A clean boot also drives the processor with a hardware reset, thus clearing all system states,
including the date and time.
To perform a clean boot:
1. Provide power to the SoMo using the AC adapter.
2. Press and hold three buttons, the Start Control button and F2 Configurable button (buttons closest to
the screen), and the Left Application button.
3. While holding the three buttons, use the tip of your stylus to lightly press and release the Reset button
on the back of your SoMo 655.
It is recommended that you hold the SoMo 655 upside-down in your left hand. Press and hold the
Start Control button and F2 Configurable button (buttons closest to the screen) with your left index and
middle finger and the Left Application Button with your left thumb. Hold the stylus in your right hand
to press and release the reset button.
CAUTION: A CLEAN BOOT IS MORE POWERFUL THAN A WARM OR COLD BOOT. IT WILL
DELETE ALL USER APPLICATION FILES AND FOLDERS. WHEN YOU PERFORM A CLEAN BOOT,
FORMATS, PREFERENCES AND OTHER SETTINGS INCLUDING DATE AND TIME ARE RESTORED
TO THEIR FACTORY DEFAULTS. ALL DATA, RECORDS AND ENTRIES, EXCEPT THOSE STORED IN
ROM OR THE FILE STORE WILL BE ERASED.
If you set a security password on the SoMo 655 and forget it, a clean boot will remove the
password setting.

Configure Mode Switch
The mode switch helps you extend the battery life. With Profile A set as the Active profile, the battery life can be
optimized for performance during activity. With Profile B as the Background profile, the battery life can be
optimized to save battery power during inactivity.
1. In the list of Getting Started wizards, tap Configure Mode Switch.
2. Tap on the link in the wizard to access the Change Mode switch settings.
3. Use the utility to configure your settings.
Step 1
Select the Enable the Mode Switch checkbox.
•To use the factory settings as the Active profile, tap the Restore the same
settings I had before radio button. Then, tap on Profile B and skip to Step 3.
•To customize your settings, select the Use the settings specified in profile A
radio button. Then, tap on the Profile A tab.
You may configure two profiles to suit your purposes. Typically, Profile A is the
Active profile (optimized for performance), and Profile B is the Background profile
(saves energy). However, you may configure it any way you like. You may select a
particular program in each of the profiles to launch when the mode switch is
employed. In both profiles, the WiFi remains connected resulting in an immediate
and smooth transition from Background to Active.
NOTE: When the Mode Switch is activated and the behavior is set to Restore the same settings I had before, the
Bluetooth radio state will not be restored to Discoverable when expected. Instead, the state is restored to ON,
non-discoverable.
If the option Use the settings specified in profile A is used, the utility will set the Bluetooth radio to Discoverable if
so configured. Profile B also correctly sets the Bluetooth radio state.

12
Step 2
When configuring Profile A, consider this the Active profile. Set your SoMo at
optimal performance speed and use this profile for getting work done.
•Tap on each dropdown menu to configure settings. (See table below for
settings information.)
•Tap on Profile B tab.
Step 3
When configuring Profile B, consider this the Background profile. Set your SoMo to
save energy for when it is not in use, but you don’t want to turn it off.
•Tap on each dropdown menu to configure settings. (See table below for
settings information.)
•Tap on OK.
Step 4
•Tap on ok.
Changes will be applied next time you move the Mode Switch.

The SoMo 655 can be used in any of 13 languages. Use the Change Language wizard to choose a different
language for your operating system.
WARNING: THIS UTILITY WILL ERASE ALL USER DATA FROM THE SOMO. It is
recommended you change the language before you begin using your SoMo.
In the Getting Started wizard, tap on Change Language.

WARNING: To change the language again (after having changed it once) will
require saving the language files on a microSD card, or downloading them
from http://support.socketmobile.com.

card. Or, the language files are available for free to registered users. Log in to
get them at: http://support.socketmobile.com.

By default, the SoMo has Microsoft Wireless Zero Configuration installed. Enhanced Wi-Fi Companion (e-WFC) is
also pre-loaded but must be manually installed.
Enhanced Wi-Fi Companion offers many security benefits including advanced authentication (including PEAP-GTC,
EAP-TTLS, LEAP, EAP-FAST); WMM including transmit power control and CCKM; Cisco CCX 4.0 compatibility; and a
Socket profile editor with advanced functionality.
