Activate the CDMA Phone
To activate the CDMA phone in your mobile computer, you need to 
contact your wireless carrier and set up an account.
You also need to provide the carrier with the Mobile Equipment Identifier 
(MEID) for the computer. You can find the MEID:
• on a label located in the battery compartment.
• on the outside of the computer shipping box.
The activation process is slightly different for each CDMA carrier. Your 
carrier sales contact and a Honeywell representative can guide you 
through the process.
Make a Phone Call
Once the phone is activated, you can make a phone call.
1 On the Start screen, tap  .
2 Tap the keypad icon to enter the number, and then touch the Call 
button to dial the number.
Answer the Phone
When you receive a phone call, the Incoming Call screen opens, 
showing the caller ID. All incoming calls are recorded in the Call log. If 
you miss a call, you receive a notification.
Make an Emergency Phone Call
You can use the phone to make an emergency phone call, even if the 
SIM card is missing from your UMTS phone or if you do not have a valid 
CDMA account. In either case, the phone shows that you have no 
service. However, if you dial certain emergency numbers (such as 112, 
911, 000, 08, 118, 119, or 999) the call will go through.
Note: For the CDMA phone, settings are permanently stored in the 
WWAN radio after activation. CDMA settings persist through a factory 
data reset.
