Configuring to Connect With a Mobile Phone or a Modem 
If you want the CK1 to transfer information through a mobile 
phone connection, use the mobile phone cable (P/N 073851) to 
connect the CK1 to a mobile phone with a PC connect cable.  
Your application must be set up to: 
•  communicate with the mobile phone. 
•  turn on the external 5 Volt in the connection with the CK1.  
•  detect if the CK1 is sending or receiving data through the 
connection and turn off the connection if no data is being 
transferred. Turning off the connection prevents you from 
being charged for phone time when no data is being 
transferred. 
For help creating applications, see Chapter 3, “Developing and 
Using Applications.”  
You also need to subscribe to a data transmission service for your 
mobile phone. For help, contact your mobile phone service 
provider. 
The following procedure explains how to configure the CK1 to 
dial up over either a modem or null modem connection. 
To configure and connect the phone connection 
1  Connect a mobile phone cable that is connected to a mobile 
phone to the CK1 I/O connector, or place the CK1 into a 
modem dock that is connected to a phone jack and power 
outlet. 
2  Log in to the CK1. For help, see the “To log in” procedure 
on page 22. The Setup screen appears.
