2130060 Rev 1.1 Page 5 2. System Overview The Sierra Wireless AirPath 300 is a CDPD radio modem, in the form of a Springboard™module, that you insert in the Springboard expansion slot of a Visor, Visor Deluxe, Prism, Platinum, or Edge handheld device. The AirPath 300 keeps you connected to the wireless network. You can receive and send email, browse the Internet, and use other applications wirelessly. The AirPath 300 consists of a CDPD radio modem, a rechargeable battery, and embedded firmware. The battery is not user-replaceable. 2.1. Required Hardware and Software To use your AirPath 300, you will need: • A HandspringVisor, Visor Deluxe, Prism, Platinum, or Edge handheld computer • An account with a CDPD network service provider in your area

System Overview AirPath 300 for Visor User Guide Page 6 2130060 Rev 1.1

Getting Started AirPath 300 for Visor User Guide Page 8 2130060 Rev 1.1 is sufficient to provide a trickle charge to the AirPath module battery but is not enough to simultaneously power the radio/modem for normal use. To use the AirPath module while trickle charging the handheld, the AirPath 300 DC adapter must also be used. Handheld devices without their own rechargeable battery may also be able to use the Travel Charger to deliver power to the AirPath module. Not taking power to charge a handheld battery, these models can provide sufficient power to support normal use of the AirPath 300 while trickle charging. If you are unsure of the capability of your particular handheld you should always use the AirPath DC adapter to charge the module. 3.2. Attaching the Antenna Attach the antenna to the connector in the top right corner of the AirPath 300 (above the LEDs). The antenna simply presses into place. The antenna should bend easily at the hinge. Do not forcefully bend the antenna. 3.2.1. Recommended Antenna Position Due to the radio frequency interference inherent in all electronic computing devices, the strength of the signal can be affected by the orientation of the antenna. For best results, the antenna should be aligned with the elbow hinge rotated toward the back of the handheld (away from the screen) and the antenna pointing upward, as shown.

AirPath 300 for Visor User Guide Getting Started 2130060 Rev 1.1 Page 9 3.3. Inserting the AirPath 300 You do not have to turn the handheld device off before you insert the AirPath 300. Insert the AirPath 300 into the Springboard expansion slot of your handheld device until the connectors are secure. Do not use excessive force, since this may damage the connector pins. If the handheld device was off, it will automatically turn on. The Service Connection Progress screen opens to indicate the handheld is connecting with the AirPath 300 module. The applications for browsing the Web and checking your email are then automatically loaded from the AirPath 300 onto the handheld device1. 3.3.1. Turning the Unit On and Off The AirPath 300 does not have an on/off switch. The AirPath 300 automatically turns on when: • You insert it into the handheld device (if the handheld is off, it will turn on automatically) • You start Watcher or another application that requires Internet or email access • You insert the DC adapter, or in some cases, the handheld’s Travel Charger. See section 3.1.1. The AirPath 300 automatically turns off when: • You tap the Shutdown button in the Watcher application to deregister from the network and turn off the AirPath module CAUTION Removing the AirPath module without first using the Shutdown option in Watcher is strongly discouraged. This can cause disruption because the AirPath adapter will not have deregistered from the network. 1 The applications are removed from the handheld device when you remove the AirPath 300.

Getting Started AirPath 300 for Visor User Guide Page 10 2130060 Rev 1.1 • You exit your web browser or e-mail application (power off is delayed by a duration you configure in the Network Preferences of the handheld) • You turn off the handheld device (the AirPath 300 turns off after approximately 10 seconds) • You remove the AirPath module from the handheld device (the AirPath 300 turns off after approximately 10 seconds) NOTE The handheld will reset when the AirPath 300 module is removed. To preserve battery life, remove the AirPath adapter from the handheld if you will not need network access for an extended period. 3.4. Configuring the AirPath 300 The first time you insert the AirPath 300 into your handheld, the AirPath Configuration program will automatically launch. This program controls the modem’s connection to the Wireless IP (CDPD) network. 1. Contact the Wireless IP network provider you wish to use, and state that you wish to activate an account for your CDPD modem. The Wireless IP service provider will ask you for the EID of the modem. The EID is displayed in the top portion of the AirPath Configuration screen, and also on the label of the AirPath 300 module, in the format 00-A0-xx-xx-xx-xx. The service provider will give you values for an NEI (IP address), DNS, SPNI, and side preference. Write this information down. (After you have finished configuring your AirPath 300, you should keep this information in a safe yet accessible place). 2. In the AirPath Configuration screen, enter the NEI, DNS, SPNI, and side preference. The SPNI entry can have zero, one, or more SPNI values, separated by commas. The AirPath 300 will accept service only from a provider on the list. If the

The Watcher screen also displays a Status message. See Table 4-3 below for descriptions. Table 4-3: Interpreting the “Status” Message “Status” message How to interpret / suggestions Awaiting confirmation This step is the equivalent of "logging-on" to a network. The CDPD network checks the AirPath 300's credentials to ensure the device is authorized for network service. Establishing data link This is the first step in establishing a connection on the CDPD network. It involves “handshaking”, where both ends of the data link agree on the protocols to be used. Initializing encryption This is the second step in establishing a connection on the CDPD network. All network traffic is encrypted for security reasons. This step involves the transmission of an encryption key that is used by both ends of the data link to encrypt and decipher the data. Registered The registration was successful. Your device is ready to receive and send email, browse the Internet, and use other applications wirelessly. Inter-area transfer CDPD service areas are divided into geographic zones called "cells". Each cell has its own cellular base station. This message occurs when travelling from one cell to another and it indicates that you are being "handed off" to a different cell.
