2.Click OK to launch the firmware update utility and update the firmware in your card. The software installation begins. This process takes approximately five minutes. You may stop the installation at any time by clicking Cancel.

Caution: Do not remove the Merlin S720 from your computer's PC Card slot until the installation process is complete. Failure to complete the process may result in serious errors.

3.Once the firmware has been successfully downloaded, a confirmation screen appears. Click OK to return to the Sprint PCS Connection Manager main user interface.

4.When the firmware update is completed, it will reset the card. Please wait a few minutes to initialize the card from the Sprint PCS network. If the card has not been activated, it will automatically launch the Sprint PCS Vision Activation Wizard.
