Information:

Below are instructions for update U2 firmware. Two options exist:

• Using internet - wireless connection required.
• Offline - using a memory stick or SD card, you will also need to be able to download firmware on another computer to complete offline firmware update.

Update automatically using the Internet

1. Make sure you are connected to the Internet and plugged into AC power. Press "Enter" on "Upgrade U2 Firmware" in the "Utilities" menu.
2. Press "Enter" on "Upgrade: Online". The U2 connects to the HIMS server, and your current software version is compared to the HIMS server version. You are prompted to continue with the upgrade.
3. The U2 begins downloading the upgrade files. If the upgrade fails, you may receive the message, "Internet connection is not available. To try the upgrade again, press "Space-Z" to cancel, and activate "Upgrade U2 Firmware" again. If the connection is successful, the upgrade files are downloaded.
4. After downloading the upgrade files, U2 automatically starts the upgrade process. Please remember you must not touch the U2 until the upgrade is complete as pressing keys, resetting, or unplugging the unit can interrupt the upgrade process, thus resulting in an incomplete installation. When the upgrade is complete, you are returned to the "program" menu, and the unit announces, "File manager".
5. After the upgrade is complete, check the software version by pressing "Space-V" while in the "program" menu.
