Firmware Upgrade Guide

To download the latest firmware :

Step 1. Be ready with a USB flash drive or memory stick with free space of 150 Mbytes or more.
Step 2. Plug in the USB flash drive to a USB port of the computer.
Step 3. Click the latest firmware zip file on the website and save it to the root directory of the USB flash drive. You can also download it directly to your hard drive.
Step 4. Unzip the downloaded file into the root directory. Ensure that there are two files extracted in the root directory of the USB flash drive: one firmware file (*.fw) and one firmware release note (*.pdf).

To install new firmware :

Step 1. Take the flash drive out from your computer, and then plug it into the USB Host port on the top side of your device.
Step 2. Power your instrument via the AC-DC adapter.
Step 3. Press the SYSTEM hot key.
Step 4. Select More (1/2) > Upgrade. The file manager window appears.
Step 5. Highlight the new firmware file (.fw) that you have saved in the root directory of your USB flash drive using the rotary knob. You can also touch on the screen.
Step 6. Press the Select soft key. The confirmation dialog box appears 
Step 7. Do one of the following:
- Select Cancel to cancel the process and exit without upgrading.
- Select OK to continue upgrading. The instrument starts to install the firmware and the upgrade status pane appears 
Step 8. At the completion of the installation, the instrument reboots itself automatically.

WARNING:

- Do NOT remove the USB flash drive from the instrument while installing the firmware. In most cases, the installation will be done within 30 minutes or so although it may take longer than that depending on the number of files to be reconfigured.

About Device Firmware:

Applying a newer firmware version than the one already installed on your unit can bring various enhancements, include workarounds for diverse problems encountered by the device, and improve or add newly developed features.

On the other hand, downgrading the firmware version can recover the device’s functionality in the event of a software update either turning up faulty or causing the unit’s overall performance to drop. However, bear in mind that applying an older firmware isn’t recommended and might not always be possible.

When it comes to the update steps, due to the large variety of devices and numerous ways for installing a new firmware, it is recommended that you carefully read and understand the upgrade steps, and consider applying a different firmware only when you have familiarized yourself with the update method.

As the installation process is most of the times quite risky, this step should be taken by users that have the ability to successfully complete the update; regular users may initiate it at their own risk. Moreover, it’s best that this task be performed in a steady power environment such as the one ensured by a UPS unit.

Therefore, if you consider applying this release, hit the download button, take into account all the aforementioned aspects, and update the device’s firmware. Also make sure you constantly check with our website to ensure that you don’t miss a single new release.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
