To complete the software update, connect the handheld remote to the PC using the USB cable. If the device has been updated previously, the required Optimus updating software application should already be on the PC. Open Optimus and follow the prompts to update the device

If this is the first time updating the device, it will be necessary to download the Optimus updating software application. To download, go to the E-XTEQ website at and select the Download option on the top menu bar. Once accessed, click Download Optimus and follow the prompts to install the Optimus updating software. After installation, open Optimus and follow the prompts to update the device.

When dealerships receive the new DCBS unit, it is critical that the Optimus software, which is included with the DCBS, be downloaded. The Optimus program is used to store all testing records that are performed at the dealership. Additionally, all DCBS software updates that are released to keep the DCBS operating with the latest vehicle information and product enhancements will only be delivered to the handheld diagnostic remote through the Optimus program. Any new software availability prompts will be displayed on the handheld remote.
