How do I change the hot swappable batteries on the Venus mobile medical cart or other devices?

Most importantly, never replace both Onyx batteries simultaneously as this will turn off your computer, potentially loosing critical medical information. Always replace your battery one at a time and place them on the battery charger as soon as possible.

Watch this short video to see how a Venus battery can be changed in under 20 seconds.

How do I clean my Onyx medical grade unit?

Watch our short video to find out about how to best clean your Onyx medical grade computer.


Make sure you always use an antibacterial wipe to clean your medical grade unit.

Start by wiping from the front of the screen in a top to bottom motion and then finish across the bottom. This method minimises the amount of streaking on the screen. Once finished, dispose of this wipe.

With a new anti-bacterial wipe clean down the back surface in whatever way practical and dispose of the wipe. Do not use the same wipe for the front and back of the medical computer unit as the dirt from the front will be transferred onto the back of the device.

What does a cable-less medical-grade computer mean?

It means that the computer does not need to run off wall power, like several of our Onyx range, rather it is usually powered by an inbuilt battery or UPS system. This is particularly useful in the medical and health care industry as it minimises trip hazards, increases the amount of time the device can be continually used and reduces the need to buy additional computer carts whilst the cable carts are being charged.

Overall a cable-less medical grade mobile computer improves the nursing workflow.
