2 The Display Clock on Models CVA 4062 and CVA 4066 May
Change Time Unexpectedly
On some CVA coffee systems, the display clock may change suddenly back to 12:00
without any warning or user intervention. This applies specifically to the CVA 4062 and
CVA 4066 models. Other functions of the coffee system are not affected.
This is a software issue. To resolve it please apply the firmware update provided in the
latest version of the MDU software (V4.5 11.19.2009)
If you experience any difficulty when connecting to the CVA with the optical interface,
remember you may need to turn the machine off for a few seconds using the main
power switch.
3 CVA & French Roast Coffee
In many cases, customers who use Starbucks or Costco French Roast coffee are
experiencing frequent episodes of brew unit blockages. We do not recommend using
this style of coffee at this time. The preferred method for brewing French Roast is to
use a ‘French Press’. Our manufacturing engineers are looking into this situation and if
there are any changes, we will announce it here. In the meantime, you can quote this
passage from the Starbucks UK Website:

Brewing French Roast
The best brewing method for French Roast is the coffee press (cafetiere).
