Servicing / Updates
There are no controls, adjustments or other elements inside the case that have to be
operated by the user.
In case of an firmware update the case has to be opened to replace the main processor by
the new version. This service has to be carried out normally by the representative or dealer
where the device has been purchased. The service is offered by the manufacturer (Doepfer,
Germany) or an authorized dealer or service company too. Please look at the web site
www.doepfer.com for a list of all authorized companies.
Any firmware update is not free of charge. The costs for material, working time and shipment
is charged to the customer.
You may even carry out firmware updates yourself at your own risk. In this case the warranty
is lost if a mistake is made during the firmware update.
Pay attention that cases that are damaged while the device has been opened/closed (e.g.
scratched surface, damaged screws) cannot be taken back and the warranty is void.
The device d3c uses a rechargeable battery (accumulator) for memory backup of preset
data. These electronic parts have a limited lifespan and have to be inspected at least every
two years. This should be carried out by qualified personnel only as technical knowledge and
soldering experience is necessary. If you are able to carry out the inspection and the
possible replacement yourself this is the checking/replacement procedure:
• Disconnect the device completely from mains voltage (i.e. remove the mains cable,
turning the device off with a mains switch is not sufficient !)
• Open the case and find out the position of the battery (this is a black or blue cylindric
electronic part with about 15 mm diameter and 15 mm length, the target voltage "3.6V" is
printed on the part).
• Optical inspection: check if the battery is still sealed and has no leakage.
• Electrical inspection: measure the battery voltage with a suitable instrument (e.g. digital
multimeter in voltage mode). The voltage has to be within 10% of the target voltage
(3.6V), i.e. between ~ 3.2V and ~ 3.9V.
• If the optical or electrical inspection indicates any fault the battery has to be replaced by
the same type (i.e. 3.6V rechargeable battery / accumulator with the same dimension).
Suitable batteries are available in electronic stores or from your local Doepfer
representative as spare part.
• If the battery is defective the old one has to be removed (desoldered) and the new one
put in (soldered).
• muss der Akkumulator ausgewechselt werden. Der Akkumulator ist im Elektronik-
Fachhandel erhältlich oder kann von uns oder einer unserer Vertretungen als Ersatzteil
bezogen werden.
• It is not allowed to put the old battery to the normal garbage. Please forward the old
battery for recycling to a suitable receiving office.
