If it becomes necessary to adjust the nominal voltage for use in another zone, the power transformer and the power fuse must both be replaced with original parts from Cyrus to be the correct type for the new zone AC fuse There are no user-replaceable fuses fitted to the DVD6.
Page 7 CYRUS DVD6 SMD COMPONENT REPLACEMENT Handling SMD resistors and capacitors are widely used in the Cyrus range of products. When handling SMD components, certain precautions should be observed- Handling SMD resistors and capacitors Always store SMD components in their original packaging or in a cool dry environment.

Page 12 CYRUS DVD6 TECHNICAL DESCRIPTION Disc reading/decoder module A disc-reading module is at the heart of the DVD6. The module includes a twin laser mechanism and a decoder PCB. The decoder PCB performs a number of functions, decoding video and audio data from the DVD and includes the firmware for disc navigation, on-screen menus etc.

In this case the plug-in DAC PCB is removed, allowing the Q7 module to be plugged into CON106 and CON107. Digital audio signals are then routed into the Q7 through CON106 and analogue audio out through CON107.
Page 14 As part of the DVD Video system specification, each player is set for operation in one specific region of the world. Each DVD6 is marked with its region on the rear panel and the carton. In accordance with the DVD specification, the DVD6 will only play discs intended for the region in which it is sold.
Page 15 Power for the video buffers is derived from the ±12V analogue supplies. Using fixed voltage regulators to generate the ±8V supplies, these are further regulated to ±5V using simple transistor regulators. © Cyrus Electronics Ltd Dec 2003 Cyrus DVD6 Service Manual Issue 1...
Page 16 No response to MC-Bus The DVD 6 will not auto power via the MC-Bus when selecting CD as the source from a Cyrus pre- amp or integrated amp. This is correct - it will only respond when AV is selected and must be connected to the AV input if using the MC-Bus.

If it becomes necessary to install a later version of software, contact Cyrus UK for availability of the Flash-Programming Interface box and software. This is supplied with full instructions to set the programming software up on a PC and load the DVD6 software for installation into the player memory.
Page 20 MC-Bus is a system which provides communication between the control systems of a number of Cyrus products. The communication takes the form of a serial data stream which is sent from a 'master' product and received and repeated by 'slave' products. The data is thus passed from one product to another around a loop.
