Safety Check After Servicing

After servicing, make measurements of leakage-current or resistance in order to determine that exposed parts are acceptably insulated from the supply circuit. The leakage-current measurement should be done between accessible metal parts (such as chassis, ground terminal, microphone jacks, signal input output connectors, etc.) and the earth ground through a resistor of 1500 ohms paralleled with a 0.15 iF capacitor, under the unit's normal working conditions. The leakage-current should be less...

Safety Instructions Informations

Parts identified by the symbol are critical for safety. Replace them only with the parts number specified. 2. In addition to safety, other parts and assemblies are specified for conformance with such regulations as those applying to spurious radiation. These must also be replaced only with the specified replacements. Examples Noise blocking capacitors, noise blocking filters, etc. 3. Use specified internal wiring. Note especially 1) Wires covered with PVC tubing 4. Use specified insulating...

OS Update Procedure

The OS update can be made from the PC via the USB port. You must have the OS loader software for MPC4000 besides the OS .bin file. The OS loader software includes the OS Loader.exe file, USB driver.inf file, and USB Driver.sys file. 1. Install USB Driver to your PC After all files are un-Zipped, place the USB Driver.inf and USB Driver.sys files into the same folder, e.g. Driver. Boot up the PC and MPC4000 complete and then connect the sampler to the PC using the USB cable. This prompts that the...
