6-1-2 Precautions

•Do not attempt to use the CPM1-EMU01-V1 for any applications other than those described here. Doing so may result in malfunction.

•Do not attempt to upload or download data between different types of PC. Do- ing so may result in malfunction.

•Do not download when the PC is in RUN or MONITOR mode. If downloading is performed when the PC is running, it will automatically switch to PROGRAM mode and operation will stop.

•Do not attempt to disassemble, repair, or modify the CPM1-EMU01-V1. Any attempt to do so may result in malfunction, fire, or electric shock.

•After downloading has been completed, be sure to confirm the user program, data, and expansion instruction information. Not doing so may result in faulty operation.

•Before touching the EEPROM or the CPM1-EMU01-V1, first touch a grounded metallic object to discharge any static build-up. Not doing so may result in mal- function or damage.
