Precautions

The CC unit incorporates a CMOS IC. Particular care is to be taken about its damage static electricity causes when you make switch settings.

Lithium battery is used for a memory backup battery BAT-1, which maintains the important data stored in a memory during power outage. A life span of the lithium battery largely varies depending on ambient temperature and a space of time that the exchange was used. To be on a safe side, therefore, we suggest that the battery be replaced every 3 years. Be sure to set up No. 24 programming again after its replacement.
