Maintenance

Aside from normal care in handling and use, your PC4 requires no regular maintenance.
Clean with a soft dry cloth. Never use abrasives or solvents as they may damage the unit's
paint, markings, and display screen. There are no batteries inside to replace. Instead of
volatile SRAM used in most other instruments, your PC4 uses nonvolatile Flash Memory for
storage, which retains information without power.
