DBD-470 Deutsch/Englisch Professor User's Guide

Your DBD-470 is powered by one
CR2032, 3-volt battery. Before using
the device, gently pull the battery
insulation tab to remove it. Use a
paper clip to gently press the RESET
button on the back of the device. See

with more than light pressure may
permanently disable the device. In

tings and information you may have
