Effect Of Nearby Metal Object Onto Idrw Head - Omron V700-HMD13 series User Manual

Section 6
Performance Data Based on Operating Conditions (information only)
The maximum effective communication distance of an IDRW head varies depending on the operating
conditions (presence/absence of a nearby metal object, number of the IDRW heads, etc.). This section
describes the effect of varying operating conditions on the effective communication distance. Before operating
the IDRW heads, study the information in this section. The values mentioned here are given only as a
guideline.
