n general, devices that communicate using radio frequency, such
as your system , can be sensitive to signal interference and signal
attenuation. This chapter provides tips for optimizing radio-

frequency (RF) communications with your InstaScan and Dura-label.

Topics in this chapter include:

• Signal interference

—

see page 24.

• Signal attenuation
