OBID
Use caution when the maximum value of the signal amplitude is reached at the minimum or maxi-
mum position of the trim capacitor (Fig. 3.4.3-3). This usually means the antenna is too severely
detuned by the surroundings and can no longer be fully compensated by the trim capacitor.
After the antenna has bee tuned, check it again for maximum range and any communication gaps.
NOTE:
• Notwithstanding the possibility of retuning the antenna as described here, the distance
FEIG ELECTRONIC GmbH
between the reader and the surrounding metal surfaces must be at least 3 cm. Note that
even other circuit boards may act like metal objects depending on how much copper
they contain.
