Avery Dennison 9850 RFID Multi-Protocol - Manual (Page 45)

Single Protocol Encoding A-3
Attenuation
Reduces the strength of the RF Field emitted by the printer’s antenna.
The higher the value, the greater the reduction in the power of the RF
Field.
If the attenuation is set too low (too much power), the tag being
programmed may become non-functional and/or the data in the adjacent
RFID tags may be corrupted. If the attenuation is set too high (too little
power), you may not be able to program the RFID tag in the RF Field.
CAUTION
Use extreme caution when decreasing the attenuation
(increasing power) because the RFID tags may
become non-functional!
To change the setting, from the Main Menu, select Setup, then RFID.
Then follow these steps.
1. Press Å or Æ until you see
RFID
Å
Attenuation Æ
2. Press Enter/Pause. The current setting is displayed, for example:
