Usage

For optimal UHF tag read performance and to ensure that human exposure to RF energy does not exceed the FCC and European Union guidelines, always follow the instructions and precautions below:

• Before using the KDC480 UHF reader, the user should carefully read this operation guide and user guide to understand how to use KDC480 UHF reader properly.
• The KDC480 UHF reader should be used by a professional person who fully understands how to operate the KDC480 UHF reader.
• Maintain at least 20cm (about 8 inches) between the KDC480 UHF reader and the body when reading UHF RFID tags.
• Keep the KDC480 UHF antenna facing towards the UHF RFID tag. Do not direct the antenna towards the body when reading UHF RFID tags.
• Exit UHF tag read mode and enter Barcode read mode when finished reading UHF tags.
• Do not wear the KDC480 UHF reader when not using the KDC480 UHF reader.

3.1 Read RFID tag and Barcode with trigger: Trigger mode
In the trigger mode, with the trigger on the pistol grip, you can read barcodes and UHF tags. If you pull trigger once then KDC480/485 reads RFID tag and pull trigger twice very shortly then KDC480/485 reads barcodes.
The following are barcodes to enable/disable Trigger mode.

3.2 Toggling the Read Mode: Barcode mode vs. UHF mode
With the same SCAN button or the trigger on the pistol grip, you can read barcodes (Barcode mode) or UHF tags (UHF mode) depending on the read mode and you can change the mode alternatively.
a) On “Barcode mode”, a barcode can be read by a SCAN button or trigger button.
b) On “UHF mode”, UHF tags can be read by a SCAN button or trigger button.
c) By default, it is a “Barcode mode” and also it is set back to a “barcode mode” after the factory default.
d) There are two ways to change the read mode:

1. Press and hold the UP button for 3 seconds
2. Change from within the application using SDK
   e) When the mode is changed, the KDC will give a series of beeps to confirm the mode change: When you enter UHF Mode: 1 long and 2 short beeps When you enter Barcode Mode: 1 long and 1 short beep
   3.3 Changing the UHF Read Tag Modes: Single, Multiple, or Active
   This mode only works when the device is in UHF mode. Refer to 3.1 to see how to toggle read modes.
   When in UHF Mode, you have the option of scanning in 3 different modes. The modes change in the following order: Active (default) read -> Single read -> Multiple read. The mode can be changed by pressing the DOWN button for 2 seconds.

• Single mode: Only one tag is read every time the scan button is pressed. o 1 short beep will occur when changing mode with Down key.
• Multiple mode: When the Scan button is pressed, reads multiple tags simultaneously for the set time (default 10 seconds). o 2 short beeps will occur when changing mode with Down key. o Time setting can be changed in Settings ->Reading Timeout.
• Active mode: Basic operation status. Simultaneous reading of multiple tags while pressing the scan button (max. 10 minutes) o 3 short beeps will occur when changing mode with Down key.

Alternatively, you can scan the special barcodes (page 6) to change the mode. To change from active mode to another mode, you should disable the active mode first.

In Active Mode, if the SCAN button or Trigger button is pressed more than 10 minutes, the read mode automatically changes from UHF Mode to Barcode Mode to save battery life in the case of the trigger being stuck in the scan position. This option is enabled by default and may be disabled.
If you need to scan with the trigger depressed for more than 10 minutes, you need to disable the Active Read 10 Minute Timeout.
Active Read 10 Minute Timeout
3.4 UHF Tag Counting (Beep Count)
By setting the Count attribute, you can get an estimate on how many tags are read per beep.

• Count = 0: The device only beeps once when you start reading
• Count = 5: Beeps once every 5 tags read. Example: 2 beeps means you read 10 to 14 tags.
• Count = 10: Beeps once every 10 tags read. Example: 2 beeps means you read 20 to 29 tags.
• Count = 20: Beeps once every 20 tags read. Example: 2 beeps means you read 40 to 59 tags.
• Count = 50: Beeps once every 50 tags read Example: 2 beeps means you read 100 to149 tags.

Scan the barcode on below that corresponds with your preference for Tag Counting.

3.5 Phone Charging Option
This option allows the user the option to charge their phone via the extended battery contained inside the pistol grip.

• Enabled (Default): Phone charging from the extended battery is enabled.
