4.10 Wakeup Nulls

The KDC sends three leading Null bytes to wake up connected Bluetooth device. This feature can be
disabled if connected Bluetooth device doesn't require additional bytes to wake up.

4.11 Autolock Time

iPhone/iPad/iPod touch loses incoming Bluetooth data in sleep mode. Users can set KDC Autolock time to the
same Autolock time of your iPhone/iPad/iPod touch to use automatic wakeup feature in HID mode to prevent
data loss. There would be a one second delay of barcode transmission if Autolock time is set to more than one
minute and the barcode scan interval is larger than auto lock time. The autolock time would be set as 0, 1, 2, 3,
4, 5, 10, 15 minutes. 0 means iPhone/iPad/iPod touch never enters sleep mode.

4.12 HID Keyboard

User can select international keyboard – English, German, French, Spanish and Italian.

4.13 HID Initial and Inter-Character Delay

Certain application can't process HID input fast enough and lose some characters during transmission. Users
would increase initial and inter-character delay to prevent data lose during HID transmission
