User manual

Low battery indicator: If it is enabled, while the power is low, the power LED on the handheld unit flashes

5 times, and the beeper emits 5 beepers for every 10 minutes or 200 scans. In this battery low status,

the power LED flashes 2 times by pulling the scanner trigger.

Enter sleeping mode interval: If it is enabled, the handheld unit will enter sleeping mode while no

operation beyond the time interval defined; the handheld unit will return to normal mode by pulling the

scanner trigger.

Enter transmitting data mode interval: There is no continuous scanning motion time interval of before the

domination handheld unit entering the barcode transmission status. By default when out of range, if

there is barcode data awaiting transmission, the handheld unit will try to transmit data to the cradle after

no scanning motion occurs for 5 seconds. This can avoid conflict between transmission of barcode data

and scanning barcode motion requested by user.

VALID/INVALID/LOCK/UNLOCK protocol：If enabled, the host will validate the data after receiving data

from the connected cradle. The host will send VALID/INVALID/LOCK instruction to the cradle after

validating the data and the cradle will divert the instruction to the associated handheld unit. The

handheld unit will give different audio and visual indication depending on the instruction received from

the cradle.

Note that 1 handheld unit is paired with 1 cradle/base unit to work in this mode is suggested, because

some pauses may be obvious before data validation.

When a LOCK instruction is received, the decoding function of handheld unit is deactivated and will be

reactivated until the receipt of a UNLOCK instruction. The sketch map is shown below:
