User Guide
After establishing a WPAN connection successfully…
1. Once a WPAN connection is established successfully, the scanner will stay active for a specified
period of time (2 minutes by default) for data transmission. Its CPU is running at full speed,
and the LED is flashing blue (On/Off ratio 0.02 s: 3 s).
2. If it is idle within 2 minutes, the scanner will become inactive to save power for the remaining
period of time (the specified value minus 2 minutes). Its CPU is running at low speed, and the
LED is flashing red (On/Off ratio 0.3 s: 2.5 s).
Press the [Trigger] key to wake up the scanner when it becomes inactive, and the scanner will
stay active again.
For BT HID or SPP, there is no transition from full CPU speed to low CPU speed. However,
when connecting with 3610, the scanner will go through the transition in order to save
power.
3. If it is idle and finally stays inactive until the specified time interval for Auto Power Off has
elapsed, the scanner will automatically turn off in order to conserve battery power. You will
hear three short beeps, tone descending from high to low.
Hold down the [Power/Delete] key for about 2 seconds to turn it on.
For BT HID, the scanner will resume connection with the host upon powering on again, as
long as the host application is running. You will hear three short beeps, tone ascending
from low to high. If the scanner fails to resume connection, it will try every 5 seconds to
re-connect to the host unless you have the scanner read the “Reset Connection” barcode.
For BT SPP Slave Mode, the scanner must wait for the host to re-connect.
For BT SPP Master Mode, the scanner will resume connection with the host upon powering
on again, as long as the host application is running. You will hear three short beeps, tone
ascending from low to high. If the scanner fails to resume connection, it will try every 5
seconds to re-connect to the host unless you have the scanner read the “Reset
Connection” or “Restore System Defaults” barcode.
With the use of 3610, the scanner will try re-connecting to 3610 unless you turn off the
scanner.
