period of time (2 minutes by default) for data transmission. The CPU runs at full speed, and
the LED blinks blue (On/Off ratio 0.02 s: 3 s).
2. If the scanner stays idle for 2 minutes (default), it will then turn inactive to save power for the
remaining period of time (the specified “Auto Power Off” value minus 2 minutes). The CPU
runs at low speed, and the LED is blinking red (On/Off ratio 0.3 s: 2.5 s).
Pull the trigger to wake up the scanner when it becomes inactive, then the scanner will stay
active again.
For BT HID or SPP, the scanner automatically shuts down after the configured “Auto Power
Off” time without the transition from full CPU speed to low CPU speed. However, when
connecting with 3656, the scanner will go through the transition in order to save power.
3. If the scanner first becomes idle and finally stays inactive until the specified Auto Power Off
time is up, the scanner will automatically turn off in order to conserve battery power. You will
hear three short beeps, tone descending from high to low.
Pull down the trigger for about 2 seconds to turn it on again.
For BT HID, the scanner resumes the 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 upon the resumption. If the scanner fails to resume the 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 waits for the host to re-connect.
For BT SPP Master Mode, the scanner resumes the 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 upon resumption. If the scanner fails to resume
the 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 3656, the scanner tries to re-connect 3656 unless you turn off the
scanner.
