1.1.2 AUTO POWER OFF & POWER-SAVING
The scanner will stay active at power-on, which may be followed by a transition from full
CPU speed to low CPU speed (Power-Saving) to auto shutdown (Auto Power Off).
Power-Saving (1~254 min.; 0= Disable): By default, it is set to stand by at full-speed
for 2 minutes before it enters low-speed mode. If this feature is not desired, set it to
0.
Auto Power Off (1~254 min.; 0= Disable): By default, it is set to automatically shut
down after 10 minutes. If this feature is not desired, set it to 0.
Before establishing a WPAN connection successfully...
1. The scanner will stay active for a specified period of time (2 minutes by default) for the
following scenarios. Its CPU is running at full speed, and the LED is flashing blue (On/Off ratio
0.5 s: 0.5 s).
(a) waiting for a connection request from the host (BT SPP Slave Mode)
(b) trying to connect to the host (BT HID or BT SPP Master Mode)
(c) trying to connect to the cradle
2. If it fails to connect 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 to wake up the scanner when it becomes inactive, and the scanner will stay
active again.
3. If it fails to connect again and again, and finally stays inactive until the specified time interval
has elapsed, the scanner will automatically turn off in order to conserve battery power.
Hold down the trigger for about 2 seconds to turn it on. For scenarios (a) and (b) in step 1, on
your computer you will have to search for the scanner again.
After establishing a WPAN connection successfully...
Once a WPAN connection is established successfully, the LED is flashing blue (On/Off ratio 0.02 s:
3 s). If the scanner is idle during the specified time interval for Auto Power Off, it will automatically
turn off when the time is up. You will hear three short beeps, tone descending from high to low.
For BT HID or SPP, there is no transition from full CPU speed to low CPU speed. However, when
connecting with the cradle, the scanner will go through the transition in order to save power.
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" label.
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" label.
When using the cradle, the scanner will try re-connecting to the cradle unless you turn off the
scanner.
