1.1.2 AUTO POWER OFF
Specify the time interval (1~254 min.; 0= Disable) for the scanner to automatically turn
off in the following circumstances. By default, it is set to 10 minutes. If this feature is not
desired, set it to 0.
Auto Power Off before establishing a WPAN connection successfully...
1. The scanner will stay active for 2 minutes 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)
(b) trying to connect to the host (BT HID)
(c) trying to connect to 3656
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 for 2 minutes 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.
Auto Power Off 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 3656, 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, the scanner must wait for the host to re-connect.
With the use of 3656, the scanner will try re-connecting to 3656 unless you turn off the
scanner.
1) Read the label above to specify the time interval before the scanner automatically
turns off.
2) Read the “Decimal Value
” label on page 187. For example, read “1” and “5” for the
scanner to automatically turn off after being idle for 15 minutes.
3) Read the “Validate” label on the same page to complete this setting.
