1660 Barcode Scanner
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 1660 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)
(b) trying to connect to the host (BT HID)
(c) trying to connect to 3610
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] key 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 [Power/Delete] key 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 3610, 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
