Problem Possible Solution
You pull the trigger, but
nothing happens.
The SG20B is powered by a rechargeable lithium-
ion battery
. Make sure the battery is not fully
discharged.
To recharge your SG20B scanner, dock it in a
properly powered SG20B Charge Bluetooth Base
or SG20 Bluetooth Base Station (see “SG20
Bluetooth Base Station Recommended
Connections” on page 23).
You pull the trigger, the
red scanning beam (1D)
or laser framing (2D)
turns on, but you
cannot successfully scan
a bar code.
Try these possible solutions:
• Make sure that the SG20B is configured for the
symbology you are scanning.
• Make sure that the SG20B is at the appropriate
scanning distance from the bar code. Move the
SG20B closer and farther away to find the
appropriate distance.
• Make sure that the SG20B is configured for the
type (1D, 2D) of bar code you are scanning.
• Make sure the bar code you are trying to scan is
not poorly printed or too small. Scan a known
good bar code to make sure that the SG20B is
working properly.
For more information, see “Scan Bar Codes” on
page 7.
You scan a bar code and
the status light turns
on, but the SG20B does
not beep.
The beep duration, volume, frequency, and
number may be configured so the SG20B does not
beep. To reset the SG20B, scan this bar code:
