Problems and Possible Solutions
Problem Possible Solution
You press the scan
button, but nothing
happens.
The SF61B is powered by a rechargeable lithium-
ion battery
. Make sure the battery is not fully
discharged. Charge the battery then try scanning
again (see Charging the Battery in Chapter 1).
The Status Light blinks
red slowly.
The battery is low. Charge the battery (see
Charging the Battery in Chapter 1).
You press the scan
button, 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 SF61B is configured for the
symbology you are scanning.
• Make sure that the SF61B is at the appropriate
scanning distance and angle from the bar code.
Move the SF61B closer and farther away and
tilt it up and down to find the appropriate
distance and angle.
• Make sure that the SF61B is able to read the
type of bar code you are scanning (1D, 2D).
• Make sure the bar code you are trying to scan is
not poorly printed or not too small. Scan a
known good bar code to make sure that the
SF61B is working properly.
• Clean the scan window if it is dirty.
For more information, see Scanning Bar Codes
in Chapter 1.
You scan a bar code, the
SF61B vibrates and
emits six very fast beeps.
This indicates a transmission error, check that:
• your product is correctly connected to your
host device / application
• your host device / application is able to receive
the data from your scanner
