Chapter 3 — Troubleshooting and Maintaining the SF51
SF51 Cordless Scanner User’s Guide 29
When you reset the SF51:
• The SF51 tries to reestablish a Bluetooth connection with the
host device if the SF51 initiated the Bluetooth connection.
• The SF51 turns on and enters a discoverable state if the host
device initiated the Bluetooth connection. You need to
reestablish the Bluetooth connection from the host device.
Cleaning the SF51
To keep the SF51 in good working order, you may need to
clean the scanner window. Clean the scanner window as often
as needed for the environment in which you are using the SF51.
To clean the scanner window, you can use soapy water, a
solution of ammonia and water, or isopropyl alcohol.
Opening the SF51 will void the warranty and may
cause damage to the internal components.
Attention: Le fait d’ouvrir le SF51 annule la garantie
et peut endommager les pièces internes.
To clean the scanner window
1 Dip a clean towel or rag in soapy water, ammonia and water
solution, or isopropyl alcohol and wring out the excess. Wipe
the scanner window. Do not allow any abrasive material to
touch the window.
2 Wipe dry with a lint-free cloth.
