Maintenance
Scanners make an electrical connection to the phone through the
electrical socket at the bottom of the phone. The electrical signals are
very small and require a clean and positive physical connection.
Scanners and Phones that have been in-service often develop contaminated contacts that
will need cleaning before the scanner can be attached.
If the phone screen does not display "Device Attached" when attaching
the scanner, and/or the scan beam does not come out, or the beam comes
out but the phone software does not receive a scan, the problem can
often be resolved with these routine maintenance procedures:
- Turn the phone completely off and detach the scanner.
- Detaching i355/365 SP5 scanners: Push up from the bottom to
remove both the phone and the scanner plug, taking care to not push on
or touch the scan window.
- Ensure that the phone battery is fully charged.
- If you have an SP3
scanner, replace its batteries with brand-new AAA alkaline
batteries.
(The mismatched batteries rolling
around in your "junk" drawer are not brand-new... :-)
- Carefully clean the scan window with an eyeglass lens tissue or a
"microfiber" lens cloth. Do not use a paper towel or
any other paper product not designed for lenses, as these will scratch the lens.
Do not use any kind of solvent other than a single drop of water on
the cloth.
- There is a row of very small gold plated pins at the scanner end
that attaches to the phone. The pins are spring-loaded, and should be
"limbered" and cleaned so that they will make good contact: Carefully push down
on the pins using a new and clean pencil eraser tip. Push
down on the pins about a dozen times each. Brush the pins carefully
and lightly with a clean, dry toothbrush, which you are prepared
to throw away after use. (It can be an old toothbrush, as long as it
is clean and dry.)
- Clean the contacts at the bottom of the phone using the
toothbrush. You can be quite aggressive doing this, as the phone
contacts are not that delicate. A single drop of rubbing alcohol
on the brush can help to dissolve gum or other contaminants.
Brush until the phone contacts are bright and shiny.
- There is a thin plastic rib between each contact on the phone.
These ribs can sometimes be damaged, and bent. If you are careful, you
may be able to straighten out a bent-over rib using a pen knife.
- Reattach the scanner several times to ensure that
it is well seated and that the pins are making a good contact.
- Attaching i355/365 SP5 scanners: It is possible to have the
scanner and phone in the case, yet still not have them fully
connected. To attach, push the phone firmly down into the
scanner plug, then push the phone and scanner into the leather case.
It is a tight fit. Stand the case on end on a table top, and
make a final firm push of the phone down into the scanner plug, then
firmly stretch and reattach the strap over the top of the phone.
- Turn the phone on, and try the scanner again.
- Occasionally, the internal scan engine will need to be "rebooted"
back to its factory settings. This is done by scanning in a special
command bar code that is unique to each scanner model. After
scanning the code, the phone may report a scan error, disregard, and
turn the phone completely off and then on again to complete the reboot
process.
- If your scanner now attaches correctly and emits a beam, but the
bar code numbers do not get displayed on the phone, the problem can be
related to how your software program is configured. Please contact
your software vendor for further instructions on how to configure
their software.
- Tethered system (SP3, RMS
and Lightning) users may benefit from a
simple modification to strengthen the
Falcon phone plug connection.
