2. Press the recessed scan switch and lightly place the wand tip on the paper.
The tip should be placed about 1 cm (approx. 0.4 in.) from the first bar in the
row.
3. Scan the bar code at a rapid and uniform speed. (Avoid the tendency of many
new users to scan too slowly, which can prevent the wand from processing
the bar code.)
4. Keep the wand tip in continuous contact with the paper until you scan past
the last bar in the row. If you are new to wand-type devices, you may
experience scan errors frequently the first few times you use the wand.
However, taking some time to practice scanning bar code will help you
develop a scan technique that achieves satisfactory results.
Note: To conserve battery power, keep the scan switch pressed only while
you are scanning a row of bar code.
After each scan the HP-41C normally responds by sounding a short scan tone. But if the system detects an error during a scan, the
HP-41C responds instead with a prolonged scan error tone and, in most cases, a displayed error message.
Messages, describes error conditions and error recovery. If the HP-41C does not respond to a scan, check your scan angle and rescan
the row more carefully.
Using the Paper Keyboard
The Wand Paper Keyboard contains bar code that allows you to execute the individual functions resident in the HP-41C and its
peripherals.* Each function is scanned as a separate row, allowing you to use the wand for executing system functions you would
otherwise execute from the keyboard.
Example: Scan the following bar code to execute the indicated functions. (The example assumes a
