HP-41C programs, data and even individual HP-41C calculator functions. So that you can fully use the wand’s capabilities in your HP-41C system, take time to work through the few pages in this manual. You will find the wand simple to operate, yet useful in a wide range of applications.
How to Operate the Wand The bar patterns in HP-41C bar code rows are coded forms of programs, data, or functions. The information in the bar code is read into the calculator by scanning the bar code with the tip of the wand. Although you can scan in either a left to right or right to left direction, you may notice slightly better results using the left to right scan direction.
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.
Scanning Data Bar Code When you scan a row of data bar code, the data is entered in the HP-41C in the same manner as when you enter data from the keyboard. Scan the following bar code to enter the approximate speed of light in kilometers per second.
0.0000 To load bar coded numeric or ALPHA data lines in program memory, set the HP-41C to PRGM mode, then scan the data bar code. Numeric data is stored in program memory as a numeric entry. ALPHA data is stored in program memory as an ALPHA string.
, then 0.0000 Ensure that the HP-41C is not in PRGM mode, then use the following bar code to execute the program to calculate the volume in cubic meters of a tank 3.4 meters in diameter and 4.6 meters long.*...
Wand Functions The wand functions are contained in the wand circuitry and become active in the HP-41C system whenever the wand is plugged into the HP-41C. Wand functions may be executed manually or under program control in the same manner as other HP-41C functions. All can be terminated early by pressing keys.

Load and execute the program using the following bar code. Then scan the bar code in a square of the checkerboard illustration on the next page and view the corresponding square identification in the HP-41C’s display. (The bar code row in each square consists of the binary equivalent of a two-digit decimal number that identifies the square by row and column.) The above program could be modified...

WNDSCN WNDTST wand test function lets you test the wand of any HP-41C bar code by displaying what has been read in a row you WNDTST scanned. To use this test, execute and scan a row of bar code. Then note and compare each set of digits returned in the WNDTST HP-41C’s display with the corresponding bar pattern in each consecutive byts of eight bars in a row.
WNDTST WNDTST displayed byte values. If you doe not use a printer, but want the HP-41C to halt for each byte value display instead of pausing, set flag 21 before executing . After the first byte value appears, execute...
2. While the wand is removed, these functions are displayed in PRGM mode as a function called XROM. An XROM function tells the HP-41C that the function belongs to some plug-in accessory. Next to the XROM function name are two numbers.
Most scan errors are caused by slow or uneven scanning, inaccurate scans, i.e., missing some of the bars in a row, excessively tilting the wand, or by defective bar code. When the wand detects a scan error condition, the HP-41C sounds the prolonged scan error tone, and, in most cases, displays an error message.

Power Draws less than 50 mA at 5V from the HP-41C’s batteries when the scan switch is pressed (HP-41C turned on or off). The wand’s cumulative effect on the HP-41C’s batteries varies with the frequency and duration of use, but can be significant with heavy use.
CAUTION Do not insert your fingers or any objects other than an HP module or plug-in accessory into any port. To do so could alter the Continuous Memory or damage the port of the calculator. Always keep the port caps in place over any module ports you are not currently using.
7. Examine the HP-41C’s module ports and wand module contacts for obstructions or damage. 8. If you are unsure as to the source of the problem, you may want to take your HP-41C and the HP 82153A Wand to your nearest authorized HP retail dealer prior to sending the unit in for service.
HP 82153A - Wand Owner Manual - page 26 Wat Is Not Covered The warranty does not apply if the wand has been damaged by accident or misuse, or as a result of service or modification by other than an authorized Hewlett-Packard repair center.
If you happen to be outside of the country where you bought your wand, you can contact the local Hewlett-Packard repair center to see if HP 82153A Wand service is available. If service is unavailable, please ship your wand to the address listed under ‘‘In the United States,’’...
