Directions for Use and Care of Class 300

National Cash Registers Installation

A National is the simplest and best cash register on the market today, and when properly installed and given attention as directed herein will give years of service.

A thorough understanding between yourself and your clerks as to just what the register does, how it operates, and care it should receive is absolutely necessary.

The register should be placed in a position convenient to all of your clerks and so the indication can be seen plainly by your customers. After the location has been decided upon, proceed as
follows:

Locks

The locks for this register are numbered 1, 2, 3 and 5, these numbers being cast on the cabinet.

Lock No. 1 controls the lid over the adding counter.
To unlock, turn key a half turn to the right.

Lock No. 2 on left side controls the mechanism, making the machine inoperative.
To unlock, turn key a half turn to the left.

Lock No. 3 on left side in front of Lock No. 2 controls the ringing of the bell.

Lock No. 5 locks hood over the detail strip printer.
To unlock, turn key to the left.

Attach glass top and top sign and the register is ready for operation.
Do not remove the rubber bands from the glass. They act as cushions.

To Operate Register

To record a cash sale of 50c press 50c key all the way down, remove finger from key and it will automatically return to position, bell will ring, cash drawer will open and indication will show amount of sale, which will be added on the counter and printed on the detail strip.

To register amounts requiring two or more keys, say $1.50, both keys must be started at the same time. After keys are pressed part way down, registration may be completed by pressing either key single.

Cash Drawer

Press “No‑Sale” register key all the way down, release same and cash drawer will open.

To operate the register with the cash drawer open or closed, insert turn‑to‑zero key in slot in the end of rod through opening No. 7 and. turn to right until it comes to a stop.

To remove cash drawer pull drawer out full length and raise the steel rod at the back end of the compartment.

To release cash drawer, raise the lid and press down on end of rod extending through guard near the center and the drawer will open.

Special Keys and Counters

The “No‑Sale” counter (under lid) shows the number of times the “No‑Sale” key is operated. Each time this key is pressed 1 is added to the amount previously shown on the counter. The same applies to other special keys. These counters show the proprietor the number of registrations made on each special key.

The customer counter adds 1 each time the register is operated, thus the total number of registrations of every kind is shown.

To find the number of cash sales made, deduct from the amount on the customer counter the total number recorded on the special key counters.

Some registers have special keys (as “Received on Account,” “Charge,” “Paid Out,” etc.) to operate with amount keys and to print a character on the detail strip. These keys are arranged so that they can be pressed only half‑way down and registration is completed by pressing the amount keys.

Some registers are equipped with a “throw‑out device” for special keys. The amounts registered in connection with these special keys are not added into the cash counter, but the amount and character representing the key are printed on the detail strip. For example, to register a
“Charge” transaction of $4.50, you first press the “Charge” key as far as it will go, then press the “$4” key and the “50c.” key together. The register will indicate, “Charge $4.50,” and print on the detail strip “4.50 C,” but the amount will not be added into the total adding counter.

Lid Counter

The lid counter records the number of times the lid of the register is opened, counting 1 each time the lid is raised. It is set directly under lid of register close to hinged edge.

Each time you take the statement from register, record number shown by lid counter. When taking the following day’s statement the lid counter should show the next consecutive number. If any other number is shown it is evidence that someone else had access to interior of register. This counter registers up to 99,999 then automatically resets to zero.

Resetting Register to Zero

Place in the hole in guard under lid of register the key marked “Turn to Stop.” Push key down
firmly with teeth to the right. Turn key to right until it comes to a stop. Adding wheels will then show zero. Be sure to turn key to stop, as registering keys cannot be operated unless counter is set to zero. Be sure that all adding wheels show zero after resetting.

The special counters are reset to zero by turning from you the knurled wheels which extend through the guard.

To Get Statement of Day’s Business

Unlock and raise lid of register, open cash drawer. Unlock hood over detail strip. Take out the amount of money placed in cash drawer for change. Write in statement book the amount of cash sales as shown by the total‑adding counter. From this amount deduct total cash paid out as shown by the paid‑out slips. The balance will show the amount of money that should be in cash drawer.

Enter in space provided the numbers shown by special counters and lid counter. These numbers should agree with the number of slips in drawer. Remove printed part of detail strip which should be dated and filed for future reference. Close hood, reset adding counters, close and lock lid.

Register is now ready for next day’s business.

Remove all money and records from cash drawer at close of each day’s business. Leave cash drawer open at night, as thieves might break it open.

To Space Detail Strip

Push in knob on outside of hood. Hold in position; at the same time give half a turn to left. This will wind paper forward. A blank space will be shown on detail strip. By this means you can get a record of sales recorded during any given hour of the day.

To Remove Detail Strip

Unlock and open hood at right of register. Turn receiving roll “A” forward until printed amounts are all wound upon the spool. Pull out key “A,” break paper, remove printed strip by pressing it lightly and pull it off stud. Secure loose end of remaining paper by drawing it forward over groove in stud. Place long‑end of key “A” in groove (on top of paper) and short end of key “A” in
hole in end of stud. Give key one turn to left to fasten paper securely.

To Supply New Roll of Paper

Remove thumb‑screw “B” by turning to left. Take off old wooden core. Place new roll of paper on spool, pushing it on as far as it will go. Paper must unwind from roll as shown in cut. Replace
thumb­screw “B,” screwing it up tight. Pass end of paper forward under ribbon and over guides “1” and ” 2″ and fasten to stud with key “A” as previously explained.

To Supply New Ribbon

• Remove thumbscrew “H”
• Take off old ribbon.
• Lift swinging roller “F”
• Place new ribbon around roll “E,” under stud 3 (see cut) and over roller in rear of printing device.
• Place thumb‑screw “H” under ribbon and screw firmly in place.

To Put in New Impression Block

Press “No‑Sale” key part way down.
This will lower hammer. Loosen screw in front of hammer, remove old block, put
in new block and tighten screw.

Page 13

Care should be taken in putting in block to see that it strikes through the opening in the steel guide over which the paper passes. The register should not be operated without the detail‑strip paper in position; otherwise the impression block becomes worn and uneven.

To Print Receipt for Receipt Printing Registers

Insert receipt about three inches or to first guide line, printed side up through opening in front of hood. Operate register as usual and withdraw receipt. . Amount of registration will be printed on receipt, but not on detail strip.

If second or third amount is required on same receipt it should be inserted to second or third guide line.

To Clean Register

Clean nickel‑plated cases only with warm water and soap, dry with soft cloth and polish with a piece of chamois skin.

Never clean copper oxidized or lacquered cases with anything but warm water and dry thoroughly with soft cloth. Most cleaning preparations contain alcohol or ammonia, which cannot be used without damaging the case.

Directions for Two‑Counter Locks

The cut shows the location of Locks “A” and “B” on register equipped with counter locks. When the register is received, both “A” and “B” Locks are unlocked, so that amounts can be registered on either the right‑hand counter, “A,” or the left‑hand counter, “B,” as follows:

(1) If amounts are to be registered on the right‑hand or “A” counter, simply press the registering keys representing the amounts to be registered.

(2) If amounts are to be registered on the left‑hand or “B” counter, the push button (which is located on the right and a little below the line of the registering keys) MUST be pushed in as far as it will go. The push button will remain in until the registration has been made, when it will automatically return to its normal position.

When the register is to be used by only one clerk at a time, and all the amounts registered on one counter, the other counter can be locked out so that it is impossible to register any amounts on it, as follows;

(1) If clerk “A” is to operate the register, lock the “B” Lock by turning the key from you and remove the key. This will prevent clerk “A” from pushing in the push button and registering on counter “B.”

When clerk “A” goes off duty he will lock Lock “A” by holding in the push button and turning the key to the right and remove the key. By locking Lock “A” the register becomes inoperative.

(2) When clerk “B” comes on duty he will unlock Lock “B” by turning the key toward him. He will then push the push button in as far as it will go and lock the

Page 16

“B” Lock, when all registrations made will be registered on counter “B.”

When clerk “B” goes off duty he will unlock Lock “B” (which will release the push button, allowing it to come part way out). He will then lock Lock “B” which will leave the register inoperative.

When clerk “A” comes on duty he will unlock Lock “A,” which will allow the push button to come to its normal position.

Two sets of keys are furnished for Locks “A” and “B.” The proprietor is to retain one set, and clerks “A” and “B” are each to have their respective keys.

Important

If you do not understand these directions, or if you have any trouble with your register do not tinker with it, but notify the agent. Keep register out of a damp place and free from water.

Remove money from register at night and leave drawer open, so burglars if they break in, will not damage register.
