How to Change a Price on a SAM4S ER-900 Cash Register
Follow these steps to permanently change a preset PLU price on a SAM4S ER-915E, ER-920E, ER-925E, ER-940E or ER-945E cash register. This guide also explains the difference between permanent PLU programming and using the PRICE CHANGE key during a sale.
Quick Answer: How Do I Change an ER-900 PLU Price?
For a permanent preset price change on many SAM4S ER-900 Series registers, turn the control lock to PGM, enter 200, press SBTL, select the PLU, enter the new price without a decimal point, press QTY/TIME, and press CASH to finish. Return to REG mode and test the item before using the register for normal sales. :contentReference[oaicite:0]{index=0}
Confirm What Kind of Price You Need to Change
The correct procedure depends on whether the item is a preset PLU, barcode item, keyboard PLU, open-price department or a one-time price adjustment during a sale.
| What You Need to Change | Typical Method | What to Confirm |
|---|---|---|
| Permanent preset PLU price | Program 200 PLU Price/HALO programming | Confirm the PLU number, barcode or keyboard PLU key |
| Keyboard item key | Select the item key during PLU programming | Confirm the key is a PLU and not a department or function key |
| Barcode item | Enter or scan the programmed PLU or UPC | Confirm the barcode already exists in the register |
| One-time sale price | PRICE CHANGE key, when programmed | Confirm the key exists and is enabled |
| Taxable or non-taxable setting | Separate PLU status programming | Changing a price does not normally change tax status |
| Open-price entry limit | HALO programming | Confirm whether the item is preset or open priced |
Do Not Clear the Register Memory
Changing an item price should not require a memory clear, initialization or reset. Those procedures can erase programming or sales totals. If the register rejects the price change, stop and confirm the model, mode and PLU setup before trying other programming codes.
How to Permanently Change a PLU Price
Use these steps when the item already exists and you want the register to remember the new price for future transactions.
-
Turn the control lock to PGM.
Use the proper program or manager key. Permanent PLU programming is normally completed in PGM mode, not REG mode. -
Enter Program 200.
Enter 2 0 0 and press SBTL. -
Select the item.
Press the keyboard PLU key, or enter the PLU number and press the appropriate PLU key according to the way the register is configured. -
Enter the new price.
Enter the amount without a decimal point. For example, enter 499 for $4.99 or 1299 for $12.99. -
Press QTY/TIME.
This accepts the price entry. A register configured with another price level may prompt for an additional price. -
Program another item or finish.
Repeat the item and price steps for another PLU, or press CASH to complete the program. -
Return to REG mode and test the item.
Ring the item in a normal transaction and confirm the price, tax, description and receipt are correct.
Example: Change a Preset PLU Price to $4.99
The basic sequence for many ER-900 Series configurations is:
Test the Price After Programming
Turn the control lock back to REG, ring the item and review the display and receipt. If the wrong item changed, the keyboard key, PLU number or barcode may not match the item you intended to edit.
Using the PRICE CHANGE Key During a Sale
The PRICE CHANGE key is different from permanent Program 200 PLU programming. It may be used to alter the price during the current transaction, but its exact behavior depends on the way the key and item were programmed.
Typical Sale Sequence
- Press PRICE CHANGE.
- Select or scan the item.
- Enter the adjusted price.
- Press PRICE CHANGE again.
- Review the displayed price before completing the sale.
Important Limitation
Using PRICE CHANGE during a transaction may not update the stored PLU price. If the item returns to its original price during the next sale, use permanent PLU price programming instead.
How to Change the Price of a Barcode Item
A barcode item can usually be changed if the UPC has already been programmed as a PLU. The way you select the item during Program 200 depends on the register configuration.
- Confirm the barcode already rings during a normal sale
- Write down or photograph the complete UPC
- Confirm whether the scanner can be used in PGM mode
- Enter or scan the correct UPC or PLU number
- Change one item and test it before changing additional items
- Check tax status separately from price programming
Scanner Beeps but the Item Is Not Found
The barcode may not be programmed, the scanner may not be active in PGM mode, or the register may use a different item-selection method. Do not create a second item accidentally without confirming the existing PLU setup.
Registers With More Than One Price Level
Some ER-900 installations use more than one preset price, such as regular and alternate pricing. When Program 200 prompts for another price after QTY/TIME, enter the second price and press QTY/TIME again before finishing.
Regular Price
The primary preset price normally used when the item is sold.
Alternate Price
A second configured price that may be selected by a function, employee or operating mode.
Open-Price HALO
A maximum permitted amount for an open-price item rather than a normal preset selling price.
If you are unsure which price field the register is requesting, stop before entering additional values and review the programming manual or request assistance.
Why the ER-900 Price Change May Not Work
| Problem | Possible Cause | What to Check |
|---|---|---|
| The register beeps or rejects the entry | Wrong mode, sequence, key or programming access | Confirm PGM mode and use of the correct program key |
| The price changes once but does not stay changed | The PRICE CHANGE sale function was used | Use Program 200 for a permanent preset PLU price |
| The wrong item changes | Incorrect PLU number, barcode or keyboard key | Confirm the item identity before changing more prices |
| The correct price rings with the wrong tax | Tax status is programmed separately | Review the PLU tax assignment rather than repeating the price change |
| The barcode item is not found | The barcode may not exist as a PLU | Test the item in REG mode and confirm the UPC |
| There is no PRICE CHANGE key | The function is not assigned to the keyboard | Keyboard-function programming or dealer help may be required |
| The register asks for another amount | A second price level or HALO field may be enabled | Confirm the register’s price-level setup before continuing |
Before Changing Several ER-900 Prices
- Print or save current programming when possible
- Use a written list of the old and new prices
- Change one item and test it first
- Confirm whether each item is a PLU, department or barcode item
- Confirm the tax assignment separately
- Review every changed item on a test receipt
- Keep the program key away from unauthorized users
- Do not initialize or clear memory to correct a price

SAM4S ER-900 Price Change FAQ
Which ER-900 models does this price guide cover?
The guide applies generally to the SAM4S ER-915E, ER-920E, ER-925E, ER-940E and ER-945E. Key positions and item-selection methods may vary by model and keyboard configuration.
What does Program 200 do?
Program 200 is commonly used for PLU Price/HALO programming on ER-900 Series registers. It can be used to change stored preset prices and related amount limits, depending on the item setup.
What does HALO mean?
HALO means High Amount Lock Out. It limits the amount that can be entered for an open-price item and helps prevent accidental excessive entries.
Why did my new price not stay in the register?
You may have used the PRICE CHANGE key during a transaction instead of permanent Program 200 PLU programming. Confirm the stored price by ringing the item again in a new sale.
Do I enter the decimal point when programming a price?
On many ER-900 configurations, prices are entered without a decimal point. For example, $4.99 is entered as 499. Confirm your register’s decimal configuration before changing several items.
Can I change the price of a scanned barcode item?
Yes, when the barcode is already programmed as a PLU and the register permits the item to be selected during programming. Confirm the exact UPC before changing the price.
Does changing the price also change the tax status?
Normally no. Price and tax status are separate programming settings. Test the item after changing the price to confirm the correct tax is still being applied.
Can SAM4S Direct help change my ER-900 prices?
Programming assistance may be available depending on the exact model, keyboard layout, item setup and requested changes. Provide the model number, a keyboard photo and details about the item you need to change.
