SAM4S ER-900 Price Programming
How to Change Prices on a SAM4S ER-900 Cash Register
Need to change an item price on a SAM4S ER-900 Series register? This guide explains the difference between permanently changing a PLU price in programming mode and using the PRICE CHANGE key during a sale.
The steps can vary by model, keyboard layout, PLU setup, manager key position, and how the register was originally programmed. Always confirm your exact model before changing register programming.
Permanent Price Change
Use this when you want the register to remember the new item price for future sales. This is usually done through PLU price programming.
Temporary Sale Price
Use this when you only need to change the price while ringing a sale. This depends on the PRICE CHANGE key and the way that key is programmed.
Programming Help
If the register rejects the entry, the item may not be preset correctly, the key may be inactive, or the register may need model-specific programming help.
Quick Answer
For a permanent item price change on many SAM4S ER-900 Series registers, turn the control lock to PGM, use 200 and SBTL to enter PLU Price/HALO programming, select the PLU, enter the new price, press QTY/TIME, and finish with CASH.
Before You Change a Price
Take a minute to confirm what you are changing. Most price problems come from confusing PLUs, keyboard item keys, barcode items, departments, open-priced items, and temporary price-change functions.
| What You Need to Change | Common Method | What to Confirm First |
|---|---|---|
| Preset PLU price | PLU Price/HALO programming | Confirm the PLU number, barcode, or keyboard PLU key. |
| Keyboard item key | Select the item key during PLU programming | Confirm whether the key is a PLU, department, menu key, or function key. |
| Barcode item | Enter or scan the PLU/UPC depending on setup | Confirm the item already exists in the register. |
| One-time price during a sale | PRICE CHANGE key | Confirm the key exists and is allowed by programming. |
| Taxable or non-taxable status | PLU status programming | Price and tax status are separate settings. |
How to Permanently Change a PLU Price on a SAM4S ER-900
Use this section when the item already exists and you want the register to remember a new preset price.
Example: Change a PLU Price to $4.99
This is a simple example for a preset PLU. Your exact key labels may vary.
PGM → 2 0 0 → SBTL → select the PLU → 4 9 9 → QTY/TIME → CASH
After finishing, test the item in a normal sale. If the wrong item changed, the item key, PLU number, barcode, or keyboard layout may not match what you expected.
Using the PRICE CHANGE Key During a Sale
The PRICE CHANGE key is different from permanent PLU programming. It is used while selling an item, and its behavior depends on how the register was programmed. In some setups it may only change the price for the current sale. In other setups it may be configured to always or prompt to permanently change the item price.
Common PRICE CHANGE Sale Sequence
Why the Price Change May Not Work
| Problem | Possible Cause | What to Check |
|---|---|---|
| The register beeps or rejects the entry | Wrong mode, wrong key sequence, inactive key, or restricted programming access | Confirm the control lock is in PGM for permanent changes and that you are using the correct manager key. |
| The price changes during the sale but does not stay changed | You used the PRICE CHANGE key instead of permanent PLU programming | Use Program 200 for a stored PLU price change. |
| The wrong item changed | The PLU number, barcode, or keyboard item key was not the item you expected | Print or review a PLU list before making multiple changes. |
| The item rings at the right price but wrong tax | Tax status is separate from price programming | Review taxable and non-taxable PLU status before changing tax-sensitive items. |
| The scanner item is not found | The barcode may not be programmed as a PLU | Confirm the item exists before trying to change the price. |
| There is no PRICE CHANGE key | The function may not be assigned to the keyboard | Function key assignment or dealer programming may be needed. |
Good Practice Before Changing Many Prices
If you are changing more than one or two prices, slow down and confirm the setup first. A small keying mistake can affect multiple items.
- Print or save current programming if your register setup allows it.
- Change one item first and test it before changing a group of items.
- Use a written price list so the cashier does not rely on memory.
- Confirm whether items are PLUs, departments, open-priced keys, or barcode items.
- Check tax status separately from price.
- Run a test sale and review the receipt before reopening the lane.
When to Get Help
Price changes are usually simple once the register layout is understood. Get help before changing settings if the register has a barcode scanner, multiple price levels, food service menu keys, taxable and non-taxable items, age-restricted products, clerk controls, or a custom keyboard layout.
SAM4S Direct can help you identify the model, find the right manual section, understand whether you need PLU programming or the PRICE CHANGE key, and decide whether your register should be reprogrammed, replaced, or upgraded to SAM4POS or a full POS system.

SAM4S ER-900 Price Change Frequently Asked Questions
Is changing a price the same as changing a PLU?
Not always. A PLU can include a price, description, tax status, group assignment, stock setting, and other options. Changing the price only updates the price portion unless you change other programming too.
What does Program 200 do on a SAM4S ER-900?
Program 200 is commonly used for PLU Price/HALO programming. For preset items, this is where the stored PLU price is changed.
What is HALO?
HALO means High Amount Lock Out. It is a limit used for open-priced entries so cashiers cannot accidentally ring an amount above the allowed limit.
Why did the price not stay changed?
You may have used the PRICE CHANGE key during a sale instead of permanent PLU programming. The PRICE CHANGE key behavior depends on the way the function and item are programmed.
Can I change prices for barcode items?
Yes, if the barcode item is programmed as a PLU and your register is set up for that workflow. Confirm the barcode or PLU number before changing the price.
Do I need to change tax when I change a price?
Usually no. Price and tax status are separate settings. If the item is taxable, non-taxable, food tax, or subject to special rules, confirm the tax setup before making changes.
Can SAM4S Direct program my ER-900 register?
SAM4S Direct can help you understand the correct manual section, identify common programming issues, and decide whether support, replacement, SAM4POS, or a full POS system is the best path.
