Step 1: Are You Sure You Want to Reset? Understand What a Reset Does
Before we press any buttons, it's crucial to understand what a "reset" on your TI BA II Plus actually entails. A full reset will clear all user-defined data, including:
Memory registers: Any values you've stored in the calculator's memory.
Worksheets: All data entered into financial functions like TVM (Time Value of Money), cash flow (CF), depreciation (DEPR), bond calculations (BOND), etc.
Custom settings: Changes you've made to display formats (e.g., number of decimal places), calculation methods (e.g., AOS vs. Chain), and other preferences.
Essentially, it restores the calculator to its factory default settings, just like it was when you first took it out of the box. This is a permanent action, so make sure you've saved any important data elsewhere if needed!
Step 2: The Basic Clear - Clearing Current Operations
Sometimes, you don't need a full factory reset, but rather just a clear of the current calculation or a specific worksheet. Let's explore these initial clearing options before moving to the full reset.
2a: Clearing the Display and Current Calculation
Press the [CE/C] key: This key serves two primary purposes depending on when you press it.
First press: If you've just entered a number or operation, pressing [CE/C] will clear only that entry.
Second press (or if the display is clear): Pressing [CE/C] a second time (or if the display is already clear of a specific entry) will clear the entire current calculation and return the display to zero. This is your go-to for simple mistakes.
2b: Clearing Specific Worksheets
The BA II Plus has various "worksheets" for different financial calculations. You might want to clear one without affecting others.
QuickTip: Don’t skim too fast — depth matters.
For TVM (Time Value of Money) and other financial worksheets:
Navigate to the desired worksheet (e.g., press [2nd] then [FV] for TVM).
Press [2nd] then [CLR TVM] (above the [FV] key): This will clear all the variables within that specific TVM worksheet (N, I/Y, PV, PMT, FV).
Repeat this process for any other worksheet you wish to clear individually (e.g., [2nd] [CLR WORK] for cash flow).
Step 3: Performing a Full Factory Reset - The Official Method
Now, for the main event: the full factory reset. This is the most comprehensive way to clear all data and settings.
3a: Accessing the Reset Function
Turn on your calculator: If it's off, press the [ON/OFF] button.
Press [2nd]: This activates the secondary functions printed above the keys.
Press [RESET] (above the [CLR TVM] key, which is above the [FV] key): You'll likely see "RST" or "RESET" briefly on the display, followed by "NO".
3b: Confirming the Reset
Once "RST" or "RESET" followed by "NO" appears, press [ENTER]: This confirms your intention to reset. The display will briefly show "RST" or "RESET" again, and then return to a blank screen or zero, indicating the reset is complete.
3c: Alternative Reset Method (If the above fails or for older models)
While the [2nd] [RESET] method is standard for most BA II Plus models (including the Professional), some users have reported an alternative that might work if you're having trouble or have an older version:
Press and hold [ON/OFF] and [CLR WORK] (above the [CF] key) simultaneously.
Release both buttons. This might perform a hard reset on some units. This method is less commonly cited in official documentation but has been shared by users as a troubleshooting step.
Step 4: Verifying Your Reset and Initial Setup
After performing a full reset, it's a good idea to verify that it was successful and set up some basic preferences.
4a: Checking for Default Settings
Tip: Reread if it feels confusing.
Decimal Places: The default is typically 2 decimal places. To check, press [2nd] then [FORMAT] (above the [.] key). The display should show "DEC=2.00" or similar.
Calculation Method: The default is Chain method. To check, press [2nd] then [FORMAT] again, then press the down arrow key ([]) until you see "Chn" or "AOS". It should be "Chn".
Memory: Try recalling a memory value by pressing [RCL] then [0] (or any number). It should display 0, indicating the memory registers are clear.
4b: Setting Your Preferred Decimal Places (Optional)
Most users prefer more than 2 decimal places for financial calculations.
Press [2nd] then [FORMAT].
Enter the desired number of decimal places (e.g., 4 for four decimal places).
Press [ENTER].
Press [CE/C] to exit the format menu.

4c: Setting Your Calculation Method (Optional)
The BA II Plus offers two calculation methods: Chain (Chn) and Algebraic Operating System (AOS). Chain is the default and typically sufficient for most users. AOS allows for more complex order of operations.
Press [2nd] then [FORMAT].
Press the down arrow key ([]) repeatedly until you see "Chn" or "AOS".
Press [2nd] then [SET] (above the [ENTER] key) to toggle between Chn and AOS.
Press [CE/C] to exit.
Most users stick with Chain unless they have a specific need for AOS.
Step 5: Troubleshooting Common Reset Issues
Sometimes, things don't go as planned. Here are some common issues and how to address them.
5a: Calculator Not Responding After Reset Attempt
Check the battery: A low battery can cause erratic behavior. Replace the battery if it's old or you suspect it's low.
Remove and reinsert battery: Sometimes, simply removing the battery for a minute or two and then reinserting it can resolve stubborn issues. Be sure to follow proper battery replacement procedures outlined in your calculator's manual.
Hard reset (if applicable): If your model supports it, try the [ON/OFF] + [CLR WORK] method again.
5b: Settings Not Resetting Correctly
Repeat the reset process carefully: Ensure you're pressing the correct sequence of keys ([2nd] then [RESET] then [ENTER]).
Verify by checking default settings: Go through Step 4a again to confirm the settings are back to factory defaults. If not, try the reset once more.
5c: Data Still Present in Worksheets
Tip: Pause whenever something stands out.
Did you perform a full factory reset? Remember, just clearing the display ([CE/C]) or individual worksheets ([2nd] [CLR TVM]) is not a full reset. You need to use the [2nd] [RESET] then [ENTER] sequence for a complete wipe.
Power cycle: Turn the calculator off, then back on, and re-check.
By following these steps, you should be able to effectively reset your Texas Instruments BA II Plus calculator and get it ready for your next financial adventure!
