How Do I Reset an Exergen Temporal Scanner? Mastering Accurate Temperature Readings
Resetting an Exergen Temporal Scanner is typically not required for standard use; however, in rare cases of malfunction or persistent errors, a power cycle might be needed. This involves briefly removing and reinserting the batteries to reinitialize the device and restore accurate temperature readings.
Understanding the Exergen Temporal Scanner
The Exergen Temporal Scanner is a non-invasive thermometer that measures temperature by scanning the temporal artery in the forehead. Its accuracy and ease of use have made it a popular choice for both medical professionals and home users, particularly for infants and children. Unlike traditional thermometers, it doesn’t require insertion into the mouth, rectum, or armpit, minimizing discomfort and reducing the risk of spreading germs. However, like any electronic device, it can occasionally experience glitches that may affect its accuracy. While a full “reset” in the traditional computer sense isn’t usually performed, troubleshooting often involves checking the batteries and performing a power cycle. Knowing how do I reset an Exergen Temporal Scanner properly can help resolve such issues.
Benefits of Using a Temporal Scanner
Temporal artery thermometers like the Exergen offer several advantages:
- Non-invasive: Minimizes discomfort, especially for children.
- Fast Readings: Provides temperature readings in seconds.
- Accurate: Measures core body temperature.
- Hygienic: Reduces the risk of cross-contamination.
- Easy to Use: Simple operation, even for beginners.
Diagnosing Potential Issues Requiring Attention
Before attempting any troubleshooting steps, it’s important to understand when a “reset” might be helpful. Erratic readings, persistent error messages, or a complete failure to power on are indications that the scanner may need attention. However, it’s equally important to rule out other factors, such as low batteries or improper technique.
The “Reset” Process: A Power Cycle
While not a traditional factory reset, a power cycle often resolves minor software or electronic glitches. Here’s how to perform one:
- Turn Off the Scanner: Ensure the scanner is powered off.
- Locate the Battery Compartment: This is usually on the handle of the device.
- Remove the Batteries: Carefully remove all batteries from the compartment.
- Wait Briefly: Allow the scanner to sit without batteries for at least 60 seconds. This allows any residual power to dissipate.
- Reinsert the Batteries: Ensure the batteries are inserted correctly, matching the positive (+) and negative (-) markings.
- Power On the Scanner: Turn the scanner back on and test it to see if the issue has been resolved.
Common Mistakes and Troubleshooting Tips
- Low Batteries: The most common cause of inaccurate readings or malfunction. Always replace with fresh batteries.
- Improper Technique: Ensure the scanner is held flush against the forehead and moved smoothly across the temporal artery. Refer to the user manual for correct technique.
- Dirty Lens: A dirty or smudged lens can affect accuracy. Clean it gently with a soft, dry cloth.
- Ambient Temperature: Extreme temperatures can affect readings. Allow the scanner to acclimatize to room temperature before use.
- Software Problems: While rare, software glitches can occur. The power cycle mentioned above typically resolves these issues. If problems persist, consult Exergen’s official support channels. This information helps users understand how do I reset an Exergen Temporal Scanner even if that means identifying other problems besides a reset.
When to Seek Professional Help
If you’ve tried the power cycle and other troubleshooting steps, and the scanner still isn’t working correctly, it may be time to contact Exergen customer support or consult a qualified technician.
How To Maintain Your Exergen Temporal Scanner

- Store the scanner in a cool, dry place, away from direct sunlight.
- Clean the lens regularly with a soft, dry cloth.
- Replace the batteries when they are low.
- Avoid dropping or exposing the scanner to extreme temperatures or humidity.
- Follow the manufacturer’s instructions for use and care.
Frequently Asked Questions (FAQs)
Can I perform a factory reset on my Exergen Temporal Scanner?
No, Exergen Temporal Scanners do not have a traditional factory reset function like computers or smartphones. The primary method for addressing issues is a power cycle, which involves removing and reinserting the batteries.
Why is my Exergen Temporal Scanner giving me inaccurate readings?
Inaccurate readings can be caused by several factors, including low batteries, incorrect technique, a dirty lens, or ambient temperature fluctuations. Ensure you’re using the scanner correctly, replacing batteries as needed, and cleaning the lens regularly.
How often should I replace the batteries in my Exergen Temporal Scanner?
Battery life depends on usage frequency. As a general rule, replace the batteries every 6-12 months, or sooner if you notice the scanner is giving low battery warnings or inaccurate readings.
What type of batteries does the Exergen Temporal Scanner use?
Exergen Temporal Scanners typically use standard alkaline AAA batteries. Refer to your scanner’s user manual for specific battery requirements.
How do I clean the lens of my Exergen Temporal Scanner?
Use a soft, dry cloth to gently wipe the lens. Avoid using harsh chemicals or abrasive materials, as these can damage the lens.
What if the screen on my Exergen Temporal Scanner is blank?
First, ensure the batteries are properly installed and have sufficient power. If the screen remains blank, try removing and reinserting the batteries (performing a power cycle). If the problem persists, contact Exergen customer support.
Is there a warranty on Exergen Temporal Scanners?
Yes, Exergen offers a limited warranty on its Temporal Scanners. The specific terms and duration of the warranty may vary, so consult your scanner’s documentation or the Exergen website for details.
Can I use my Exergen Temporal Scanner on someone who has just exercised?
It’s best to wait at least 30 minutes after exercising before taking someone’s temperature. Physical activity can temporarily elevate body temperature, leading to inaccurate readings.
What is the normal temperature range when using an Exergen Temporal Scanner?
The normal temporal artery temperature range is generally considered to be around 94°F to 100°F (34.4°C to 37.8°C), although this can vary slightly depending on individual factors. Always consult a healthcare professional for any health concerns.
How do I know if my Exergen Temporal Scanner is working correctly after I’ve followed the process to reset it?
Take a temperature reading and compare it to readings taken with another thermometer or other reliable source. If the readings are within a reasonable range, the scanner is likely working correctly. If readings are wildly inaccurate, or persistent error messages appear, further investigation or professional assistance is needed.
Can I use my Exergen Temporal Scanner on infants?
Yes, Exergen Temporal Scanners are safe and effective for use on infants. They are especially convenient for taking temperature readings without disturbing sleeping babies.
What if my Exergen Temporal Scanner continues to show an “Err” message after power cycling?
If an “Err” message persists after a power cycle and fresh batteries, it indicates a more serious malfunction and necessitates contacting Exergen customer support or a qualified technician. Attempting further repairs yourself is not recommended.
