KNOW YOUR DEVICE A1: Power Switch A2: Display Screen A3: Probe A4: Probe Charger A5: Channel Switch A6: Power Output Port A7: Power Input Port B1: Built-in Magnet B2: Stand Back Cover B3: Reset Button Note: You can use a Type-C charging cable to charge the Stand through the Power Input Port, and let the Stand charge other electronic devices

(such as mobile phones) through the Power Output Port. 06 4.1 THE PROBE Made of stainless steel and zirconia ceramic, the wireless probe has sensors for reading both the internal temperature of your food (where the probe is inserted) and the ambient temperature (the temperature of the air surrounding your food). The internal temperature sensor is positioned at the tip and has a range of 32F to 212F (0C to 100C). The ambient temperature sensor is housed toward the ceramic end and has a range of 122F to 662F (50C to 350C). It's also accurate to 1F

(0.5C) for internal measuring. The probe can stay powered for 30 hours after a full charge. 4.2 THE STAND The Stand not only charges the probe but also relays temperature data from the probe to the ChefsTemp App. For best results, position the Stand close to the probe during cooking. The Stand stays powered for 80-100 hours with Wi-Fi transmission. 4.3 THE CHEFSTEMP APP Although ProTemp Plus can be used independently to measure food temperature, you need to use the ChefsTemp App to set target temperatures and alarms. The App must be downloaded onto your smartphone or tablet. Once paired with the Stand and probe, the App will display live temperature readings, which you can view from anywhere

(using Wi-Fi or Bluetooth). You can set preset or customized target temperatures to receive an alarm on your phone when food is ready. 07 5. GETTING STARTED Step 1: Use a Type-C charging cable to charge the Stand. The Stand requires about 4-5 hours to fully charge. Make sure the AC adapter is 5V 2A or 12V 1A. Step 2: Insert the probe into the charger on the Stand to charge it, and allow the probe to charge for a minimum of 1 hour. Step 3: While the Stand and probe are charging, download the ChefsTemp App from the Apple App Store or Google Play Store. You can scan the following QR code to find it. Note: Works with iOS 11 or later and Android 9.0 or later. iOS Android Step 4: Open the App, register your account, and log in. Step 5: Tap Add your device and follow the on-

screen instructions to set up and activate your ProTemp Plus. 08 6. SET UP YOUR PROTEMP PLUS Step 1: Press and hold the power switch to activate the charging Stand. Step 2: Take out the probe from the charger. Step 3: Press and hold both switches until the screen displays C-1 to activate Bluetooth. Step 4: Wait for the Stand to link to Bluetooth (C-2 appears on the screen). 09 Step 5: When the Stand shows C-5, tap Connect your Wi-Fi. After the SSID appears automatically, enter your Wi-Fi password, tap Next, and wait for the Wi-Fi connection. How to add a new probe?

Place the probe that needs to be added on the Stand for charging. After charging, remove the probe and open the App. Tap the button in the upper right corner of the main page, and tap Add Devices, then select the probe you want to add. 10 7. COOKING WITH THE PROTEMP PLUS For best cooking results, please follow these steps:

Step 1: Ensure the Stand is charged and turned on, and the probe is charged. Step 2: Preheat your cooking appliance as needed, prep your ingredients, and season your food as desired or directed. Step 3: Place the Stand near (but never in or on) the cooking appliance. In open space, the maximum transmission distance is 500ft (190m). If the probe is in a closed environment, such as an oven or closed grill, the distance will be shortened to less than 15ft (6m). Therefore, we recommend the Stand be placed next to the probe as close as possible. Be aware that the Stand shell is plastic, therefore it can melt if placed too close to the heat source. Step 4: Set the temperature as desired via the App. You can either quickly set a preset temperature or customize your target temperature. Step 5: When ready to cook, insert the probe into the thickest part of your food, avoiding any bones. Be sure the tip, which is where the internal temperature sensor is located, is positioned in the food properly for the most accurate reading. Note: Always insert the probe past the safety notch. Ensure the probe is firmly inserted and not loose before cooking. 11 Step 6: Cook your food. When cooking, be sure that the end of the probe, which houses the ambient temperature sensor, is not directly touching the heat source or any hot surfaces (such as the grates on a grill or the sides or edges of pots and pans). Although it's heat resistant to 662F (350C), the probe can be damaged at temperatures beyond that. Step 7: Follow your cooking progress on your smartphone or tablet. Step 8: Cook your food until done. You'll get an alert when it's time to take your food off the heat. Step 9: Remove the probe carefully. When it's time to remove the probe (usually after the food has rested), be extremely careful as it may still be hot and can cause burns. Use a towel, potholder, or oven mitt when pulling the probe out of the food. Note: If the probe is difficult to remove, pull and twist the end. Do not bend the probe against the meat. 8. CLEANING AND MAINTENANCE When not in use, place the Stand in a cool and dry environment and insert the probe into the charger for charging, and ensure the probe is thoroughly cleaned and dried. The charging contacts need to be kept smooth and clean. When charging the Stand, ensure that the power input port and Type-C charging cable plug are clean and dry, and the Stand is in a cool place and has cooled down. Exposure to sunlight may prevent the bracket from charging due to high temperatures. Manually clean the probe with soapy water, and if there are stubborn residues that are difficult to clean, you can use a polishing sponge or finer sandpaper for cleaning. 12 If the Stand gets dirty, wipe it down with a damp cloth. The Stand is not dishwasher-safe and is not waterproof. Do not immerse it in water. If you don't use ProTemp Plus for a long time, please charge it at least once within 1-2 months. Long periods without charging may lead to damage to the internal lithium battery. 9.
