1. Overview
This WiFi 5G and Bluetooth 5.4 Dual Mode BBQ Thermometer is designed for versatile and convenient cooking. It features a unique combination of long and short probes: the black probe is ideal for roasting large meat joints, monitoring both internal food temperature and ambient oven temperature simultaneously. The white probe is perfect for smaller meats, fish, and delicate dishes, focusing solely on food temperature. This design ensures precise monitoring for perfect cooking results every time.
For safe use, the probes should be inserted past the safe cooking line. During operation, maintain a distance of no more than 6 meters (19.68 feet) between the probes and the base. If obstacles are present, shorten this distance for a stable connection.

6. Maintenance
6.1 Cleaning and Storage
- Probes: The probes are waterproof (IP67) and dishwasher safe. Clean them under running water or in a dishwasher after use. Avoid corrosive detergents. Ensure probes are dry before placing them back on the base to prevent damage to electrode plates.
- Base: The base is NOT waterproof. Do not rinse or submerge it in water. If necessary, wipe it with a slightly damp cloth.
- Storage: Place probes inside the charging base and store the entire unit in a cool, shaded place, away from children. Improper storage can cause damage or injury.
6.2 Battery Details & Charging
- Probe Battery: Each probe provides up to 25 hours of continuous monitoring when fully charged. Charging takes approximately 25 minutes. Consistently high temperatures may reduce battery life.
- Base Battery: The base has a built-in 2500mAh lithium battery, providing over 55 hours of battery life. Charging takes approximately 3 hours using the provided USB-C cable (5V 1.5A).
- Charging: Use the provided USB-C cable to charge the device. The indicator light on the base will flash green while charging and remain solid green when fully charged. If using a different cable, ensure it is Type-C and provides 5V 1.5A.
- Low Battery: If the probe's battery is low, clean and dry it before placing it back on the base for charging. If the base's battery is low, charge it using the provided cable. The LCD screen will display the charging status of both.
- Long-term Storage: If storing the device for an extended period, charge the battery to 50% capacity to prevent deep discharge. Avoid fully charging before storage, as this may shorten battery lifespan.
