Setup

Battery Installation

• Main Unit: Requires 2 AAA batteries (not included). Open the battery compartment on the back of the main unit and insert the batteries, observing polarity.
• Wireless Sensors: Each sensor requires 2 AA batteries (not included). Open the battery compartment on the back of each sensor and insert the batteries, observing polarity.

Image: Ensure correct battery insertion for both the main unit and the wireless sensors. The main unit uses AAA batteries, and sensors use AA batteries.

Pairing Sensors

• Place the main unit and sensors close to each other during initial setup.
• The sensors should automatically connect to the main unit. A signal indicator on the transmitter will confirm connection.
• If the screen does not display content, ensure the transmitter is connected to the host.
• Important Note: If using multiple ORIA thermometer sets, install one set completely and ensure it's connected firmly before installing another set to avoid signal conflicts.

Operating Instructions

Display Overview

The LCD screen displays indoor temperature, and temperatures from Sensor 1 and Sensor 2 simultaneously.

Image: The clear LCD provides real-time temperature readings for indoor, Sensor 1, and Sensor 2, along with maximum and minimum recorded temperatures.

Temperature Unit Selection (°C/°F)

Press the "+/°C/°F" button on the main unit to switch between Celsius and Fahrenheit display.

Max/Min Temperature Records

The main unit automatically records the maximum and minimum temperatures for indoor, Sensor 1, and Sensor 2 over a 24-hour period.

To clear the Min/Max temperature data, quickly press the "CLEAR" button once. New data will begin to update.

Setting Audible Alarms

The thermometer features an audible alarm function for each sensor and the indoor temperature.

1. Press and hold the "ALARM INDOOR", "ALARM SENSOR1", or "ALARM SENSOR2" button for 3 seconds to enter temperature alarm setup mode for the respective channel.
2. The MAX value will flash. Use the "+" or "-" buttons to set your desired maximum alarm temperature. Press the same alarm button again to confirm.
3. The MIN value will then flash. Use the "+" or "-" buttons to set your desired minimum alarm temperature. Press the same alarm button again to confirm and exit setup.
4. The alarm function will activate 10 minutes after being turned on to prevent false alarms from temporary temperature changes (e.g., opening a freezer door).

Image: Customize alarm thresholds for each sensor and indoor temperature. The alarm will sound if temperatures exceed or fall below your set limits.

Placement and Mounting

The main unit offers versatile placement options:

• Magnetic Back: Integrated magnets allow it to be attached to metal surfaces like refrigerator doors.
• Hanging Hole: A built-in hole on the back allows for wall mounting.
• Fold-out Bracket: A retractable stand enables tabletop placement.

Image: The main unit can be conveniently placed on a table using its stand, mounted on a wall via its hanging hole, or attached to a metal surface with its strong magnets.

Sensor Placement

Place wireless sensors inside your refrigerator, freezer, or any outdoor area where temperature monitoring is desired. Ensure sensors are protected from direct moisture.

Image: The wireless sensors are designed to be placed inside appliances like refrigerators and freezers to monitor internal temperatures.

Maintenance

• Cleaning: Wipe the thermometer and sensors clean with a soft, damp cloth. Do not use abrasive cleaners or immerse in water.
• Battery Replacement: Replace batteries when the display starts to blur or readings become inconsistent to ensure accuracy.
• Placement: Place the thermometer properly to prevent the screen from being crushed or damaged.
