• 2. Outdoor Temperature Display: Measures and displays outdoor temperature within the range of -40°C (-40°F) to 60°C (122°F).
• 3. Indoor/Outdoor Humidity Display: Measures and displays humidity levels from 10% to 99%.
• 4. Indoor/Outdoor Temperature Trend: Indicates whether the temperature is increasing, decreasing, or remaining stable.
• 5. Indoor/Outdoor Humidity Trend: Indicates whether the humidity is increasing, decreasing, or remaining stable.
• 6. Low Battery Indicator: Alerts the user when the batteries in the main unit or remote sensor are low.
• 7. Backlight: Illuminates the display for improved readability in low light conditions.
• 8. 3 Channels for RF Cycle Display: Supports receiving data from up to three wireless remote sensors simultaneously.
• 9. Today/48Hr/All-Time Outdoor/Indoor Temperature/Humidity History: Allows users to review past temperature and humidity readings.
• 10. Temperature Unit °C/°F Switch: Enables switching between Celsius and Fahrenheit for temperature readings.

Setting Up Power Supply

Main Unit Setup

1. Remove the battery compartment cover from the main unit.
2. Insert two AAA batteries (not included), ensuring correct polarity [plus-minus-symbol].
3. Replace the battery compartment cover.

Remote Sensor Setup

1. Remove the battery compartment cover from the remote sensor.
2. Insert two AAA batteries (not included), ensuring correct polarity [plus-minus-symbol].
3. Set the channel selector switch on the sensor to the desired channel (1, 2, or 3).
4. Replace the battery compartment cover.

Channel Select

In normal operating mode:

1. Press the CH button (Button B) to select Channel 1, Channel 2, or Channel 3.
2. Hold the CH button for approximately 3 seconds to reset values and initiate a search for an RF signal from the sensors.
3. When the circle symbol [cycle-symbol] appears after holding the button, the thermometer will display a three-channel loop.

°C/°F Switch / History Display

Use Button C for unit and history functions:

1. In normal mode, hold and press Button C for approximately 3 seconds to switch the temperature unit between °C and °F.
2. Press Button C to switch the display between Today's, 48-hour, and All-Time historical data.

MAX/MIN Temperature and Humidity

Use Button D for maximum and minimum value functions:

1. In normal mode, press Button D to check the maximum and minimum temperature and humidity history.
2. Press and hold Button D for 3 seconds to clear the current temperature and humidity history.

Backlight

When the unit is powered by batteries, press the LIGHT button (Button A) to illuminate the screen. The backlight will remain active for 8 seconds.
