Installing or Replacing Batteries
Geevon recommends using high-quality batteries for optimal product performance. Heavy-duty or rechargeable batteries are not recommended. The outdoor sensor requires lithium batteries in low-temperature conditions, as cold temperatures can cause alkaline batteries to function improperly. Do not mix old and new batteries, nor alkaline, standard, and/or rechargeable batteries.
Default Settings
- Default time: 12:00 (US) / 0:00 (EU)
- Default date: 01/01 (Year: 2020), date format: M/D (US) / D/M (EU)
- Default temperature: °F (US) / °C (EU)
- Default alarm: AM 6:00, default snooze time: 5 minutes.
The LCD display will fully illuminate for 3 seconds when changing new batteries or resetting, then emit a sound ("Bl") before returning to normal state. After testing temperature, it will receive RF signals for 3 minutes.
Manually Setting the Time, Date & Units
To set the time, date, and units:
- Press and hold the "SET" button for 3 seconds. The 12/24 hour mode will flash. Use "UP" and "DOWN" buttons to set the correct mode.

- Indoor and outdoor humidity range: 20%-95%.
- When the alarm is ringing, temperature and humidity testing will be stopped.
Accuracy
- Temperature accuracy:
- -40°C to -20°C: ± 4°C
- -20°C to 0°C: ± 2°C
- 0°C to +50°C: ± 1°C
Note: When the temperature is in the 50°C to 70°C range, the temperature is only for reference.

- ± 10% RH (@25°C, 20%RH to 29%RH, 51%RH to 95%RH)
Backlight
Press the SNZ / LIGHT button to activate the backlight for 5 seconds.
Low Battery Indicator
If the low battery indicator is displayed on the LCD for either the outdoor sensor or the display unit, Geevon recommends immediately changing the batteries to prevent disruptions in communications between the devices.
Setting the Channel
To set the channel connection between the display unit and outdoor sensor:
- To change the channel on the display unit between 1, 2, 3, and 1-3 sequential display, press the "CH" button. The channel setting will display above the outdoor temperature.
- To change the channel option on the outdoor sensor, open the battery compartment cover. A button is located on the upper left side.
- Always ensure the channel chosen on the display unit matches the channel option chosen on the outdoor sensor.
Placement of the Device
Proper placement of both the display unit and the outdoor sensor is critical to the accuracy and performance of this product.
Display Unit Placement
Place the display unit in a dry area free of dirt and dust. The display unit stands upright for tabletop/countertop use.
Important Placement Guidelines
- To ensure accurate temperature measurement, place units out of direct sunlight and away from any heat sources or vents.
- The display unit and outdoor sensor must be within 200 feet (60 meters) of each other.
- To maximize wireless range, place units away from large metallic items, thick walls, metal surfaces, or other objects that may limit wireless communication.
- To prevent wireless interference, place both units at least 3 feet (1 meter) away from electronic devices (e.g., TV, computer, microwave, radio).
Diagram Description: A visual representation shows the main display unit and the outdoor sensor. An arrow indicates a maximum distance of 200 feet (60 meters) between them. Another diagram shows the main unit placed at least 3 feet (1 meter) away from electronic devices like a TV, computer, microwave, or radio, emphasizing the need for separation to avoid interference.
Outdoor Sensor Placement
- The sensor must be placed outside to observe outdoor conditions. It is water resistant and designed for general outdoor use; however, to prevent damage, place the sensor in an area protected from direct weather elements and direct sunshine. The best location is 4 to 8 feet above the ground with permanent shade and plenty of fresh air to circulate around the sensor.
- The display unit and outdoor sensor must be within 100 feet of each other.
- To maximize the wireless range, place units away from large metallic items, thick walls, metal surfaces or other objects that may limit wireless communications.
- To prevent wireless interferences, place both units at least 3 feet away from electronic devices (e.g., TV, computer, microwave).
Outdoor Sensor Function
- Once the display unit has been set up and the channel synchronized with the outdoor sensor, the display unit will begin the registration process. This can take up to 3 minutes to complete, during which the display unit will search for an RF (Radio Frequency) signal from the outdoor sensor. The outdoor sensor signal strength will show the connection strength. If there are no bars or if bars are not showing at maximum strength (4 bars), try placing the outdoor sensor or display unit elsewhere for better connection.
- If the RF Signal is lost and not reconnected, the outdoor temperature and humidity level will begin to flash after 1 hour of lost connection. If no connection is found after 2 hours, a dotted line "---" will be displayed in place of the temperature and humidity level.
- To manually restart the RF registration, press and hold the "CH" button for 3 seconds. The display unit will now search for the RF signal for the next 3 minutes.

|---|
| Inaccurate Temperature/Humidity | - Ensure both the main unit and sensor are placed out of direct sunlight and away from any heat sources or vents.
- Do not tamper with the internal components.
- Temperature accuracy:
- -40°C to -20°C: ± 4°C
- -20°C to 0°C: ± 2°C
- 0°C to +50°C: ± 1°C
- Humidity accuracy:
- ± 5% RH (@25°C, 30%RH to 50%RH)

|
| Alarm clock couldn't stop | - Press any button (except the SNZ/LIGHT button) to stop the alarm. Otherwise, it will stop automatically after 2 minutes.
- While the alarm signal is sounding, press the SNZ/LIGHT button to activate the snooze function. The alarm will sound after 5 minutes.
|
| Outdoor reading is flashing or showing dashes | Flashing of the outdoor reading generally indicates wireless interference. This thermometer is arranged to communicate with three external sensors. One comes with the unit, the remaining two are optional. - Bring both the sensor and display indoors, side by side, and remove batteries from each. Power the thermometer as described in "Getting started."
- Set the selector in the outdoor sensor to the desired transmission channel (1, 2, or 3). Automatic data will be transmitted.
- Press the CH button multiple times to select the channel set on the external sensor. Sequentially select channel 1, channel 2, channel 3, and sequentially display for 3 channels.
|
| No outdoor sensor reception | - Reload the batteries of both outdoor sensor and main unit. Refer to the "SENSOR SETUP" section.
- Press and hold the CH button to receive RF signal.
- Always ensure the channel chosen on the display unit matches the channel option chosen on the outdoor sensor.
- Relocate the main unit and/or the outdoor sensor. The units must be within 150 feet (50 meters) of each other.
- Ensure both units are placed at least 3 feet (1 meter) away from electronics that may interfere with wireless communication (such as TV, microwave, computer, radio, etc.).
- Do not use heavy-duty or rechargeable batteries. The outdoor sensor requires lithium batteries in low temperature conditions. Cold temperatures would cause alkaline batteries to work improperly.
- Do not mix old and new batteries.
|
| "HH/LL" display in indoor and/or outdoor temperature | If the temperature is higher than the detection range, "HH" will display on screen; if lower than the detection range, "LL" will display on screen. |
| Backlight doesn't work | Press the SNZ / LIGHT button to activate the backlight for 5 seconds. |
| Care and maintenance | - To maximize wireless range, place units away from large metallic items, thick walls, metal surfaces, or other objects that may limit wireless communication.
- Immediately change the batteries if the low battery indicator is displayed on the LCD for the sensor.
- Do not clean any part of the product with benzene, thinner, or other solvent chemicals. When necessary, clean it with a soft cloth.
- Never immerse the product in water. This will damage the product.
- Do not subject the product to extreme force, shock, or fluctuations in temperature.
