SET UP

Install or Replace Batteries
Batteries must be installed for the main monitor and remote sensor to work.

Main monitor

1. Slide off the battery cover of the main monitor.
2. Insert 2x AAA batteries and ensure that poles [“+”and “-“] are correct.
3. Close battery cover.
4. Main monitor will automatically start in normal mode.

Wireless remote sensor

1. Slide off battery cover from wireless remote sensor.
2. Insert 2xAA batteries and ensure that poles [“+”and “-“] are correct.
3. Select channel through the “l 2 3” knobs for wireless remote sensor.
4. The indicator will light up once to indicate that the detected temperature and humidity have been transmitted by wireless remote sensor.
5. Close battery compartment.

Synchronize remote sensors with main monitor

1. Place the remote sensor near main monitor.
2. Once batteries are installed in main monitor, the RF signal icon 1ocated on the upper left side of the display will flash for 3 minutes. This indicates that the main unit is in synchronization mode and waiting for the remote sensor to connect.
3. If the RF signal icon stops flashing after 3 minutes, press and hold “-/CH” button for 2 seconds until the RF signal flashing again to set the main unit back in synchronization mode.
4. Press” -/CH” button on the main monitor to select CHl, CH2, CH3, or CHl- CH3 (auto-alternating display from CHl to CH3 every 5 seconds with icon C displaying on the upper left side of the display).

5. Install batteries for the remote sensor and select channel with numbered knobs (1, 2, and 3) to select CHl, CH2, or CH3.
6. Ensure that main monitor and remote sensor are on the same channel. When the main monitor successfully receives signals from remote sensor, the temperature and humidity detected by the remote sensor will show on the main monitor LCD display.
7. The main monitor can connect up to 3 remote sensors at the same time. If multiple sensors are used simultaneously, please repeat above steps after installing batteries to connect other remote sensors, make sure these sensors on different channels. Press ” -/CH” button on the main monitor to view the readings of each channel.
8. If the main monitor fails to synchronize with the remote sensor on any channel. Adjust the main monitor to the corresponding channel, press and hold “-/CH” button for 2 seconds to search signals for the remote sensor. Press “TX” button inside the battery bay of the corresponding remote sensor to send out signals manually.

Toggle Fahrenheit or Celsius

To select Fahrenheit or Celsius, press “°C/° F ” button located on the back of the monitor.

Placement for Maximum Accuracy

The main monitor is equipped with a high-performance sensor. Because this device is sensitive to surrounding environment conditions, it is important to place the monitor in an ideal spot for the most accurate readings. Place the monitor in a dry area free of dirt and dust, out of direct sunlight, and away from heats sources or vents. To ensure accurate humidity measurement, place monitor away from humidity sources. The wireless remote sensor is not waterproof and should also avoid prolonged contact with direct sunlight. You can place it under a covering to avoid both rain and sun.

USING YOUR DEVICE

Maximum and Minimum Records

The SC92 displays maximum and minimum records for both temperature and humidity.
“24hr” refers to maximum and minimum readings from the last 24 hours.
“All-time” refers to maximum and minimum readings since batteries were installed.
Press “+/MEM” button in normal mode to enter 24hr or All-time mode.
Press “-/CH” button to choose the channel to display on the monitor.

Options: CHl, CH2, CH3, and CH1-CH3 (auto-alternating display from CHl to CH3 every 5 seconds).
