NOTE:
1.Avoid pressing any buttons on the main unit before the remote temperature is displayed for about 2 minutes.
2.The effective operating range may be influenced by the surrounding building materials and how the receiver and transmitter are positioned.
3.Place the remote sensor so that it faces the main unit (receiver), minimizing obstructions such as doors, walls, and furniture.
4.Though the remote sensors are
NOTE: When the temperature falls below freezing, the batteries in the outdoor remote sensor may have reduced voltage supply and a shorter effective range. We recommend using lithium batteries at temperatures of 32°F (0°C) and below.
BATTERY INSTALLATION

GETTING STARTED
After batteries are installed; remote sensor will transmit temperature readings at 45 second intervals. The main unit may take up to two minutes to receive the initial readings. Upon successful reception, remote temperature will appear on the larger section of the main unit’s display (the default remote channel is channel one). The main unit will automatically update readings at
If no signal is received from the remote sensor within two minutes, dashes [- -
CHECKING REMOTE AND INDOOR TEMPERATURE AND HUMIDITY
The default display shows the indoor temperature and humidity information (temperature is on the top, and humidity is on the bottom line).The IN icon indicates that the unit is displaying the indoor readings.
