Then insert the DC jack to the back case of your unit. Take out the stand at the back case and insert it horizontally to the back case, then rotate it by 90 degree to secure it to the back case. Step 2: install batteries to your outdoor transmitter Keep your weather station and wireless outdoor transmitter next to each other. Slide open the battery cover at the back of your wireless outdoor transmitter, then insert 2 x AAA alkaline batteries to the battery compartment. Make sure the Channel selector is at 1 position. Replace the battery cover. Remark : Make sure (Channel 1) is displayed under the outdoor temperature and humidity. You could press  / CHANNEL to select Channel 1. Your weather station will receive data signal from the outdoor transmitter in few seconds. Then place your outdoor transmitter in a dry and shaded area. P. 3 Installing backup batteries to your weather station Your weather station requires 3 “AAA” alkaline batteries to provide backup power to it in the event of a temporary power interruption. 1. Place your unit face down on a flat surface. 2. Slide and remove the battery cover at the bottom of your unit. 3. Insert 3 “AAA” alkaline batteries into the battery compartment by observing the “+” and “-“ polarity as indicated. 4. Replace the battery cover. If the AC main power is interrupted, the backlight will go off. The backup batteries will keep the time and all settings of your unit. Press once to turn on the backlight for 5 seconds. Remarks: Keep in mind that your outdoor transmitter has a 180-ft open air transmission with no obstructions. Actual transmission range will vary depending on what is in the path of the signal. Each obstruction (roof, walls, floors, ceilings, thick trees, etc.) will effectively cut signal range in half. Insert the holder to the bottom of the outdoor transmitter for desktop or insert it to the back of the transmitter for wall mount purpose.
