CHANNEL SLIDE SWITCH Designates the remote unit Channel 1, Channel 2 or Channel 3 C. [. . . ] Set the main and remote units within range (20 to 30 meters). · · Try different set-ups for best transmission and reception. Position the remote units away from direct sunlight, rain or snow. BATTERY INSTALLATION: MAIN UNIT 1. Insert two AA-sized batteries. BATTERY AND CHANNEL INSTALLATION: REMOTE UNIT 1. Install 2 alkaline batteries (UM-4 or "AAA" size 1. 5V) strictly according to the polarities shown. Note that once a channel is assigned to a remote unit, you can only change it by removing the batteries or resetting the unit. Replace the battery compartment door. GB GB GETTING STARTED Once batteries are in place for the remote units, they will start transmitting samplings roughly at 30-second intervals. The temperature of the selected channel will be displayed on the main display and the indoor temperature on the secondary display. The main unit will automatically update its readings at 30-second intervals. The battery level of the main unit will be shown on the indoor temperature when it is running low. 5 GB GB Remote unit Wall-mount Velcro ® tape PRECAUTIONS This unit is engineered to give you years of satisfactory service if handled carefully. Do not subject the unit to snow or excessive force, shock, dust, temperature or humidity.
