BEFORE YOU BEGIN

For best operation,

NOTE ON COMPLIANCE

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operations. Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. FCC : NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: orient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer of an experienced radio/TV technician for help.

1. Assign different channels to different remote units. 2. Insert batteries for remote units before doing so for the main unit. ( Main unit of models listed under optional items ) 3. Place the main unit as close as possible next to the remote unit, reset the main unit after installing batteries. This will ensure easier synchronization between the transmission and reception of signals. 4. Position the remote unit and main unit within effective transmission range, which, in usual circumstances, is 20 to 30 meters(upto 100 feet). Note that the effective range is vastly affected by the building materials and where the main and remote units are positioned. Try various setups for best result. Though the sensor is weather proof and meant to be used outdoors, it should be placed away from direct sunlight, rain or snow.
BATTERY AND CHANNEL INSTALLATION
The remote unit uses two AA-size batteries. To install them, 1. Remove the screws on the battery compartment. 2. Select the channel number on the CHANNEL slide switch. 3. Select the temperature display unit on the C/F slide switch. 4. Insert the batteries strictly according to the polarities shown inside. 5. Replace the battery compartment door and secure its screws.

CHANGE CHANNEL

Once a channel is assigned to a unit, you can only change it by removing the batteries and repeating the above procedure.

LOW-BATTERY WARNING

Replace the batteries of the sensor when the low-battery indicator of the channel represented by the sensor shows up on the main unit.

OPERATION

Once batteries are in place, the sensor will start transmitting samplings at 40-second intervals. The current temperature will be shown on the LCD in the selected unit ( C/F ) at the designated channel. The unit ( C/F ) shown on the main unit is determined by the setting on the main unit.
