BEFORE YOU BEGIN

For best operation,

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.

HOW TO INSTALL THE TEMPERATURE SENSING CABLEG

Secure the sensor to an area you want to monitor. Do not expose it to direct sunlight.

THE RESET BUTTON

See the user’s manual of your main unit for further information.

This button is only used when the unit is operation in an unfavorable way or malfunctioning. Use a blunt stylus to hold down the button. All settings will return to their default values.

HOW TO USE THE TABLE STAND OR WALL MOUNTING

This sensor comes with a wall-mount holder and a removable stand. Use either to set up the unit.

PRECAUTIONS

This product is engineered to give you years of satisfactory service if you handle it carefully. Here are a few precautions:

1.Do not immerse the unit in water.

2.Do not clean the unit with abrasive or corrosive materials. They may scratch the plastic parts and corrode the electronic circuit.

3.Do not subject the unit to excessive force, shock, dust, temperature or humidity, which may result in malfunction, shorter electronic life span, damaged battery and distorted parts.

4.Do not tamper with the unit’s internal components. Doing so will invalidate the warranty on the unit and may cause unnecessary dam- age. The unit contains no user-serviceable parts.

5.Only use fresh batteries as specified in the user’s manual. Do not mix new and old batteries as the old ones may leak.

6.Always read the user’s manual thoroughly before operating the unit.
