INTRODUCTION

This sensor is compatible with various weather station products that carry this logo .

GETTING STARTED

The battery compartment resides in the tubular casing, and the switches for selecting channels and temperature unit are located on the inside of the main lid.

1.Twist the main lid to (unlock position), then pull it apart from the tubular casing.

2.Remove the battery compartment lid and insert 2 x UM-3 / AA 1.5V batteries, matching the polarity. Replace the battery compartment lid.

NOTE Standard Alkaline batteries contain a significant amount of water. Because of this they will freeze in low temperatures of approximately -12°C (10°F). Disposable Lithium batteries have a much lower threshold for

THWR800A_M_R0.indd 1

temperature with an estimated freezing range of below -40°C (-40°F).

IMPORTANT Do not use rechargeable batteries.

WARNING While you may use Lithium batteries to power the sensor, and although the sensor can withstand low temperatures, it is not recommended to use it in temperatures below 0°C (32°F). Placing the sensor in frozen water may damage the unit.

3.The diagram below is the inside of the main lid. Select a channel from Channel switch (1). If using more than one remote unit, select a different channel number for each unit. Select the temperature unit from °C / °F switch (2).

5.Press RESET.

USING THE SENSOR

1.The sensor has a string to loop through the hole at the base of the tubular casing. This can allow you to hang the unit while you immerse it in water.

2.Place the sensor in the water and make sure that it is within the effective transmission range (328 feet / 100 metres) from the main unit.

TIP Press RESET whenever the sensor is not performing as expected (e.g. unable to establish radio frequency link with the main unit).

TIP Place the sensor as closely as possible to the main unit. Otherwise, minimise obstructions such as doors, walls and furniture between the main unit and sensor if the sensor cannot be placed close to the main unit. You may need to experiment with various locations to get the best results.

NOTE With adequate power, the Liquid Crystal Display in outdoor temperatures will remain operational up to -28°C (-20°F).

NOTE Wireless ranges can be impacted by a variety of factors such as extremely cold temperatures. Extreme

cold may temporarily reduce the effective range between the sensor and the main unit. If the unit’s performance fails due to low temperature, the unit will resume proper functioning as the temperature rises to within the normal temperature range. No permanent damage will occur to the unit due to low temperatures.

BATTERY REPLACEMENT

Replace the batteries whenever the low battery icon shows on the remote sensor, or on the remote sensor area of the main unit. Press RESET after every battery replacement.

PRECAUTIONS

•Do not subject the unit to excessive force, shock, dust, temperature or humidity.

•Do not cover the ventilation holes with any items such as newspapers, curtains etc.

•Do not clean the unit with abrasive or corrosive materials.

•Do not tamper with the unit’s internal components. This invalidates the warranty.

•Only use fresh batteries. Do not mix new and old batteries.

•Images shown in this manual may differ from the actual display.

•When disposing of this product, ensure it is collected separately for special treatment and not as normal household waste.

•Placement of this product on certain types of wood may result in damage to its finish for which Oregon Scientific will not be responsible. Consult the furniture manufacturer's care instructions for information.

•The contents of this manual may not be reproduced without the permission of the manufacturer.

•Do not dispose old batteries as unsorted municipal waste. Collection of such waste separately for special treatment is necessary.

•Please note that some units are equipped with a battery safety strip. Remove the strip from the battery compartment before first use.

NOTE The technical specifications for this product and the contents of the user manual are subject to change without notice.

REMARQUE Les piles alcalines standard sont composées d’un volume d’eau non négligeable. Par conséquent, elles peuvent geler lors de températures inférieures à -12°C (10°F). Les piles aux lithium ont un seuil inférieur lors de températures froides, elle ne peuvent en effet geler qu’à -40°C (-40°F).

IMPORTANT Ne pas utiliser de piles rechargeables.

ATTENTION Même si vous utilisez des piles au lithium pour alimenter le capteur, et bien que le capteur puisse supporter de faibles températures, il n’est pas recommandé
