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
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).

4. Place the main lid back on the tubular casing and twist
it to (lock position).

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

• 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

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
