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 10°F (-12°C). Disposable Lithium
batteries have a much lower threshold for
temperature with an estimated freezing range
of below -40°F (-40°C).
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
32°F (0°C). 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 -20°F (-28°C).
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

• 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.
