Thank you for purchasing the Kelvin Duo wine thermometer. When
developing this product our goal was to provide a meaningful and easy way
to understand dierent wine serving temperatures.
It’s a common generalization that red wine should be served at room
temperature and white wine should be served from the refrigerator. The
reality is that the ambient room temperature of most homes is higher than
the recommended serving temperature for red wine, and most refrigerators
are signicantly colder than the recommended serving temperature for many
white wines.
The Kelvin Duo provides an easy to use reference point that will guide wine
drinkers towards the optimum serving temperatures for dierent types of
wines. Using three words on the LCD display; ‘Under, Ideal and Over’ and
using LED backlight indication colours; ‘Blue, Green and Red’ makes it easy
to see when a wine has reached the optimum serving temperature. We hope
that the Kelvin Duo wine thermometer will provide you with years of trouble
free service, and will help you develop your appreciation of wine by serving
it at its optimum temperature.
Your product is covered by a 24 month manufacturer’s warranty.

Best practice
Ensure the clip is always rmly registered against the
exterior of the glass bottle, do not place the clip against
a label.
Ensure the clip is always below the level of the wine
inside the bottle.
When placing or removing the bottle from the
refrigerator there maybe a sudden dierence in
the temperature reading. This is due to the ambient
temperature change on all surfaces including the
internal components of the transmitter clip.
This may take up to 10-15 minutes to normalize after
which a predictable steady temperature change will be
observed.
When chilling the wine we suggest allowing the
temperature to drop below the ideal target zone until the
backlight turns ‘blue’ and displays the word ‘Under’.
Remove the wine from the refrigerator, this will then
provide the longest possible drinking time as the
temperature starts to rise again and the backlight turns “green’ and displays
the word ‘Ideal”. When the backlight turns ‘red’ and displays the word ‘Over’
place the wine back in the refrigerator to repeat the process.
Precautions
Do not fully submerge the transmitter clip in water, although a rubber plug
is provided for sockets, this is splash resistant only and not fully waterproof.
Do not submerge the receiver base in water.
Do not expose the clip or receiver parts to extreme sunlight or humidity
Remove batteries from the receiver base if the product is not going to be
used for long periods of time.
Do not dismantle the receiver base or clip components; the unit does not
contain user serviceable components.

Battery installation
It is necessary to t 3x AAA batteries
(not supplied) into the receiver base.
Turn the receiver base over to reveal
the base plate of the product.
Using a suitable screwdriver carefully
remove the 4 securing screws from
the base plate putting them to one side.
Take care not to loose these screws.
Carefully remove the base plate from
the product to expose the battery
compartment.
Observe the correct polarity of the 3
battery positions, carefully insert the
batteries pushing the ‘-‘ end of the battery
in at an angle against the spring rst, then
push the battery downwards to connect the
‘+’ end to the contact accordingly.
Repeat this process for the other 2
batteries.
Carefully replace the base plate ensuring
the 4 screw holes and power switch hole
are aligned correctly.
Replace the 4 screws and tighten,
do not over tighten.

5
Using the product
Turning the power on
It is necessary for both the clip and the
receiver base to be turned on.
Turn on the receiver base:
Turn the receiver base over.
Use the slide switch to turn on the power
Either push the switch to the left for Fahrenheit operation, or to the right for
Celsius operation. The LCD display on the front of the unit will display
characters when the power is applied.
OFF °F°C
Turn on the transmitter clip:
The power switch is located on the side of the
clip adjacent to the USB charger socket.
Depress the rubber switch once to turn
the power on. The LED light will illuminate for
1 second to indicate the power is on, it will
then ash every 1 minute to indicate the clip is
operational.
Depress and hold the power switch again to turn o the power.
The LED will illuminate for 3 seconds before powering o completely.
Transmitter clip and receiver base pairing
The transmitter clip and base receiver will pair automatically; this may take
up to 1 minute. If during use the display suddenly reads ‘00’ then this is an
indication that the receiver base has lost the transmitting signal from the clip.
Please check the clip is working and ensure the receiver base is within a
suitable working distance from the transmitter clip (10m). The transmitter will
work from within a closed refrigerator, however the workable range may be
aected.
When the clip is working, by depressing the power button momentarily this
will force data to be transmitted to the receiver base. This may be useful if
the transmission has been lost and you wish to test the connection.
If the clip and receiver seem unresponsive, please refer to the trouble
shooting guide on page 11 for advice on how to reset pairing.

Colour sticker identication
The product is supplied with a sheet of
24 coloured stickers (2 x 12 dierent
colours). The purpose of these is to
provide two corresponding coloured
stickers which can be placed on both
the transmitter clip and receiver base
to allow quick identication when
using more than one Kelvin Duo
in close proximity.
Remove the stickers from the sheet and
place them carefully on the recessed areas
provided within the tooling mouldings.
Selecting your wine
The Kelvin Duo has been pre-programmed with 10 dierent wine types,
each has its optimum serving temperature stored:
Wine Type Optimum Target Temp. (ºC / ºF) Suggested Ideal Range (ºC / ºF)
Light white wine 7 / 45 5-8 / 41-47
Medium white wine 10 / 50 8-11 / 46-52
Full white wine 12 / 53 10-13 / 50-53
Dessert wine 8 / 46 6-9 / 42-48
Light red wine 11 / 52 9-12 / 48-54
Medium red wine 15 / 59 13-16 / 55-61
Full red wine 17 / 63 15-18 / 59-65
Vintage sparkling 9 / 48 7-10 / 41-47
General sparkling 7 / 45 5-8 / 44-50
Rose 7 / 45 5-8 / 41-47
It is necessary to select the correct wine type for the wine you wish to
measure. If you are not sure which type of wine you are drinking we have
provided a comprehensive list of wine varieties on the inside cover of the
retail box. This list contains over 100 of the most popular wine varieties.

7
We have also provided a colour reference chart which will give you an
indication as to the type of wine based on its colour. If you are still unsure as
to the type of wine you are drinking please refer to the wine producer who
will be able to clarify this for you.
Use the wine button to select the wine type you are measuring.
The LCD segment adjacent to the wine will be illuminated to denote the wine
type chosen, the target temperature for the wine type will also change as
dierent wine types are selected.
Pressing the wine button repeatedly will
advance the wine selection in a clockwise
fashion; the LCD segment will ash for a
period of 5 seconds after which the wine
type will be selected.
The wine button can be pressed again
after the selection has been made, the LCD
segment will ash in the current selection,
press the wine button again to advance, or
leave for 5 seconds for the current selection
to be conrmed.
Making a manual adjustment to the target temperature
It is possible to alter the pre-programmed target temperature to suit your
own preference.
During the wine selection process when the LCD segment is ashing it is
possible to alter the target temperature of the wine.
If the LCD segment is not ashing it is not
possible to alter the target temperature,
this avoids any inadvertent alteration of the
target temperature during normal operation.
If necessary press the wine button to invoke
the LCD segment to ash.
Using the ‘+’ & ‘-‘ keys adjust the target
temperature to your desired setting.
After the LCD segment has stopped
ashing the new target temperature
will be used.

Storing your preferences
The Kelvin Duo has the ability to store the settings for 3 of your favourite
wine types, saving you time if you drink a particular wine type frequently. It
will also allow you to store any manual adjustments made to temperature
for quick recall.
Once you have selected the wine you are
drinking and made any personal temperature
adjustments, whilst the display is still ashing,
hold down the memory button you wish to use
(1,2 or 3) until the LCD display has stopped
ashing.
This wine type and any adjustments made will
be stored and can be recalled at any time by
simply pressing this memory button.
Placing the transmitter clip on the bottle
It is necessary to place the transmitter clip
onto the bottle against the exterior glass.
The Kelvin Duo transmitter clip is tted with
a conductive heat transfer pad that ensures
a good surface contact with the bottle and
improved heat transfer characteristics.
Ensure the clip is placed onto the glass
below the level of the wine in the bottle.
It maybe necessary to move the clip down
periodically as the wine is consumed.
It is suggested that the clip is completely
removed and repositioned rather than trying
to slide the clip down the bottle as this may
damage the heat transfer pad.
Push the open section of the clip against the bottle.
This will widen the aperture allowing the clip to pass onto the bottle.
Ensure the heat transfer pad is sitting rmly and squarely against the bottle.
Ensure the power switch on the clip is activated as described on page 5.

9
Clip charging process
The thermometer transmitter clip has been tted with a rechargeable
battery to avoid having to repeatedly open the sealed back plate; it also
reduces the overall running cost of the unit by not having to replace
batteries periodically.
Use the USB charging lead supplied and plug the large USB lead into a
suitable USB power supply (PC, laptop, USB PSU).
Remove the rubber plug on the side of the clip to expose the USB socket.
Plug the small end of the USB cable into the USB socket on the side of the
clip. The clip will start charging immediately.
The LED indicator will be illuminated permanently to indicate the charging
sequence is underway. When the battery charging cycle is complete the
LED will turn o.
Remove the USB lead from USB sockets in the clip and the charging unit.
Replace the rubber plug back into the USB socket on the side of the clip.
When the battery power within the clip has become low, the LED will ash
every 2 seconds to indicate that recharging is required.
Ensure the power is turned o after use to conserve the battery life.

10
Receiving information on the receiver base
The clip will start to transmit data immediately after power up, ensure the
receiver base is also switched on as detailed on page 5 to receive
temperature data.
Based on your previous wine selection the target temperature will be shown
at the top of the LCD screen.
The current bottle temperature will be shown as large numerals in the centre
of the LCD display.
The status will be shown below the temperature display as a word:
Under - the temperature is below the target zone.
Ideal - the temperature is within the target zone.
Over - the temperature is above the target zone.
The backlight LED will pulse to indicate the temperature status;
Blue - the temperature is below the target zone.
Green - the temperature is within the target zone.
Red - the temperature is above the target zone.
The temperature data will be updated on average every 60 seconds.
