use with the Temperature Station

Congratulations on purchasing this optional 433MHz Outdoor Temperature Transmitter for
use with the Temperature Station. Please read the following information to ensure that this
transmitter works correctly.

Outdoor Temperature Transmitter

Features of the Outdoor Temperature Transmitter:

• Remote transmission of outdoor data to Weather Station by 433 MHz

• Shower proof casing

• Wall mountable or table standing

• Mounting at a sheltered place. Avoid direct rain and sunshine

Setting up:

Before activating the Outdoor Temperature Transmitter for use with the base receiver
Temperature Station, ensure all batteries are removed from each of the units for at least 30
seconds before proceeding with these steps:

Battery
compartment

Battery cover

Immediately after power-up, the LCD segments will light up briefly on the base receiver
Temperature Station before displaying the current indoor temperature in °C. When the
Outdoor Temperature Transmitter has transmitted data by 433MHz, it will register
accordingly on the LCD of the base receiver. For full operating instructions, please refer to
the main instruction manual for the Temperature Station.

Notes:

• Setting up should not take longer than three minutes to complete otherwise start up
problems may occur.

• When installing the batteries always check the correct polarity before inserting and
ensure the batteries do not spring free from the contacts otherwise start up problems
may occur.

• If setting up has taken over three minutes, then reset the units (see “Resetting”
below).

433MHz Signal Reception

If the outdoor temperature is not received within three minutes after setting up, the display
will show “- - - °C” on the outdoor temperature section of the receiver, please check the
following points:

1. Distance transmitters at least 2 meters away from any interfering sources such as

computer monitors or TV sets.

2. Avoid placing the temperature transmitter onto or in the immediate proximity of metal

window frames.

3. Using other electrical products such as headphones or speakers operating on the

433MHz frequency may prevent reception of the transmitted data. Interference can
also be caused by neighbours using similar electrical devices.

Affixing the Outdoor Temperature Transmitter:

The Transmitter is supplied with a holder that may be attached to a wall with the two screws
supplied. The Transmitter can also be position on a flat surface by securing the stand to the
bottom to the Transmitter. Before securing the transmitter, ensure that the 433MHz signal
(outdoor readings) is properly received.

To affix by screw, follow these
steps:

1. Using the holes in the holder
as a guide, mark the holes on
the drilling surface.

2. Drill the marked area to the
required depth.

3. Screw the holder onto wall
and click the transmitter into
holder.

The mounting surface can, however,
affect the transmission range. If for example the unit is attached to a piece of metal, it may
then either reduce or increase the transmitting range. For this reason, we recommend not

1. Insert batteries needed for the Temperature Station.

2. Unscrew the screw on the front of the compartment and
remove the cover, insert 2 x AA, IEC LR6, 1.5V batteries into
the battery compartment. Replace the battery cover on the unit
and seal by re-screwing.

3. If you have purchased additional outdoor transmitter(s),
ensure that you leave 10 seconds for the signal reception of the
first transmitter before setting up the following transmitter; i.e.
the first transmitter will have the temperature displayed with the
number 1 against it and so on.

4. Repeat step 2 - 3 for each additional Outdoor
Temperature Transmitter.

5. Position the Outdoor Temperature Transmitter in the
desired locations (see Affixing the Outdoor Temperature

Transmitter).

• Do not submerge any of the units in water or use them in any way other than what

• Remove all low powered batteries immediately to avoid leakage and damage.

• Do not make any repairs to the units. Return to the original point of purchase for
