SETTING UP:
Note: this temperature station can only receive one transmitter only.
1. First, insert the batteries to the transmitter (see “How to install and
replace batteries in the Temperature transmitter” below).
2. Within 30 seconds of powering up the transmitter, insert the
x Remote transmission of outdoor temperature

x Wall mounting and table-standing
x Mounting at a sheltered place. Avoid

batteries to the Temperature Station (see “How to install and
replace batteries in the Temperature station” below). Once the
batteries are in place, all segments of the LCD will light up briefly.
Following the indoor temperature, the time as 12:00 will be
displayed. If they are not shown in LCD after 60 seconds, remove
the batteries and wait for at least 60 seconds before reinserting
them. Once the indoor data is displayed user may proceed to the
next step.
3. After the batteries are inserted, the Temperature Station will start
receiving data signal from the transmitter. The outdoor temperature
should then be displayed on the Temperature station. If this does
not happen after 2 minutes, the batteries will need to be removed
from both units and reset from step 1.
4. In order to ensure sufficient 915 MHz transmission however, this
should under good conditions be a distance no more than 200 feet
6
(60 meters) between the final position of the Temperature Station
and the transmitter (see notes on “Positioning” and “915 MHz
Reception”).
HOW TO INSTALL AND REPLACE BATTERIES IN THE
TEMPERATURE STATION
The Temperature Station uses 2 x AAA, IEC LR3, 1.5V batteries. When
batteries will need to be replaced, the low
battery icon will appear on the LCD. To
install and replace the batteries, please
follow the steps below:
1. Lift up the battery compartment cover.
2. Insert batteries observing the correct
polarity (see marking).
3. Replace compartment cover.

BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure
optimum accuracy of these units. (Battery life –see Specifications)
Please participate in the preservation of the environment.
Return used batteries to an authorized depot.

TO RESET THE MIN/MAX DATA:
The MIN/MAX temperature can be reset manually by pressing and holding
the + key for about 3 seconds. This will reset all indoor and outdoor
MIN/MAX temperature to current indoor and outdoor temperatures.
915 MHz RECEPTION CHECK
The Temperature Station should receive the outdoor temperature data
within a few minutes after setup. If the temperature data are not received
about 2 minutes after setup (the signal reception icon does not appear),
please check the following points:
1. The distance of the Temperature Station or transmitter should be at
least 5 to 6.5 feet (1.5 to 2 meters) away from any interfering
sources such as computer monitors or TV sets.
2. Avoid positioning the Temperature Station onto or in the immediate
proximity of metal window frames.
3. Using other electrical products such as headphones or speakers
17
operating on the same signal frequency (915MHz) may prevent
correct signal transmission and reception.
4. Neighbors using electrical devices operating on the 915MHz signal
frequency can also cause interference.
Note:
When the 915MHz signal is received correctly, do not re-open the battery
cover of either the transmitter or the Temperature Station, as the batteries
may spring free from the contacts and force a false reset. If this happens
accidentally, all units must be reset (see Setting up above) otherwise
transmission problems may occur.
The transmission range is about 200 feet / 60 m from the transmitter to the
Temperature Station (in open space). However, this depends on the
surrounding environment and interference levels. If no reception is
possible despite the observation of these factors, all system units have to
be reset (see Setting up above).
18
POSITIONING THE TEMPERATURE STATION:
The Temperature Station comes attached with a
table stand, which provides the option of table
standing the unit in addition to wall mounting.
19
20
To wall mount:
Before wall mounting, please check that the outdoor
temperature values can be received from the desired
locations:
1. Fix a screw (not supplied) into the desired wall,
leaving the head extended out by about 5mm.
2. Hang the Temperature Station onto the screw.
Remember to ensure that it locks into place before
releasing.
POSITIONING THE REMOTE TEMPERATURE TRANSMITTER:
The remote temperature transmitter can be placed onto any
flat surface or wall mounted using the bracket which doubles
as a stand or wall mount base.
To wall mount:
range. For this reason, we recommend not to place the unit on any metal
surfaces or in any position where a large metal or highly polished surface
is in the immediate vicinity (garage doors, double glazing, etc.). Before
securing in place, please ensure that the Temperature Station can receive
the 915MHz signal from the temperature transmitter at the positions that
you wish to place them.
1. Secure the bracket onto a desired wall using the
screws and plastic anchors.
2. Clip the remote temperature transmitter onto the
bracket.
Note:
The mounting surface can affect the transmission range.
If, for instance, the unit is attached to a piece of metal, it
may then either reduce or increase the transmitting
21
CARE AND MAINTENANCE:
x Extreme temperatures, vibrations and shocks should be avoided as
these may cause damage to the unit and give inaccurate forecasts
and readings.
x When cleaning the display and casings, use a soft damp cloth only.
Do not use solvents or scouring agents as they may mark the LCD
and casings.
x Do not submerge the units in water. Furthermore, fix all parts in
place where the units are adequately protected against moisture
and rain.
x Immediately remove all low powered batteries to avoid leakage and
damage. Replace only with new batteries of the recommended
type.
x Do not make any repair attempts to the unit. Return them to their
original point of purchase for repair by a qualified engineer.
22
Opening and tampering with the unit may invalidate their
guarantee.
x Do not expose the units to extreme and sudden temperature
changes, this may lead to rapid changes in forecasts and readings
and thereby reduce their accuracy.
