HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE STATION

The Temperature Station uses 3 x AA, IEC LR6, 1.5V batteries. To install and replace the batteries, please
follow the steps below:

HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE
TRANSMITTER

The Outdoor Temperature transmitter uses 2 x AAA. IEC LR03, 1.5V batteries. To install and replace the
batteries, please follow the steps below:

Battery compartment

1. Insert finger or other solid object in the space at the bottom
center of the battery compartment and lift up to remove the
cover.

2. Insert batteries observing the correct polarity (see marking).

3. Replace compartment cover.

1. Remove the battery cover

2. Insert the batteries, observing the correct
polarity (see battery compartment marking)

3. Replace the battery cover on the unit

BATTERY CHANGE:

User shall replace batteries of the temperature station when the battery low indicator is displayed at the
LCD. If user does not replace batteries, working error may be resulted.

Note:

• After changing batteries in temperature station, there is no need for user to reset the temperature

station. In fact, the temperature station can remember all transmitter information and sequence as
per the pervious set-up. However, user may require to reset the desired LCD contrast, Alarm On/Off
condition and the Clock (by re-entering the date and time manually or simply wait for the DCF time
signal).

• The “Average” value display for particular channel will only be calculated from the data after battery

change.

• User needs to carry out the re-learning of the particular transmitter after replacing batteries to it. See

“LEARNING/ REMOVING A TRANSMITTER (CHANNEL)” for the procedures of relearning a
transmitter.

• It is recommended to replace the batteries in all units on an annual basis to ensure optimum

accuracy of these units.

Please participate in the preservation of the environment. Return used batteries to an
authorized depot.

SETTING UP

1. Insert batteries into the Temperature station (see “How to install and replace batteries in the
Temperature” above). Once the batteries are in place, all segments of the LCD will light up briefly.

Then the indoor temperature and humidity will be displayed. The time will be shown 0:00 and the
date as 1.1.04.

Note:
If the indoor temperature and humidity are not displayed after 15 seconds, remove the batteries and wait
for at least 2 minutes before reinserting them. Also check if the battery has been used up. User is
recommended to use new alkaline batteries to the units.
There is a four-minute time for user to set up all transmitters one by one, after inserting batteries to the
temperature station. The below steps 2 to 4 shall be completed within this 4-minute time.

2. Insert batteries to the first transmitter. The temperature station will start learning the transmitter. The
outdoor Channel 1 (out 1) temperature and humidity readings will then be displayed. User may
observe the outdoor channel icon appear. (If this does not happen after 3 minutes, the batteries will
need to be removed from both units and reset from step 1.)

3. After the readings from the first transmitter (Channel 1) are successfully shown by the temperature
station, insert batteries to the second transmitter. The outdoor “Channel 2” temperature and
humidity readings will then be displayed. User may observe the outdoor channel icon appear.

4. Set up the third as described in the above steps.

5. The temperature station will also try to receive the DCF time signal (radio controlled) after the
transmitter signal reception.

6. If after 10 minutes, the DCF time has not been received, press and hold the SET key for 3 seconds
to enter the Set up mode for manual time setting. The clock of the temperature station will
automatically attempt to receive the DCF time at midnight. When this is successful, the received
time will override the manually set time. The date is also updated with the received time. (Please
refer also to notes on “Radio controlled Time Reception” and “Manual Setting”).

DCF-77 RADIO CONTROLLED TIME

The time base for the radio controlled time is a Cesium Atomic Clock operated by the Physikalisch
Technische Bundesanstalt Braunschweig which has a time deviation of less than one second in one million
years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77
(77.5 kHz) and has a transmitting range of approximately 1,500 km. Your radio-controlled Temperature
Station receives this signal and converts it to show the precise time in summer or wintertime.
The quality of the reception depends greatly on the geographic location. In normal cases, there should be
no reception problems within a 1500km radius of Frankfurt.
Once the outdoor reception test period is completed, the DCF tower icon in the clock display will start
flashing in the upper center. This indicates that the clock has detected that there is a radio signal present
and is trying to receive it. When the time code is received, the DCF tower becomes permanently lit and the
time will be displayed.
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, then please
take note of the following:

• Recommended distance to any interfering sources like computer monitors or TV sets is a minimum

of 1.5 - 2 meters.

• Within ferro-concrete rooms (basements, superstructures), the received signal is naturally

weakened. In extreme cases, please place the unit close to a window and/ or point its front or back
towards the Frankfurt transmitter.

• During nighttime, the atmospheric disturbances are usually less severe and reception is possible in

most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.
