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.
