RCC (Radio Controlled Clock) Receiving Mode

1. During the RF receiving mode, if any key is pressed or time out (3minute), the
unit will enter the RCC receiving mode(maximum 8 minutes). Press any key to
exit the RCC receiving mode.
2. If no RCC signal is detected, the base station will try once every hour to get
an RCC signal until a signal is received. Once the base station receives the
RCC signal it will overwrite the manually set time and date, on the base station
the RCC tower icon will be display.
3. If RCC signal is detected successfully, the base station will continue to scan
for the RCC signal each day at 2:00, 8:00, 14:00 and 20:00, despite if you
manually set the date and time.
4. The best condition for reception is at night, between midnight and 6:00am –
when there is less atmospheric interference.

After both outdoor temperature and radio controlled time are displayed you can
place your remote sensor outdoors at the final destination.

Note for Radio Controlled Time:

The DCF WWVB or MSF time signal is an AM modulated time-of-day signal
broadcasted by the Federal Government of Germany, NIST from USA or
National Physical Laboratory. The time base is generated from an atomic
time generator which is accurate to 10 billions of one second.

Please take note of the following for RCC time reception:

z

Recommended distance to any interfering sources like computer monitors

or TV sets is a minimum of 1.5-2 meters.

z

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.

2.3 Additional transmitters

The wireless weather station can receive up to 3 temperature sensors. If you
have purchased additional remote sensors, repeat step 1) for all extra sensors.
However, ensure that you

leave 10 seconds in between the reception of the

last sensor and the set-up of the following sensor

. The wireless weather

station will number the sensors in the order of set-up automatically, i.e. the first
temperature sensor will have the temperature displayed with

1.

If only have one

sensor,

1

won’t be display.

2.4 Mounting

2.4.1 Base Station

With one foldable leg at the back of the unit, the base station can be placed onto
any flat surface or wall mounted at the desired location by the hanging holes at
the back of the unit. It is important to check that the radio signal can be received
before permanently mounting any of the units

2.4.2 Remote Sensor

Note:

To achieve a true temperature reading, avoid mounting remote sensor in
