Inserting The Batteries - Clas Ohlson WH-1080 User Manual

Inserting the batteries
Transmitter/Outdoor unit
Insert 2 x alkaline LR6/AA batteries into the transmitter (making sure all the batteries are correctly inserted
according to the markings in the battery compartment). The indicator on the front of the unit is lit for
approximately 4 sec. before it goes out and the unit begins functioning normally.
Receiver/Indoor unit
1. Open the battery compartment on the back of the unit and insert 3 x alkaline LR6/AA batteries. Make sure
to insert the batteries according to the markings in the battery compartment. Replace the battery cover.
2. When the batteries have been inserted, all icons and symbols will be displayed briefly. Do not move
the display before data has been received from the transmitter; otherwise the transmitter will go into
search mode. This can take a few minutes.
3. When data has been received from the transmitter, the display will return to normal display mode,
where all settings can then be input.
4. If no RCC signal is detected in the initial setup, the transmitter will try once every hour to get an RCC
signal until a signal is received. Once the transmitter receives the RCC signal it will transmit the signal
to the receiver/indoor unit and the time and date will be updated. The RCC icon
on the receiver when the correct time signal has been received. The icon will not be displayed if
the signal has been lost.
The best time for reception is at night, between midnight and 06.00 in the morning – when there is
less atmospheric interference. During daytime reception of the time signal can not be guaranteed.
Important information regarding RCC clocks
A radio-controlled clock provides a very precise indication of the time because it is controlled by
the atomic clock in Braunschweig Germany (accuracy ±1 second per 1 million year). The mechanism of
the clock contains a radio receiver that decodes the time signal (longwave 77.5 kHz) and adjusts the time.
The transmitter's range is 2000 km, i.e. not reliable north of the Shetlands. The clockwork also has an
accurately calibrated quartz movement with 32 kHz oscillations.
Placement
Once you have established that all the devices are working properly, you can place them in their desired
location. Make sure that the devices function together in their chosen locations before permanently
attaching them. If there should occur a problem with transmission, it can often be solved by moving
the indoor and outdoor unit to another location or moving them closer to each other.
