RAVAK COMPACT 1 -

The remotely controlled device COMPACT1 enables reception of FM radio, switching on the spot light

and timing of the ventilator, if connected. It consists of the power source, control unit, loudspeaker, spot light,

externally switched central light and IR remote controller. All the components (apart from the controller and the

ventilator) are mounted on the mainboard and are electrically interconnected.

Control of COMPACT 1 System (the numbered items correspond to the identification of buttons on Fig.

1).

1. Light

The COMPACT 1 set enables to control the spot light using RC1-L1. By short-pressing Button No. 1, the

light goes on. Press again Button No. 1 to switch off the light.

2. Ventilator

The first pressing of Button No. 2 switches on the ventilator and sets the timer to switch it off in

5 minutes. If you press it once again, the operation interval will be extended to 10 minutes, the third pressing

will extend it to 15 minutes. The fourth pressing of Button No. 2 will end the timing function prematurely and the

ventilator switches off.

3. Radio

Pressing Button No. 3 will switch on the radio on the last selected (tuned) station. The second pressing of

Button No. 3 will switch off the radio. Upon turning off the radio the tuned-in frequency and the volume of the

radio will be stored in memory. The memory content is kept also upon the power failure.

4. and 5. Volume Adjustment

Volume may be adjusted from the minimum level (muted) to the maximum value. Button (+) No.

4 increases the volume from the set value to the maximum, Button (-) No.5 reduces the volume to the

minimum. Short-pressing of the button reduces (-) or increases (+) loudness by one level. Holding the button

pressed reduces / increases smoothly the volume up to the required value.

6. and 7. Scanning the Frequency Band

The switched-on receiver may be tuned to another station using Buttons No. 6 and 7. You can seek the

station by two methods differing by the duration of pressing of the buttons ( "short" and "long" pressing).

The first method is recommended and suitable in most cases. Long-pressing the Button No. 6 will start

the automated tuning towards higher frequencies, long-pressing of Button No. 7 tunes down to lower

frequencies. During the tuning process, the radio sound is muted and the volume is restored once

a sufficiently strong signal is found. If the FM band limit is reached, the tuning continues from the opposite end

of the band in the same in the same direction (that means to lower or higher frequencies). The circuit, which

controls the automated search of stations is sensitive and it may happen, that it stops in a false signal

interference. In this case, start another search by long-pressing the button. If no sufficiently strong signal is

found in the whole band, the last tuned frequency will be restored.

The second tuning method uses stepping by short pressing Buttons 6 and 7. The short-pressing must not

be repeated more than 3x per second, otherwise it could be considered a long pressing. By short-pressing

Button No. 6, the received frequency is increased always by 50 kHz, short-pressing No.

7 Button will reduce the received frequency by 50 kHz. This method is recommended for instance in case of

two equally strong stations near one another or distant stations, which have a weak signal or stations with

interference.

8. Indication LED.

The indication LED serves for the checking of functionality of the remote controller and indicates the

transmission of the control signal.

Autonomous Switch-Off of the System

The COMPACT 1 system is controlled only by the remote controller only. In order to prevent

a continuous operation in the event of battery discharging, the system is equipped with the function of an

autonomous switch-off. All the functions (light circuit and the radio) will be switched off after expiration of a time

interval of 120 minutes from the last pressing of the button.

Central Light

The central light will be connected to the existing installation for the illumination of the room and is

controlled by the switch located near the entrance door.
