OPERATION
APPEARANCE
Optic signalling of
transmitter’s operation
Push-buttons
• 4-channel radio transmitter (remote control),
• remote control of EXTA FREE system receivers,
• possibility of independent control of two receivers,
• wide range of operation (up to 250 m),
• battery powered,
• modern design with extra, practical chain finished with a key ring,
• possibility of simultaneous switching on/switching off any number of EXTA
FREE system receivers,
• possibility of increasing operation range by means of RTN-01 retransmitter.
After pressing the push-button the remote control sends a signal on 868.32
MHz which controls EXTA FREE receivers. Device programming procedure (add-
ing a transmitter to the transmitter’s memory) is described in manual instruc-
tion of particular EXTA FREE system receivers.
BATTERY CHANGE
Battery discharge status is signalled by several LED red diode flashes during
transmission time.
1. Remove the screws from the bottom part of the remote control.
2. Remove the upper cover with the silicon keyboard.
3. Remove the battery from the latch.
4. Mount a new battery. Watch battery polarisation marked on the latch.
Wrong battery mounting may cause device damage.
5. Place back the top cover with the keyboard and tighten the screws.
CAUTION: While changing the battery, it is suggested to press any of the but-
tons for about 5 seconds before putting it into a latch. Next press transmission
button several times to check its operation. If the transmitter does not work
properly repeat the battery change procedure.
COOPERATION AND OPERATION RANGETECHNICAL DATA
CAUTION: The given range concerns open area - an ideal condition without any
natural or artificial obstacles. If there are some obstacles between a transmit-
ter and a receiver, it is advisable to decrease the range according to: wood and
plaster: from 5 to 20 %, bricks: from 10 to 40 %, reinforced concrete: from 40 to
80 %, metal: from 90 to 100%, glass: from 10 to 20 %, Over- and underground
medium and high electrical power lines, radio and television transmitters, GSM
transmitters set close to a device system have also a negative influence on the
range.
