1、User Manual1IntroductionAbout the SBC LI970Most remote control systems have to be operated by pointing the remote controldirectly towards a device. Any obstacle between the remote control and the devicedisturbs the operating signal. But what if you like to place your devices inside aclosed cabinet,

2、a closet or even in another room?The SBC LI970 provides the solution to overcome obstacles like furniture or walls.Your devices no longer have to be placed in line of sight but can be operated fromvirtually any location. The SBC LI970 is a RF Extender that is used in combinationwith the ProntoPro Re

3、mote Control. The RF Extender receives radio frequency(RF) signals sent out by the ProntoPro and converts them into infrared (IR) signals.These IR signals are then sent out to your TV, DVD, preamplifier and so on.IntroductionProntoPro RF ExtenderRF signals IR signalsSBC LI970 13-11-2001 09:54 Pagina

4、 1User Manual2IntroductionPossible Set-upsThe RF Extender can be used in several situations: Your devices can be remotely controlled while the RF Extender is placed in lineof sight (situation A). The RF Extender controls devices placed in an adjacent room (situation B). The RF Extender is placed ins

5、ide a closet, a rack or another piece of furnituretogether with your devices (situation C). The set-ups in situation A, B and C can be combined. If you want to controldevices in different locations, you have to place a RF Extender in eachlocation. You can control all RF Extenders with the same Pront

7、4 screws.Before you install the RF Extender, you should decide which of the set-upsdescribed on p. 2 apply to your needs. It is recommended to read through theentire User Manual.Working Angle and Range of the IR blasterWarning The IR signals sent out by the RF Extender always have to be able to reac

8、h thereceiving eyes of your devices. Make sure that the IR blaster (dark plastic windowon top of the RF Extender) is aimed at your devices.To get optimal results, it is recommended to place the RF Extender horizontallywith the IR blaster facing up or down.Figure 1 represents the RF Extender mounted

9、up side down inside a closet.Always maintain a minimum distance of 4 inches (10 cm) between the RF Extenderand your devices.Figure 2 represents the RF Extender with the IR blaster facing up. The RF Extendercan be placed at a distance and higher than your devices. Make sure there are noobjects betwee

11、e using the includedmounting plate and the 4 screws. Take into account the range and the workingangle of the IR blaster as explained on p. 3. Also make sure to place the RF Extender in a central position aimed directly at your devices.Warning It is adviced not to place the RF Extender inside or near

12、 a metal closet as RF signals can be disturbed by metal objects.Installation1 Remove the mounting plate from the bottom of the RF Extender.2 Screw the plate to a rack, closet or another piece of furniture. Provide sufficient space to connect the power adapter and to slide theRF Extender back on.Note

13、 Depending on the surface, it may be possible to attach the RF Extender to thefurniture using a piece of 2-sided tape. Look for the right position and make surethere is sufficient space.3 Slide the RF Extender on the mounting plate.Using the Dual IR EmittersLike the IR blaster of the RF Extender, th

14、e dual IR emitters send out IR signals.You can use the dual IR emitters as an alternative for the IR blaster.When to use the emittersThe IR emitters can control devices the IR blaster cannot reach, for instance whenthere is limited space around the receiving eyes of the devices, e.g. in a smallclose

15、t.Note The IR emitters can also be used in combination with the IR blaster of the RF Extender. Both send out IR signals simultaneously. This allows you to operateseveral devices using both the IR blaster and the IR emitters.SBC LI970 13-11-2001 09:54 Pagina 4User Manual5InstallationHow to use the em

16、ittersThe dual IR emitters can be attached to the surrounding surface facing thereceiving eyes or directly to the receiving eyes. 1 Attach the emitters to a surface above, below or in front of thereceiving eyes of your devices (for aesthetic appearance or when it isdifficult to locate the receiving

17、eye). or Attach the emitters directly to the receiving eyes of your devices.2 Plug the dual IR emitters into the RF Extender.Note To avoid interference, the wires of the emitters should be kept away from the RF Extender as far as possible.Connecting the Power AdapterWhen connecting the power adapter

18、 it is recommended that you plug the adapter into the RF Extender before you plug it into the socket. When connected you will see a red LED on the RF Extender.Note To avoid interference, the adapter cable should be kept away from theRF Extender as far as possible.SBC LI970 13-11-2001 09:54 Pagina 5U

19、ser Manual6InstallationSettingsAs the RF Extender communicates with the ProntoPro Remote Control, you haveto set the same Extender ID (identity) on both appliances. The settings depend onwhether you have a single RF Extender or multiple RF Extenders.Single RF ExtenderWhen you use only one RF Extende

20、r, you can accept the default setting for theExtender ID (ID=0). Make sure your ProntoPro Remote Control is set to the samedefault setting (see the ProntoPro User Manual for more details).Multiple RF ExtendersIf you want to operate several of your devices independently, e.g. grouped ondifferent loca

21、tions, you will need multiple RF Extenders. When using several RF Extenders, it is important to assign a unique Extender ID to each RF Extender.16 Extender IDs (from 0 to 9 and from A to F) can be assigned.1 Choose an Extender ID for the RF Extender by turning the ID dial with a small screwdriver.2

22、On the ProntoPro Remote Control, choose the same Extender ID for each device controlled by the RF Extender.Refer to the ProntoPro User Manual for more information.3 Try to operate your devices with the ProntoPro Remote Control.The red LED will blink when the RF Extender receives a correct command.4

23、Repeat this procedure for every RF Extender.RF InterferenceIf your devices are not responding to commands or if the red LED on the IR blasteris blinking without sending commands, it might be possible that there is RFinterference. This can be the case when other RF appliances are operated nearby,for

24、instance at your neighbours.When you notice RF interference, you have to choose another channel on your RF Extender. 4 channels (CH from 0 to 3) can be assigned.1 Choose a channel for the RF Extender by turning the CH dial with asmall screwdriver.2 On the ProntoPro Remote Control, choose the same ch

25、annel for thedevices controlled by the RF Extender.Refer to the ProntoPro manual for more information.3 Try to operate your devices with the Remote Control.SBC LI970 13-11-2001 09:54 Pagina 6User Manual7TroubleshootingTroubleshootingDevices do not respond properly Check if the power adapter is conne

26、cted and the red LED is on. Check if the ID and channel numbers on the RF Extender match with the ID andchannel numbers on the ProntoPro Remote Control (see p. 6). Refer to theProntoPro User Manual for more details on the settings of the Remote Control. Check the placement of the RF Extender: Check

27、the distance between the RF Extender and the ProntoPro RemoteControl (see p. 2). Check the range and the working angle of the IR blaster (see p. 3). Check if the RF Extender is placed in a central position relative to yourdevices (see p. 4). Make sure that the distance between the RF Extender and yo

28、ur device isat least 4 inches (10 cm). Make sure that the distance between the RF Extender and your device isat most 16 feet (5 m). Make sure the IR signals between the RF Extender and the receiving eyesof your devices are not disturbed by any objects. Check if metal objects, for instance a metal cl

29、oset, wires or cables,surrounding the RF Extender do not disturb the RF signals. If you are using the dual IR emitters, make sure they are connectedproperly and that they are placed within range of the receiving eyes (see p. 5). It might be possible that some commands cannot be sent out as RF signal

30、s. In that case you will have to reconfigure the ProntoPro Remote Control tooperate your devices with IR signals again.The red LED on the RF Extender blinks without using the ProntoProRemote Control This indicates RF interference.
