[. . . ] Infrared (IR) remote controls do not work properly when obstacles between the remote control and the audio/video devices disturb the operating signal. This problem can be solved using radio frequency (RF) as a carrier for IR commands. The Pronto Remote Control, in combination with the RF Extender, can operate audio/video devices from virtually any location. The RF Extender consists of two units: a Receiver unit, and a Blaster unit. [. . . ] The amount of RF interference present is indicated by the rate at which the LED blinks and the brightness of the LED when blinking (a higher rate of blinking and a brighter light means more RF interference). To avoid interference, place the Receiver unit in a position in which the Receiver unit LED blinks and burns as little as possible. Remark Do not operate the Pronto Remote Control while positioning the Receiver unit, since both RF interference and operation of the Pronto Remote Control will cause the LED of the Receiver unit to blink. To find the position with the least amount of RF interference, try out the following steps: 1 Try to create the worst-case scenario, by turning on all devices that may cause RF interference. If the RF Extender and the Pronto Remote Control work properly in this scenario, they will certainly work in other situations. If the LED does not blink, or blinks only sporadically, position the Receiver unit there, and continue with step 7. If the LED still blinks, continue with the next step. Note When the LED blinks only sporadically, with low light intensity, there are no problems with RF interference. 4 Try out other positions moving the Receiver unit around, and check the LED for RF interference. If the LED does not blink, or blinks only sporadically, mount the Receiver unit in that place, and continue with step 7. If the LED still blinks, continue with the next step. You can assign 16 Extender IDs (from 0 to 9 and from A to F). For the three RF Extenders in the picture on p. 4 , you can set the Extender IDs as described below: For situation A , set the Extender ID to 0; For situation B , set the Extender ID to 1; For situation C , set the Extender ID to 2. 1 Choose an Extender ID for the Blaster unit by turning the ID dial with a small screwdriver. 2 On the Pronto Remote Control, choose the same Extender ID for each device controlled by the RF Extender. The red LED on the Blaster unit will blink when the RF Extender receives a correct command. The LED of the Receiver unit will always blink when RF signals are being received, even when the extender ID of the Pronto Remote Control and the Extender ID of the blaster do not match. The LED of the Blaster unit will blink only when the configuration of the Pronto Remote Control matches the Extender ID on the Blaster unit. 4 Repeat this procedure for every RF Extender. How to Avoid Interference from Other Prontos If the red LED on the Blaster unit is blinking without the Pronto Remote Control sending commands, the Receiver unit picks up signals from another Pronto Remote Control on the same channel. You can solve this problem by changing the channel. [. . . ] In this case, you can lower the power levels of the Dual IR emitters, in order to prevent the devices from receiving IR signals intended for another device. Switch Function Switches 1 + 2 Dual IR emitters 1 - 2 Power level Switches 3 + 4 Dual IR emitters 3 - 4 Power level Switch 5 IR blaster On/Off When you decide to control the audio/video devices with Dual IR emitters only, you can turn off the IR blaster of the Blaster unit. You can use dip switches 1 to 4 to set the power level of the Dual IR emitters. To set the power level: For Dual IR emitters 1 and 2, use switches 1 and 2; For Dual IR emitters 3 and 4, use switches 3 and 4. [. . . ]
