RF remote control function The remote control has the RF remote function in addition to the IR remote function. The VR-510 can receive the remote control commands even when they are installed in a position where the IR remote signal can hardly access, for example inside a cabinet. The receiver is not equipped with the RF remote bi-directional communication function. The bi-directional communication is available only using the IR remote function. Changing the RF transmission frequency The RF remote function may be unavailable due to radio wave cross talk, etc. In this case, the transmission frequency can be changed. To change the RF remote transmission frequency: 1 Open the battery cover on the rear. Setting up the system Remote control operation 19 When the STANDBY indicator is lit, the power turns ON when you press the SYS. POWER key on the remote control. When the power comes ON, press the key you want to operate. Operating receiver range (RF Transmitter) RF Remote antenna 10 m RF Transmitter Preparations 2 Change the RF switch setting. RF 1 2 Operating other component range (IR Transmitter) 6 m IR Transmitter After changing the RF frequency of remote control, be also sure to change that of the receiver. 3 Change the receiver's RF reception frequency. • Press and hold the SET UP key on the front panel of the receiver for more than 2 seconds. Each time you press the SET UP key, the RF reception frequency changes as follows: 1 "RF BAND 1" 2 "RF BAND 2" 3 "RF OFF" • Select the same number as the position number of the RF switch of the remote control. Loading the batteries 1 Remove the cover. 2 Insert the batteries. 3 Close the cover. • Insert four AA-size (R6) batteries as indicated by the polarity markings. • The remote control signal received by the main unit are IR and RF signals. • When pressing more than one remote control key successively, press the keys securely by leaving an interval of 1 second or more between keys. Notes 1. The supplied batteries may have shorter lives than ordinary batteries due to use during operation checks. 2. When the remote-controllable distance gets shorter than before, replace all batteries with a new ones. 3. Placing the remote sensor in direct sunlight, or in direct light from a high frequency flourescent lamp may cause a malfunction. In such a case, change the location of the system installation to prevent malfunction. Important notes Here is list of adjustment which can maximize the operation of your remote control. For optimal operation of the remote control: 1 Aim the remote control toward the room where the receiver is located. 2 Do not position the receiver and remote control near metal (such as heat ducts). Metal can absorb RF signals. 3 Make sure the batteries in the remote control are fully charged. Weak batteries will affect the range of the remote control. 4 When there is an obstruction around other equipments that send signal from the remote control, the control distance of the RF remote signal will be short. Note • The tests for range limits of the remote control and the receiver are conducted in open-air distance test. Actual distance of the signal will be based on the construction of the building the unit is being used in as well as other factors such as outside interference.
