Understanding your Archsat Remote Blaster. When using a Remote Blaster please keep the following things in mind:   1.    A Remote Blaster is used to transmit your remote signals from your infrared remote control (example your satellite remote) from another room in your house to your main room where you have your SAT/VCR or other devices. This process involves sending a infrared signal (please note that infrared signals do not travel through objects such as chairs cupboards and so on) to the transmitter unit of the Remote Blaster which then is converted to a radio frequency, once converted it is then transmitted (radio frequencies can travel through objects in you house) to the other Remote Blaster unit (receiver) which is in the main TV room (where you have the SAT/VCR this radio frequency is then converted back into infrared and transmitted to your satellite receiver or VCR (remember that infrared signals do not travel through objects).  In your Main TV room the best place for the receiver unit of the Remote Blaster is to have it facing the devices you want to control with direct line of sight (no objects in the path of the signal.).  In the room where you have your second TV it is best to put the transmitter of the Remote Blaster anywhere (in line of sight) that is not close to the TV, computer or any other electrical device that may cause interferences with the blaster (electrical devices do sometimes transmit unwanted signals that could interfere with the blasters signals and cause it not to work properly).  If this is done correctly you shouldn't experience any difficulties. 2.    If you do encounter difficulties then try the following: In your main TV room try moving the Remote Blaster receiver to another position in the room. Take note that infrared signals are light signals and light reflects off of walls, windows and other objects in the house so it is possible that the device you are trying to control is receiving mixed signals and then freezes up, you have to find the appropriate place in the room to minimize this. It is sometimes possible to place the Remote Blaster receiver on top of your TV and face it at the wall directly in from of the TV, the signal will then be reflected back to the devices you need to control. (Remember that your TV could interfere with the blaster so this is not always the best place to put your Remote Blaster). If the distance between the receiver and transmitter of the Remote Blaster is not very far (example: the room next-door) then in some cases the signal from one blaster to the other can be too strong therefore overdriving each other and freezing. This can be overcome by reducing the height of the telescopic antennas of both receiver and transmitter of the Remote Blaster.  3.    It is also important to note that the Remote Blaster will not work if the receiver and transmitter are in the same room! Please also refer to the instructions that come with the REMOTE BLASTER. If you take all these factors into account you will have a great time "Remote Blasting" your signals all over your house. Happy Blasting!
