Vision Plus VP4 Digital TV Amplifier & Signal Finder
Positioning and Fixing
In order to boost / amplify the signal that your television receives it is necessary to fit the VP4 amplifier between your aerial / antenna and the television itself. This means that the lead coming from your aerial must first go into the amplifier using the port / socket marked 'ANT IN'. You will then take a 'flylead' from any one of the sockets marked TV1, TV2 or TV3 to the television. If you have a standard coax flylead you can use the adapters provided with the VP4 to enable the connection.
If you so desire, the VP4 can be fixed to the inside of a cupboard using the units fixing points and the fixing screws provided - but this is not absolutely necessary, it can be left to sit freely if you wish. If you do fix it, remember there is an on /off switch on the unit that you may want to have access to.
The amplifier requires a 12-24 volt power supply and can be wired directly to the battery. However, you should note that if are planning to wire directly to the battery then an in-line fuse ( 5amp max ) must be fitted on the positive wire. Alternatively, you can use a 12v DC Mains Adapter ( not supplied - Vision Plus advise that you use their 12v DC Mains Adapter )
Brief Operating Instructions for the Vision Plus VP4
These are not comprehensive instructions but a guide to give you a good idea of how the VP4 operates. When you switch on the VP4 the LED light on the top will light up. It is now a matter of rotating / moving the aerial whilst watching the signal indicator to find the direction of the best signal from the transmitter.
