PROBLEM: The thing just doesn't work! It must be the engineer's fault!
SOLUTION: We make absolutely sure that our products work beyond expectations before the kits leave our doors. If you can't solve the problem, send in the kit, if it's our fault the fix charge is free. Read the warranty information in the back of the manual for more information.
USING YOUR URC1
There is so many things you can do with a kit of this nature, that we will only go into some of the possibilities. Many more things can be done with it than what is being shown, just use some of the basic principles shown here and your imagination and you will be churning out the projects that will even impress the experts!
Connecting a relay to a switched output:
Once connected to the relay, the URC1 can turn a number of devices on and off, such as home security systems, lights, answering machine, lawn watering system, swimming pool filters, etc. Be sure the coil on the relay has a resistance of no less than 100 ohms to be safe. If it is less, use a transistor with a higher power dissipation rating.
Using a Level output as an isolated Variable Resistor:
This is a simple, yet useful way of isolating the URC1 from the unit being controlled. This setup will work well for any circuit (within current limits) that requires a variable resistance. For example this can be used to control a form of squelch on a radio called level detection. This simple circuit can be used in
