2.3 Connecting the Power Supply
• There is a 2-position screw terminal on the back of the unit.
You need to connect a 6 volt (could be 6 to 9v DC) power
supply into these terminals.
• In your package there is either of the following 2 power
supplies.
There is also a 2.5 mm Jack included in the package so that
you don’t have to cut the connector at the end of the supply.
• If you decide to cut the connector at the end of the supply,
then you have to connect it to the screw terminals. The power
supply cable has 2 conductors, the + terminal usually has a
white line or white writing on it. That goes into the + terminal
as noted on the printed circuit board of the UVA-WP. Verify
this with a voltmeter before powering the circuit.
