how do I
: use them?
Hanimex still distributes Hanimex branded photo equipment in Australia and New Zealand, the web site is Hanimex Australasia http://www.hanimex.com.au/ - they seem to be unable to supply information on older Hanimex products.
The sensor on the front of the camera is called a thyristor. It measures the amount of light reflecting back from the subject and shuts the flash (in microseconds) when enough light has been emitted for proper exposure.
Most electronic flash units use color coding ("borrowed" from the Vivitar 283 flash) to indicate automatic settings. First you note or set the film speed on the chart embossed on the back of the flash. Then you choose which automatic setting you want the flash to operate on, i.e. in your case red or green. The chart should be color coded (i.e. there will be a red colored and green colored column) to indicate the proper f/stop (and distance) for taking the picture, The color coding gives you a choice of distances depending on how far the subject is from the flash. Distance is probably indicated on the chart.
Usually thyristor-controlled flash units have a manual setting also, where the sensor is covered and the flash emits as much light as it is capable of. Setting the flash on manual requires you calculate the f/stop yourself, this requires that you know the Guide Number (power rating) of the flash. Since you apparently don't have the instruction booklet, there's no way to know what the Guide Number is.
This would be much easier to explain holding the flash in my hands instead of typing a long-winded explanation.
