Need to understand how to set manual settings
SOURCE: Sunpak 522 and 544 always firing full power
The probable cause of such behavior is a faulty quench capacitor. The part is specially manufactured to withstand rather high voltage (350 V) and large current peaks (300 A) - despite of its small dimensions - and often goes wrong. Replace it with a capacitor cannibalized from a cheap second-hand shoe-mount flash having the same feature (series thyristor circuitry) and as high guide number as available. Both Sunpak units are highly populated inside, only try to repair them if you have a certain skills in such a job. If any of these explanations is unfamiliar for you then leave the flash alone and take it to a repair shop - there is lethal voltage inside, even long after the unit has been switched off. Good luck!

SOURCE: flash works intermittantly
There can be more than one causes.
If intermittent work mean that in, at least, some cases the strobe fires normally and the internal sensor controls the power as it should, then the most probable cause is a diry contact at the either end of the PC cord or a broken wire in the cord. Clean with any gentle method or disconnect-reconnect a dozen times in order to rub off the oxidization, or replace in the latter case.
If it doesn't help then the culprit can be a cold solder joint inside the flash, the repair of which asks for a technician with skills.
If the intermittent work means that the flash always fires, but sometimes with the correct power and sometimes with full power, then the case is more sophisticated, and surely needs a repair of internal circuitry. See the description of such issue for a Sunpak 522 elsewhere in Fixya
Good luck, Laszlo

Seems like you may be ok. Google pentax k20d supak 344d compatability.

Firstly, be sure to check flash voltage. Your 30D may accept max 6V so that your camera can be shot if the flash unit has higher voltage than 6V.
1. Use low ISO to keep low noise....around f/8 or more depends on your need and how much DOF you want.....Set the shutter speed around 1/125 to your max speed to stop any movement (your subject or camera itself shaking).
2. Above is set in Manual mode (iso100, f/8 1/125 or 1/250), then you just need to leave the flash to work in TTL mode.
3. It needs battery, the connection is for syncing to trigger and release a proper flash power (in TTL mode).
Hope this help!

Hi, I am looking into purchasing a Sunpak DX 8R, it includes the NE-3D Module for the Nikon F3 (If this is what you are looking for) which I have no use for. If you are interested, please advise,Thanks
