Speaker

You may want the speaker off for sensitive shooting, or turn it on for audi- ble confirmation of flash exposure. The earphone signals always sound whether the speaker function is set on or off.

Flash Indicator Lights

The red Flash Indicators on four sides of Qflash give visual indication that a flash fired, weather the exposure was good, over, under, or no flash, indi- cating that the flash did not fire. You can enable or disable the lights.

Reflector settings

Setting the reflector type is important so that the displayed distance, guide number and f/# correspond to the reflector in use. The choices are NORM (for the reflector supplied with Qflash), DIFF (for diffusers supplied with Qflash, and optional QF67A wide-angle diffuser or softbox QF68), BBE
