Using the Radio (off camera) 
To enable the Trio to be fired remotely set the internal radio to RX. An 
FW9T or FW10w must be located at the camera position, or you can use 
another Trio at the camera position. 
Be sure that the channel and zones match the channel and zones set on 
the Trio. See section 8.0 for setting the Channel and Zones on the Trio 
11.3 Auto mode soft keys 
To change the function of the soft keys use the Left (-) Å and Right Æ 
buttons when no selection or setting is highlighted on the display. 
If the radio is turned off, the Default and Sensor Limit soft key functions 
available are shown below. 
If the radio is on, then the zone control soft keys are available. Press a 
soft key to turn a zone on or off. 
11.4 Auto mode exposure indications 
There are three types of exposure indications. The display will blink 
either OK, Over, or Undr. The display will also indicate how much over or 
under the last exposure was, from +3 stops to -3 stops. If an arrow 
appears then the exposure error is more than 3 stops (for example -3Å). 
If activated in Options (Section 9.3)  the Speaker will sound after a flash. 
The audible signal is one “beep” for “OK and flash ready”, and three 
“beeps” for “Undr” or “Over”. 
11.5 Auto Sensor Limit 
Setting Qflash to Auto mode makes picture taking fast and easy.  
However, an automatic flash has a flaw: the sensor on the flash expects 
the subject to be wide, flat, and to fill the view of the sensor. A person 
standing against a wall fits this description; people in a catering hall or in 
a park at night do not. When the background is located far behind the 
subject, the automatic flash struggles to produce even lighting. The 
result is often an over exposed subject, sometimes by as much as two 
stops. When a photo lab develops film with a greatly over exposed 
subject, it will ‘print down’ to bring the flesh tones back into range. Or, 
time will be spent adjusting a digital image, with the resultant loss of 
detail and image quality.
