There are five power-output settings available with

the PZ40X in manual mode, from full power to

1/16 power. First, push the Mode Selector button

continually until “M” is displayed. The flash will then

be in the Manual mode. Please refer to the Chart 1

on page 15 for details on setup. Once the battery

switch is turned to "OFF", the setting "Manual Mode"

is cancelled.

Here are some situations when manual mode is desirable or useful:

1. Daylight synchronization (Flash is used outdoors to lighten shadows or when

the subject is photographed against a strong backlight)

2. When certain focal-length length lenses will be used, such as fisheye type.

3. When a motor drive or an auto-winder will be used.

4. When a number of flashes are used together.

Note: An arrow in the LCD display indicates that the maximum flash range of

105 ft. (32m) has been exceeded.

Mount the PZ40X on the camera and push the

mode-selector button until the LCD panel displays

TTL. The PZ40X now calculates exposure based on

the camera's selected aperture and film speed and

displays the effective TTL distance range. The display

of the effective distance range does not appear until

you partly depress the camera's shutter release or

the Ready Light comes on. A bar graph shows the

flash range display from 1.5 ft to 105 ft (0.5m to 32m). An asterisk will appear if

this distance is exceeded.
