6. Press the Mode Button [2] to toggle between TTL (Through the lens, Automatic) and M (Manual) mode.

Operation in TTL mode (Through the lens, Automatic mode)
In TTL mode the camera dictates the light output of the flashes. If more than one light group is used the
relationships between the energy levels for group A, B and C can be adjusted. This can, for example, be used to
achieve more light on one side of the object.
1. Press the A, B or C Group Button [4] to select the group you want to adjust.
2. Use the Energy Buttons [3] to set the relative light output for the selected group, in relation to the other
groups. The relations can be set ±2.0 f-stop for each group A, B or C. Relations should not be confused with
exposure compensation. (Carefully read “Precautions for use” in the end of this section.)
3. Press the Model Button [9] to turn on/off the modeling light in the selected group(s).
4. Press the Head Button [9] to turn on/off the heads in the selected group(s) (if the heads in a group are
turned off, the relation value for that group will display ‘--’).
5. When changing from M mode to TTL mode, the previous TTL relation values are displayed.
Example of E4 Display[1] settings in TTL mode operation
The corresponding settings of the display shown in the figure are:
- TTL mode, First-curtain synchronization (1st).
- Channel 1, Group A is selected to be adjusted.
- The relative light output from flashes in group B is set to 3.2 f-stops more than flashes in group A. (A to -1.5
f-stops and B to +2.0 f-stops).
- Flashes in Group C are turned off.
- The modeling light is turned on in both group A and B.
Precautions for use
 Relation values should not be mistaken for flash exposure compensation. To compensate the total flash
exposure, always use the flash exposure compensation function in the camera. Refer to camera user
manual for details.
 If flashes without AODELAN TTL support are used in combination with AODELAN flashes in TTL mode, the
flash outputs of the non-TTL flashes are added to the total flash exposure. Such flashes can, for example,
be used to manually set the exposure on the background.
 If an Aodelan-raido-system compatible flash is set to group D, E or F under the same channel, it will be
synchronized but not be part of the TTL calculation. The flash outputs of these flashes are added to the total
flash exposure and can for instance be used to manually set the exposure on the background.

Operation in M mode (Manual mode)
With the E4 set to M mode, the light output for groups A, B and C can be adjusted manually. By alternating
between TTL and M mode, you can test your way to the perfect light.
1. Press the A, B or C Group Button [4] to select the corresponding group, or to select all groups.
2. Use the Energy Buttons [3] to adjust the light output for the group. The adjustment (increase/decrease)
always starts from the current light output setting on the flashes and the adjustment value is momentarily
(approx. 3 seconds) shown in the ENERGY section on the Display [1].
3. Press the Model Button [9] to turn on/off the modeling light in the selected group(s).
4. Press the Head Button [7] to turn on/off the heads in the selected group(s) (if the heads in a group are
turned off, the light output energy value for that group will display “--”)。
Example of E4 Display[1] settings in M mode operation
The corresponding settings of the display shown in the figure are:
- M mode, First-curtain synchronization (1st).
- Channel 1, Group B is selected to be adjusted.
- Flashes in Group C are turned off.
- If the light output for group A or B is adjusted, the energy change will be shown momentarily in the ENERGY
section on the Display [1].
- The modeling light is turned on in group A.
Precautions for use
 The current energy adjustment value is only shown on the Display [1] momentarily and will disappear after
about 3 seconds.
 When you adjust the energy again, the initial value starts again from +/- 0.1 (short press the Energy
Adjustment Button [3]) or from +/- 1.0 (long press the Energy Adjustment Button [3]).
 When all groups are selected E4 will also control the flashes in group D, E or F (selected on flash).
