2. Switch on the flash units in TTL mode. Then switch on the V6 IIs in RX mode.
3. Choose the correct flash profile for each V6 IIs.
4. If you may command the flash to fire above the x-sync speed, turn on the HSS
flash on your flash units (see Section 13.1).
12.1 Relative Power
Similar to a common flash display, the V6 IIs TX indicates the power level of the
remote flashes in proportion to full power in relative power mode, i.e., 1/1 for full
power, 1/2 for half power, etc. Upon switching on the V6 IIs in TX mode, the LCD will
show the relative power levels of all activated groups.
Note that the small single digit indicates the increment between major power levels.
12.1.1 Single Group Power Adjustment
There are two ways to adjust the power level of a particular slave group.
1. Press and hold the group button until the power level of the chosen group is
highlighted on the LCD. Turn the selection dial to the desired power level. Press
shortly the group button to leave the group selection.
2. Short cut: Press and hold the group button and turn the selection dial
simultaneously. Once the adjustment is finished, release the group button.
You may also adjust the power level of the master flash that you have mounted on
the V6 IIs TX hot shoe (female).
1. Make sure that the TTL pass-through mode has not been activated (see Section
8).
2. Press and turn the selection dial simultaneously to change the power level of
the master flash.
