• Use the mini stand (tripod socket provided) to prop up the siave unit.
• Use the bounce feature to swing the siave unit's hash body so that
the wireless sensor faces the master unit.
• Indoors, the wireless signal may also bounce off the wall so there is
more ieeway in positioning the siave unit(s).
• After positioning the slave unit(s), be sure to test the wireless
operation before shooting.
• Do not place any obstacles between the master unit and siave
unit(s). Obstacles can block the transmission of wireiess signals.
Q • Even with multiple slave units, all of them will be controlled in the same
way via wireless.

possible to change the master unit's zoom setting. However, note that
the master unit transmits wireless signals to the slave unit(s) with the

position. If you change the master unit's zoom setting, be sure to test the
wireless operation before shooting.

pressing the master unit's test firing button.

more than 8 hours, it will not turn on even if you try to fire a test flash with
therhaster unit In this case, press the slave unit's test firing button to
turn it on.
