Battery and Charger
• The Modus 600RT uses a lithium ion battery HLX-MD1
and it must be charged before use
• Use only the MD1 charger to charge the battery
• Remove battery from charger when charging is nished
and disconnect charger from mains
A fully charged battery will offer approx 500 ashes at full
power and even more when power level is reduced. The
composition and construction of the MD1 battery pack
offers very reliable and fast refresh time for the speedlight.
How to store the battery
When not in use remove battery from the charger or
the speedlight and store battery in a cool and dry place.
Exposing the battery to higher temperature can shorten
the lifetime of the battery. Store the battery almost empty
(one bar in the battery level indicator) when not used for
a long period of time. For optimum battery life use battery
regularly and if not used for more than 6 months charge
the battery fully and use it with the Modus 600RT until the
battery level is down to 1 bar again before storage.
Battery Lifetime
The lifetime of a recharable battery is limited. The capacity
will drop progressively with use and age of battery
pack. Replace the battery pack when the ash cycle
time becomes longer or the number of ashes reduces
noticeably. The battery lifetime can vary substantially
depending on storage, operation conditions and exposure
to unsuitable enviormental conditions
Caution
• Do not short circuit the battery
• Do not drop battery into water or re
• Do not drop or dismantle or subject the batteries to
strong impact or continuous mechanical shock
• Stop using the battery if the battery has any signs of
damage or bulging to housing and dispose of battery in
accordance with the appropriate local regulations
How to charge the battery
The HLX-MD1 battery must be charged before use. Use
only the supplied MD1 charger to charge the battery.
Connect the MD1 charger to the mains with the supplied
mains cable and the power LED will light up red if
connected correctly. To start the charge insert the HLX-
MD1 battery into the MD1 charger and the green LED
bars will start to illuminate, indicating that the battery is
charging. 4 green LED’s on indicates full charge. Remove
the battery from charger when fully charged.

The ash output is adjustable from 1/1 full power to
1/128th power in 1/3rd stop increments. To obtain a
correct ash exposure, use a hand-held ash meter to
determine the required ash output.
Flash Output Power Range
The following table makes it easier to see how the stop
changes in terms of f/stop when you increase or decrease
the ash output.
For example, when you decrease the ash output: 1/2,
1/2-0.3, or 1/2-0.7, or increase the ash output:1/2,
1/2+0.3, 1/2+0.7, 1/1.

Optical O1 Secondary Unit Setting
In M manual ash mode, press <O1/O2> button so that
this ash can function as an optical O1 secondary ash
using its optical sensor. With this function, the ash will
re synchronously when a second main ash res. This is
the same effect as usng a radio trigger to re the ash off
camera. This helps create multiple lighting effects.
Optical O2 Secondary Unit Setting
In M manual ash mode, press <O1/O2> button so that
this ash can function as an optical O2 secondary ash
using its optical sensor. With this function, the ash will
re synchronously when a second main ash res as in
O1 but it will ignore the metering pre-ash and re only in
response to the exposure ash from the main unit.
• O1 and O2 optic triggering is only available in Mmanual
ash mode.
Flash Mode: RPT (Stroboscopic
Flash)
With stroboscopic ash, a rapid series of ashes is red.
It can be used to capture multiple images of a moving

For example, if the number of ashes is 10 and the ring
frequency is 5 Hz, the shutter speed should be at least 2
seconds.
• To avoid overheating and deteriorating the ash head,
do not use stroboscopic ash more than 10 times in
succession
• After 10 times, allow the speedlight to rest for at least 15
minutes. If you try to use the stroboscopic ash more than
10 times in succession, the ring might stop automatically
to protect the ash head. If this happens, allow at least 15
minutes’ rest for the speedlight
• Stroboscopic ash is most effective with a highly reective
subject against a dark background
• Using a tripod and a remote control is recommended.
• A ash output of 1/1 and 1/2 cannot be set for stroboscopic
ash
• Stroboscopic ash can be used with“buLb”
• If the number of ashes is displayed as “--”, the ring
will continue until the shutter closes or the battery is
exhausted. The number of ashes will be limited as shown
by the following table.
Maximum Stroboscopic Flashes:
If the number of ashes is displayed as “--”, the maximum number of
ashes will be as shown in the following table regardless of the ash
