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.

Power Management
Use ON/OFF Power Switch to power the ash unit on or
off. Turn off if it will not be used for an extended period of
time. Setting as a master ash, it will turn the power off
automatically after a certain period (approx. 90 seconds)
of idle use. Pressing the camera shutter halfway or
pressing any ash button will wake up the ash unit.
Setting as a slave ash, it will enter sleep mode after a
certain period (adjustable, 60 minutes by default) of idle
use. Pressing any ash button will wake it up.
Disabling Auto Power Off function is recommended
when the ash is used off camera. (C.Fn-APO)

This ash has three ash modes: E-TTL, Manual (M),
and MULTI (Stroboscopic). In E-TTL mode, the camera
and the ash will work together to calculate the correct
exposure for the subject and the background. In this
mode, multiple TTL functions are available: FEC, FEB,
FEL, HSS, second curtain sync, modeling ash. These
can be controlled with the Modus 600RT or with the
camera’s menu screen.
* Press < MODE > Mode Selection Button and three ash modes
will display on the LCD panel one by one with each pressing.

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: Multi (Stroboscopic
Flash)
With stroboscopic ash, a rapid series of ashes is red.
It can be used to capture multiple images of a moving
subject in a single photograph.
You can set the ring frequency (number of ashes per
sec.expressed as Hz), the number of ashes, and the
ash output power.
Calculating the Shutter Speed
During stroboscopic ash, the shutter remains open until
the ring stops. Use the formula below to calculate the
shutter speed and set it on the camera.

GB
GB
24 Modus 600RT - English Modus 600RT - English 25
Number of Flashes / Flash Frequency
= Shutter Speed
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
frequency.

• When the camera’s shooting mode is set to a fully
automatic mode or an Image Zone mode, the operations
in this chapter are not available. Set the camera’s shooting
mode to P/Tv/Av/M/B (Creative Zone Mode).
• The “Modus 600RT” attached to the Camera Hot shoe is
called the “Master” unit. A second “Modus 600RT” which is
wirelessly controlled is called the “Slave” unit
• You can also wirelessly control the Modus 600RT as a
“Slave” unit using a “Viper TTL” transmitter as a “Master”
unit attached to the camera hotshoe
Using (Master/Slave) with wireless 2.4GHz control
function allows you to easily perform shooting with
advanced wireless multiple ash lighting in the same
way as E-TTL II autoash photography. The system is
designed so that the setting’s of the “Master” attached to
the camera are automatically applied to the wireless slave
speedlights. Therefore you do not need to operate or
adjust the slaves during shooting

You can divide the slave units into two or three groups and
perform E-TTL II autoash while changing the ash ratio
(factor). In addition, you can set and shoot with a different
ash mode for each ring group, for up to 5 groups.

Wireless shooting using radio transmission has
advantages over wireless shooting using optical control,
such as being less affected by obstacles, and not having
to point the slave unit’s wireless sensor
toward the master unit. The main functional differences
are as follows:

slave units. So the only thing you need to do is to set
the master unit to ETTL mode without any operation for
the slave units at all during the shooting.
• This ash can work in ETTL autoash, M manual ash,
