Battery and Charger

•The HLX-MD1 battery must be charged before use.

•Use the supplied MD1 MKII charger to charge the battery.

•Remove battery from charger when charging is finished and disconnect charger from mains

A fully charged battery will offer approx 500 flashes 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 the battery from the charger or the speedlight and store the battery in a cool and dry place. Exposing the battery to higher temperatures 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 the age of the battery pack. Replace the battery pack when the flash cycle

time becomes longer or the number of flashes reduces noticeably. The battery lifetime can vary substantially depending on storage, operation conditions and exposure to unsuitable enviormental conditions

14	Modus 600RT

Caution

•Do not short circuit the battery

•Do not drop the battery into water or fire

•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 the to housing and dispose of the battery in accordance with the appropriate local regulations

How to charge the battery

The HLX-MD1 battery must be charged before use. Use the supplied MD1 MKII charger to charge the battery. Connect the MD1 MKII charger to a USB adapter (min 5V 2 Amp) with the supplied Micro USB Cable . To start the charge insert the HLX-MD1 battery into the MD1 MKII charger and the green LED bars will illuminate, indicating that the battery is charging. 4 green LED’s on indicates full charge. Remove the battery from charger when fully charged.

Flash Mode - TTL Autoflash

This flash has three flash modes: TTL, Manual (M), and MULTI (Stroboscopic). In TTL mode, the camera and the flash will work together to calculate the correct exposure for the subject and the background. In this mode, multiple TTL functions are available: FEC, HSS & second curtain sync, modeling flash. These can be controlled with the Modus 600RT or with the camera’s menu screen.

* Press < MODE > Mode Selection Button and three flash modes will display on the LCD panel one by one with each pressing.

TTL Mode

Press < MODE > Mode Selection Button to enter TTL mode. The LCD panel will display TTL.

•Press the camera release button halfway to focus. The aperture and effective flash range will be displayed in the LCD panel.

•When the shutter button is fully pressed, the flash will fire a preflash which the camera will use to calculate the correct flash output power the instant before the photo is taken.

FEC: Flash Exposure Compensation

With FEC function, you can adjust the calculated level from -3 to +3 in 1/3 stops. It is useful in situations where minor adjusting of the TTL system is needed based on the lighting environment.

Setting FEC:

1. Press Function Button

2 < >. The

icon < > and flash exposure compensation amount will be highlighted on the LCD panel.

18	Modus 600RT

2. Set the flash exposure compensation amount.

• Turn the Select Dial to set the amount.

• “0.3”means 1/3 step, “0.7”means 2/3 step.

• To cancel the flash exposure

compensation, set the amount to “+0”.

3. Press < SET > button again to confirm the setting.

Optical O1 Secondary Unit Setting

In M manual flash mode, press <O1/O2> button so that this flash can function as an optical O1 secondary flash using its optical sensor. With this function, the flash will fire synchronously when a second main flash fires. This is the same effect as usng a radio trigger to fire the flash off camera. This helps create multiple lighting effects.

Optical O2 Secondary Unit Setting

In M manual flash mode, press <O1/O2> button so that this flash can function as an optical O2 secondary flash using its optical sensor. With this function, the flash will fire synchronously when a second main flash fires as in O1 but it will ignore the metering pre-flash and fire only in response to the exposure flash from the main unit.

• O1 and O2 optic triggering is only available in M manual flash mode when the Modus 600 RT is off camera

•Press function button 4 < SYNC > to activate the “HSS” when in 01/02 mode

Flash Mode: MULTI (Stroboscopic

Flash)

With stroboscopic flash, a rapid series of flashes is fired. It can be used to capture multiple images of a moving subject in a single photograph.

You can set the firing frequency (number of flashes per sec.expressed as Hz), the number of flashes, and the flash output power.

1. Press <MODE> button so that < MULTI > is displayed

2. Turn the Select Dial to choose a desired flash output power

Calculating the Shutter Speed

During stroboscopic flash, the shutter remains open until the firing stops. Use the formula below to calculate the shutter speed and set it on the camera.

Number of Flashes / Flash Frequency

= Shutter Speed

For example, if the number of flashes is 10 and the firing frequency is 5 Hz, the shutter speed should be at least 2 seconds.

• To avoid overheating and deteriorating the flash head, do not use stroboscopic flash 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 flash more than 10 times in succession, the firing might stop automatically to protect the flash head. If this happens, allow at least 15 minutes’ rest for the speedlight

•Stroboscopic flash is most effective with a highly reflective subject against a dark background

•Using a tripod and a remote control is recommended.

•A flash output of 1/1 and 1/2 cannot be set for stroboscopic flash

•Stroboscopic flash can be used with“buLb”

•If the number of flashes is displayed as “--”, the firing will continue until the shutter closes or the battery is

exhausted. The number of flashes will be limited as shown by the following table.

Master/Slave wireless flash lighting

• 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 flash lighting in the same way as TTL autoflash photography. The system is designed so that the settings 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

Using Automatic Wireless Flash with Multiple Slave Units

When stronger flash output or more convenient lighting operation is needed, increase the number of slave speedlight’s. To add slave units, use the same steps as setting “automatic wireless flash with a single slave unit” (Page 28). Any slave speeedlight can be set as group (A/B/C).

When the number of slave units is increased or the master flash firing is set to ON, automatic control is performed to fire all flashes at the correct flash output to ensure that the total flash output results in the standard exposure.

•If the slave units auto power off takes effect, press the master unit’s test flash button to turn on the slave unit. Note that the test flash cannot be performed while the camera’s metering timer, etc. is operating

•The slave units auto power off setting can be changed (C.Fn-Sv / APOT page 42)

•In the C.Fn settings you can enable a beeper to sound when a Modus 600RT is recharged and ready to fire again

Advanced setting with fully automatic wireless flash

With the wireless system the following functions set on the master unit will automatically be adjusted on the slave unit. For this reason you do not need to operate the slave unit (s) and can operate it from the master in the same way as normal flash photography.
