BRONCOLOR RADIO FREQUENCY SYSTEM 2.2
Before use
We are very pleased you have chosen one of our RFS 2.2 transceiver units. If used properly, it will render you many years of good service. Please read the information contained in these operating instructions carefully. They contain important details on the use, safety, and maintenance of the device. Keep these operating instructions in a safe place and pass them on to further users if necessary
With the radio system brown color RFS 2.2 you can trigger and operate by remote control brown color units, which are equipped with an integrated RFS 2 interface. RFS 2.2 is available in four versions, for Canon, Fujifilm, Nikon, and Sony, always optimized for its operation. The use of other camera systems is not recommended.
With the additional HS function, HS-compatible brown color flash units, in combination with a suitable camera, can be set to use the shortest possible shutter speeds (down to 1/8000 s).
The transceiver can be operated in either of two modes. As supplied, the transceiver operates as a transmitter.
RFS 2.2 TRANSCEIVER AS TRANSMITTER
The RFS 2.2 transceiver operates as a remote control or radio flash trigger for one or more broncolor power packs or monolights equipped with an RFS 2 interface. Power packs or monolights not equipped with an RFS 2 interface can be operated by connecting an RFS 2.2 Transceiver (as receiver) – see Chapter 10.
All devices, whether with a built-in RFS 2 or an external RFS 2.2 receiver are compatible. If several RFS 2 units are to communicate with each other, they must be set to the same studio address. RFS 2 units with the same studio address can be remote-controlled simultaneously. By using different studio addresses, several groups of devices can be reliably operated independently of each other. Flash synchronization takes place either via the hot shoe or using the camera’s sync contact. The operating distance is up to 50 m in the open air, or up to 30 m in a building. The transmitter is fitted with two AA batteries.
Attention! Although this radio system allows up to 99 studio addresses, the number of channels that is effectively available is restricted by the RFS 2 flash unit to be controlled.
For further instructions, please see the operating instructions for the flash unit concerned.
OPERATION
Keys
The unit has three menu keys, a scrolling wheel, a “test” key and two slide switches, one for modeling light and one to switch the unit on and off.
> Duration of key presses
A short press of a key is one that takes less than one second, a long press is longer than one second.

SETTING STUDIO ADDRESSES
The transceiver must have the same studio address as the flash units used. First set the studio address you want to use on the flash units, and then synchronize the RFS 2.2 transmitter.
To set the studio address (studio channel), please proceed as follows:
- Press the “ST” key for longer to enter the studio channel menu.
- Set the studio address with the scrolling wheel as required (01 to 99).
- Save the setting with a short press on the “ST” key. The transceiver syn- chronicles with the flash units.
SETTING THE LAMP CHANNEL
With the RFS 2.2 transceiver, you can set the energy control per channel as you wish as well as adjust the number of lamps per studio.
To set the lamp address, please proceed as follows:
- Press the “LP” key briefly to enter the lamp setting menu.
- Set the lamp address with a short press on the “LP” key (several times if necessary).
To set the number of lamps used in your studio, please proceed as follows:
- Press the “LP” key for longer to enter the lamp setting menu.
- Set the number of lamps used in your studio with the scrolling wheel as required (01 to 40).
- Save the setting with a short press on the “LP” key.
ENERGY CONTROL
5.1 Preparation
A longer press on key “ST”: Turn the scrolling wheel as appropriate to change the studio channel up or down. Confirm the selection by a short press on key “ST”.
The RFS 2.2 transceiver allows you to change the energy setting of all RFS 2 flash units that are set to the same studio address (in the “ST” menu) and to change the output of individual lamp channels (in the “LP” menu). The output can be adjusted in 1/10 and full f-stop steps.
5.2 Menu “ST”
A short press on key “ST”: Turn the scrolling wheel upwards or downwards to increase or reduce the total energy of all units. This takes place in 1/10 f-stop steps. Confirm the selection by a short press on key “ST”.
5.3 Menu “LP”
A short press on key “LP”: Turn the scrolling wheel upwards or downwards to increase or reduce the energy of selected lamps. This takes place in 1/10 f-stop steps. Confirm the selection by a short press on key “LP”.
HS
6.1 Menu “HS”
The HS mode enables short exposure times (down to 1/8000 s) on the camera in combination with HS-compatible flash units.
Operating HS functions
- Mount a compatible RFS 2.2 transmitter on the camera
- Switch on the RFS 2 / HS-compatible broncolor flash unit
- Activate the RFS function on the flash unit
- Activate HS mode on the RFS 2.2. The flash unit switches automatically to HS mode
HS on / off
Press the “HS” key briefly: Turn the scrolling wheel up or down. HS mode switches on and off. Confirm the selection by a short press on key “HS”.
6.2 Menu “HSMA”
When HS is active, HSMA (HS Manual Adjust) improves the exposure to suit the camera model being used. The purpose of HSMA mode is to override the automatic HS flash trigger. The automatically calculated shutter release is canceled.
The delay of the flash trigger signal (HSMA) depends on the camera, and so is different from model to model. The transmitters are factory set to work correctly with most models of a given brand, however, if you should notice a black bar across the exposed image you should utilize the HSMA function to adjust the timing until the black bar is no longer visible in the exposed image.
longer press on key “HS” for HSMA (HS Manual Adjust): turn the scrolling wheel up or down. In this way, HSMA mode can be set individually. Confirm the selection by a short press on key “HS”.
