Attention: Read before starting up the compact unit - Prior to replace fuses, modelling lamp or flash tubes, discharges the unit anddisconnect it immediately from power supply. Prior to replacing the modelling lampor flash tube, let the unit cool down for a period of 10 minutes. - The unit is designed for use in dry conditions. Protect it form water and fromexcessive exposure do dust. - The unit is not suitable for use in an environment where there is a risk ofexplosure. - The accessories mounted onto to the compact unit may heat up to high temperatures under specific conditions. Handle with care. - With due allowance for heat radiation, units with more than 100 W modelling lightmay be directed against inflammable surfaces only at a minimum distance of 1meter. - For safety reasons, never operate the unit without protecting glass in place. - Flash light contains, similar to sunlight, a specific portion of UV light. Theundesirable side effects on skin and eyes are considerably reduced by using flashtubes and glass covers with an UV coating. Without these or other protectivefilters, use with extreme care when shooting. - Even when disconnected from the power supply, dangerous voltages may remaininside the unit. For this reason, units should be opened by authorized broncolor service shops. - Do not block the cooling louvers on the unit - Only fuses of the type indicated on the safety label may be used. This is especiallyimportant for the halogen lamp which can explode when used with the wrong fuse. Only use sand-filled fuses. They can be identified by their opaque fuse container. 3

1. Application Minicom This mains supplied studio flash unit is designed for professional photography only. In countries with earthed mains systems, use a three-wire extension cable when required. 2. Start up 2.1 Mains voltage The compact units Minicom 40 and Minicom 80 are available in two different versions: a) As a bi-voltage-unit, of which the technical data are optimised for a mains voltage of 200 - 240 V. If this version is operated with a mains voltage of 100 – 120 V, the following restrictions result: Mains voltage 120 V: doubling of the charging time Mains voltage 100 V: doubling of the charging time as well as reduction of the maximum flash energy of 250 J (Minicom 40) respectively 500 J (Minicom 80), extension of the flash duration by 20 % b) As a bi-voltage-unit, of which the technical data are optimised for a mains voltage of 120 V. If this version is operated with a mains voltage of 200 – 240 V or 100 V, the following restrictions result: Mains voltage 230 V: doubling of the charging time Mains voltage 100 V: Extension of the charging time by 20% as well as a reduction of the maximum flash energy of 250 J (Minicom 40) respectively 500 J (Minicom 80), extension of the flash duration by 20 % Attention: The operating voltage of the modelling lamp must correspond to the mains voltage. 2.2 Earthed mains Connect unit to current supply always using an earthed mains plug. 2.3 Start up In the proximity of the halogen lamp, the unit, depending on the accessories used, can acquire high temperatures. For this reason, we recommend to touch the unit only on the rear handle or on the stand adapter. Due to the intense heat radiation when a modelling light is in operation, keep the unit at a minimum distance of 1 meter from flammable surfaces. 1.) Remove the transparent plastic cap by turning and releasing the unlocking slide at the same time. Insert modelling lamp and flash tube as per instructions in chapter 8. Put on the protecting glass as well as the desired light shaper and turn in any direction. 2.) Please check that the mains supply corresponds to the information on the label of the unit. Connect unit to earthed mains. 6

3.) Switch on the unit with the mains switch (4). During charging, the digital flash energy display (17) flashes, afterwards the value is indicated continuously. Additionally the green control lamp of the ready display (7) is illuminated. 4.) Set the desired flash energy by means of the energy control keys “up / down“ (18). 5.) Switch IR-receiver, photocell or RFS-interface on or off depending on the exposure situation. 6.) If required, plug in synchronous cable in one of the sync sockets (6.1) or (6.2). 3. Energy control Use the „up/down“ keys (18) to control the flash energy (flash intensity) within a range of 4 f-stops. A value of 10 indicates maximum intensity, 6 the minimum. Whole numbers correspond to whole f-stops, decimal places to tenth f-stop steps. There is the option, to extend the control range up to 5 f-stops (see chapter 11), where in the underneath range a slightly higher exposure-tolerance has to be expected. Brief pressure on the energy control keys "up/down" (18) changes the setting by a 1/10 interval, prolonged pressure by 1/1 f-stop interval. The energy display (17) then flashes until charging or discharging have stabilized the new level of energy. 4. Modelling light 4.1 General The Minicom units are equipped with a halogen modelling lamp. The modelling light is switched on by the key “mod“ (5). When switched on, the green diode lights up. To protect the lamp filament from damage, it is advisable to switch off the modelling lamp when handling the compact unit. In chapter 7 you can find the instructions how to set the different operating modes (modelling light proportionality). Attention: The operating voltage of the modelling lamp must correspond to the mains voltage. 4.2 Proportionality The brightness of the modelling light can be set proportionally to the flash intensity. To assure proportionality also when units with different power output ratings are operated together, the units have various proportionality levels. Proportionality is guaranteed if the identical prop level has been set for all units. The higher the digit, the brighter the modelling light. The following operating modes are possible: “P“ This level can be set if either only Minicom 40 or only Minicom 80 are in use (most intense proportional modelling light). That means, the modelling light is proportional to the energy level 300J respectively 600J. 7

“P1“ Proportional modelling light with broncolor power packs rated 6400 J. “P2“ Proportional modelling light with broncolor power packs rated 3200 J. “P3“ Proportional modelling light with broncolor power packs rated 1600 J. “P4“ This proportionality level is optimised for an output level of 800 J. Recommended modelling light when using Minicom 80 in combination with Minicom 40. “P5“ If an unit is operated at a lower output level, the modelling light will be relatively weak and yellowish. To counteract this problem, the Minicom compact units are equipped with the additional modelling light proportionality level “P5“. It is optimised for the output level 400 J and less. Thus the brightness of the modelling light can be increased. “HI“ The unit operates at full modelling light, independent of flash output. “LO“ The unit operates at lower lighting level, independent of flash output, to reduce power consumption and extend the service life of the halogen lamps. Pressing the “mod“ key (5) for 1 second when the modelling light is on, will give direct access to the “HI“ mode. To return to the previous mode briefly press the “mod“ key. 4.3 Replacing the halogen lamps Before replacing the halogen lamp, it is essential to discharge the unit by flashes, immediately afterwards, disconnect it from the power supply. The halogen lamps are plug-in types. First the protecting glass has to be pulled off carefully in an axial direction (avoid tilting). The protecting glasses for the compact unit Minicom have a marking line and the glass rim has 2 grooves. When removing the protecting glass from the unit the marking line must be situated at the top. Taking into consideration the service life, the halogen lamp should not be touched with bare hands. To exchange the lamp, it must be pulled out of the plug socket in an axial direction. When inserting, ensure that the lamp is fully pushed back in. When engaging the protecting glass into the locking mechanism of the Minicom compact unit, the marking line must be situated at the top. After having engaged the protecting glass, it must be slightly turned, to prevent accidental loosening. 5. Release The flash release is enabled when 75% of the selected energy is available. Please note however , that the ready indicator is activated only at 100% charge (Kap. 6). The release is possible by means of a sync cable, infrared, photocell, or “test” key. When releasing via the photocell or the IR-receiver, ensure that the receiving cell of the unit is not obstructed by obstacles. 8

The appliance has a synchronous circuit with a low onload voltage to protect your camera contact. The synchronous circuit may not be connected in parallel with products of other manufacturers which operate with high synchronous voltage. 5.1 Photocell The photocell can be switched on or off by using the “cell“ key (1). If it is activated the green LED lights up. After a flash sequence, an active photocell will be blocked and the green LED blinks. By pressing the "cell" key, the photocell is reactivated. 5.2 Infrared receiver / RFS-interface (ir/rf) The IR receiver and, if available, the RFS interface can be switched on and off with the key „ir/rf“ (2). Optionally it can be established, if with this key, every time, both functions (IR and RFS) or just one of the two can be switched on or off (see chapter 11). Is one or both functions active, the green display lights up. 5.3 Infrared flash release channel The Minicom compact units can be released with broncolor infrared transmitters. When the unit is triggered via infrared, the flash release is effected with a time delay of 1/1000 s. The IR receiver integrated in the unit is used for a wireless release by with following units: - IRQ transmitter - IRX 2 transmitter - FCM 2 lightmeter and contrast photometer - FCC colour temperature measuring unit 5.4 Sync sockets The synchronous cables, art. no. 34.111.00 respectively 34.112.00, may be plugged into the sync sockets (1) or (2) to release flashes via cable 5.5 “Test“ key This „test“ key (7) allows manual release of the compact unit Minicom. The respective LED lights up when the flash voltage corresponds exactly to the selected value. During charging and discharging the LED goes out and the flash energy display (17) blinks. 6. Ready display visual /audible 6.1 The visual ready display is the green LED at the „test“ key (7). It lights up only when unit is at 100% charge. After releasing the flash this LED goes out until the unit is fully charged again. 6.2 The audible ready signal „buzzer“ sounds when the unit is at 100 % charged. It may be switched on or off (chapter 7). 9

6.3 Audible fault signal When the flash discharge fails, a warning signal of approx. 3 s duration will sound and the flash energy (17) of the compact unit will flash. 7. Setting additional functions The “aux“ key (10) is used to set the additional functions. With repeated actuation of the key the following modes can be selected: • Setting proportionality level of the modelling light LED “prop“ blinks (11) • Define sequence (serial flashes) LED “seq“ blinks (12) • Charging dimmer switch on / off LED “dim“ blinks (13) • Buzzer switch on / off LED “buz“ blinks (14) • Slow charge switch on / off LED “slow“ blinks (15) • Setting appliance address / studio address LED „unit“ blinks (16) • Return to standard display no LED blinks After the setting has been performed, the standard display can be re-activated by pressing the “aux“ key (10) or automatically after a waiting period of approx. 30 seconds. To select the additional functions and appliance settings, choose the respective LED (e.g. „charging dimmer switch on/off). The digital display (17) will then show the actual selected value which can be changed by the energy control keys „up/down“ (18). If a setting is entered which deviates from the standard setting value or a function is activated, the respective LED will remain lit as a reminder after the display returns to standard (exception: function “prop“). If the unit is switched off and on again , it will be in the “standard display” mode. Previously set additional functions are retained. 7.1 Setting proportionality level of the modelling light (prop) The proportionality level of the modelling light can be selected by briefly pressing the energy control keys „up/down“ (18). With repeated actuation of the key the following modes can be set, each shown respectively on the digital display (17): LO, P, P1, P2, P3, P4, P5, HI. 7.2 Sequence (serial flashes) (seq) This function allows to set a defined number of flash discharges from 1 to 50. By briefly pressing the energy control keys „up/down“ (18) the required number of flashes can be selected. 10

With a long pressure on the energy control keys “up/down”, the setting changes in intervals of ten. Each release signal triggers the selected number of flashes. A current sequence can be aborted by a long pressure on the energy control keys “up/down” or by switching off and on again the unit. The function is switched off, by setting the number of flashes to „0“. 7.3 Charging dimmer / boost function (dim) The „dim“ function can be switched on or off (on/--) by briefly pressing the energy control keys “up/down” (18). When switching on the “dim” function with the modelling light on (green LED of the “mod” key (5) lights up), the modelling light switches off while charging takes place. This feature allows visual flash control, to fade out the modelling light during flash sequences or to reduce the current load on weak mains. If the “dim” function is activated when the modelling light is switched off (green LED of the “mod” key (5) is off), the boost function will be activated. In this mode, the modelling light remains on as a visual flash monitor during charging. 7.4 Buzzer switch on/off (buz) The ready buzzer signals when the unit is at 100 % charge. The buzzer is switched on or off (on/--) by briefly pressing the energy control keys “up/down” (18). The warning signal also functions with the buzzer switched off. 7.5 Slow charge switch on/off (slow) In case of weak mains power supply lines, charging time may be extended to approx. double the standard value. The slow charge mode is switched on or off (on/--) by briefly pressing the energy control keys “up/down” (18). 7.6 Studio / appliance address (unit) The compact units Minicom are also available as versions with built-in RFS Interface (Radio Frequency System). For remote control respectively flash release via radio, an individual appliance address and a studio desk top (remote control channel) can be assigned to each RFS unit by means of the function “unit” (16). To carry out the settings, dial the LED „unit“ using the „aux“ key (10). The digital display (17) shows the letter “U”, followed by an appliance number between 1 and 8. By briefly pressing the energy control keys “up/down” (18), the required value can be selected. When pressing again the “aux” key, the digital display shows the letter “C”, followed by a studio number between 1 and 8. By briefly pressing the energy control keys “up/down”, the required value can be selected. 8. Flash tube The flash tube is coated to ensure an optimal colour temperature. For your security, only original flash tubes must be used. For safety reasons, never operate a unit without protecting glass in place. 11

8.1 Replacing the flash tube The flash tube is a plug-in type. To replace the flash tube, discharge the unit by flashes, disconnect it from power supply and let it cool off for ten minutes (to discharge the flash capacitors) 1.) The protecting glasses for the compact unit have a marking line and the rim of the glass has 2 grooves. When taking off the protecting glass of the unit the marking line must be situated at the top. Pull off the protecting glass carefully in an axial direction. (Avoid tilting). 2.) Press the spring radially inward and pull the flash tube out of the socket in an axial direction (do not touch the flash tube with bare hands) 3.) Insert the new flash tube and press the spring radially inward. When inserting ensure that the ceramic socket is fully pushed back in. The spring serves as well as contact and prevents accidental loosening of the flash tube. 4.) Replace the protecting glass. When engaging the protecting glass into the locking mechanism of the Minicom compact unit the marking line must be situated at the top. After having engaged the protecting glass it must be slightly turned to prevent accidental loosening. 5.) Connect the unit to the power supply, now it is ready for use again. 9. Protecting glass For safety reasons, never operate a unit without protecting glass in place. 10. Fuse The fuse (9) is located on the rear of the unit. Sand-filled fuses with value 3.15 AF may only be used (sand-filled fuses can be identified by their opaque fuse container). Using wrong fuses is dangerous; it may cause the halogen lamp to burst. Original broncolor replacement lamps are therefore delivered with the correct fuse. 11. Basic settings ex work The basic settings ex work can be viewed and in some instances changed with the following procedure: When the unit is switched on, simultaneously press the “mod” (5) and “aux” (10) keys for approx. 5 seconds (the LED array “prop” / “seq” / “dim” / “buz” / “slow” / “unit” blinks to indicate that you are in the programming mode). 12

Additionally the LED of the “mod” (5) key is lit. The digital display (17) shows the function number 0. The other function numbers can be selected by pressing the energy control keys “up/down” (18). By briefly pressing the “aux” key, the digital display shows the actual value respectively the actual setting within the selected function number. The LED of the “mod” key does not light up in this mode. Within the function numbers 1, 2, 3 and 9, the settings can be changed with the energy control keys “up/down”. Concerning the function numbers 0 and 4 – 8, the different pairs of these multiple digit values can be shown by means of the energy control keys “up/down”. Return to normal operation by pressing (1 s) the “aux” key, by switching the unit off and on again or automatically after a period of 20 seconds. Function number Meaning and possible settings 0 Program version: Standard display Program number: after pressing the energy control „down“ key 1 Control range flash energy: Setting ex work: "off" (--). Display "on" the control range of the flash energy is extended on to 5 f-stops (10 - 5.0). 2 Sensibility of the photocell: Setting ex work: "on" This function reduces the sensibility of the photocell. If the function is activated the digital display shows the value “off“. 3 Definition function „ir/rf“: Setting ex work: digital display shows the value "3" = IR receiver and RFS Interface (if available) activated. Display value “1“ = only IR receiver activated Display value “2“ = only RFS Interface activated. 4 Flash counter: Figure group in the display: xxxxXX = standard display Figure group in the display: xxXXxx = after pressing the energy control „up“ key Figure group in the display: XXxxxx = after pressing the energy control „up“ key 5 Series number of the unit: Figure group in the display: xxXX 6 Series number of the unit: Figure group in the display: XXxx 7 Production date of the unit: Figure group in the display: xxXX = month 8 Production date of the unit: Figure group in the display: XXxx = year 9 Reduction of the modelling light: Setting ex work: “off” (--) The activation of this function is recommended on power mains with great fluctuations. The voltage for the modelling lamp is reduced (light output ./. 1/3 f-stop), which results in a longer service life of the halogen lamp. If this function is activated, the digital display shows the value “on”. 13

12. Protective facilities / Fault indication 12.1 Cooling fan The cooling of flash tube, modelling lamp and internal electronics is effected by a cooling fan. It also runs when the modelling light is turned off. The cooling works on two levels, the fan runs smoothly when small flash sequences are effected. With longer flash sequences, the cooling fan switches to the higher level. 12.2 Display “th“ If excessively high temperatures build up inside despite the fan cooling, the charge mode will be blocked and a long audible signal will be generated. The modelling light is blocked as well for about 6 minutes. The digital display shows the indication “th” during the cooling period. The cooling process is accelerated by the fan which is still in operation. Attention: Do not switch off the unit during the cooling period! If the unit is switched off too early, only a small number of flashes can be effected until the next blockout, when switching on again the unit, despite a long break, because the processor could not completely pursue the cooling process. 12.3 Display “A1“ The unit is equipped with an automatic afterglow blockout. If the flash tube exhibits (e.g. at the end of its service life) afterglow, this blockout will block further charging to prevent consequential damage. This status is also discernible by the ready display, which is no longer green. The blockout can be cancelled by switching the unit off and on again. 12.4 Display “A2“ This indication is shown, when the unit is overcharging. Switch off the unit and switch it on again after a few minutes. If this fault continues to exist, please contact an after-sales service centre 12.5 Acoustic flash monitoring At the end of their service life, flash tubes often have triggering interruptions. This fault is indicated by an audible, intermittent signal. The signal disappears when the flash tube flashes properly again or the unit is switched off. 12.6 Monitoring of the modelling light If the compact units Minicom are connected to 200 V – 240 V mains voltage, after previously having been operated on 100 V - 120 V mains voltage, they will release an audible signal and the modelling light will blink at a safely reduced voltage. This function serves as a reminder that the modelling lamp must be exchanged, and also to protect against damage of the lamp. Switch the unit off and on again to return to standard operation. 14

13. Car battery converter If no mains power is available the 12 V-car battery converter can be used to charge the unit (only for 230 V units). The modelling light cannot be used in this operating mode (excessive load on the battery) and must be removed. • Switch off the modelling light and remove the halogen lamp • Connect the converter with the + and – connector clamps to the 12 V car battery. • Connect the unit to the converter and switch on the unit and the converter • Switch off the converter during pauses after flash work. Charge battery if needed by allowing the car engine to run. Two compact units Minicom can be connected to one converter. Approx. 200 flashes of 300 J respectively 100 flashes of 600 J are possible with a fully charged battery. 14. Mounting The stand adapter is located below the housing. The adapter is designed for standard broncolor® bolts (12 mm) and Manfrotto® pins (16 mm). Make sure the unit is firmly attached to the stand before operating. The click-stops of the locking handle can be adjusted by pulling it out. There are three possibilities for suspended mounting: a) b) c) The bracket of the compact unit is mounted upwards.

Attention: Read before starting up the compact unit: - Prior to replacing fuses, modelling lamp or flash tubes, discharge the unit anddisconnect it immediately from power supply. Prior to replacing the modelling lamp or flash tube, let the unit cool down for a period of 10 minutes. - The unit is designed for use in dry conditions. Protect it from water and fromexcessive exposure to dust. - The unit is not suitable for use in an environment where there is a risk of explosion. - The accessories mounted onto to the compact unit may heat up to hightemperatures under specific conditions. Handle with care. - With due allowance for heat radiation, units with more than 100 W modelling lightmay be directed against inflammable surfaces only at a minimum distance of 1meter. - For safety reasons, never operate the unit without protecting glass in place. - Flash light contains, similar to sunlight, a specific portion of UV light. Theundesirable side effects on skin and eyes are considerably reduced by using flashtubes and glass covers with an UV coating. Without these or other protectivefilters, use with extreme care when shooting. - Even when disconnected from the power supply, dangerous voltages may remain inside the unit. For this reason, units should be opened by authorized VISATECservice shops. - Do not block the cooling louvers on the unit. - Only fuses of the type indicated on the safety label may be used. This is especiallyimportant for the halogen lamp which can explode when used with the wrong fuse. Only use sand-filled fuses. They can be identified by their opaque fuse container. - 3 -

1. Application LOGOS We are very pleased you have chosen a VISATEC LOGOS compact unit which is a high-quality product in every respect. If used properly, it will render you many years of good service. This mains supplied studio flash is designed for professional photography. For your own safety, use a three-wire extension cable when required. 2. Start up 2.1 Mains voltage The compact units LOGOS 800 and LOGOS 1600 are available in two different versions: a) As a bi-voltage unit, of which the technical data are optimised for a mains voltage of 200 - 240 V. If this version is operated with a mains voltage of 100 – 120 V, a doubling of the charging time results. b) As an unit, which is exclusively designed for mains voltage of 100 - 120 V. 2.2 Earthed mains Connect unit to current supply always using an earthed mains plug. 2.3 Start up In the proximity of the halogen lamp, the unit, depending on the accessories used, can acquire high temperatures. For this reason, we recommend to touch the unit only on the handle at the rear or on the stand adapter. Due to the intense heat radiation when a modelling light is in operation, keep the unit at a minimum distance of 1 meter from flammable surfaces. 1.) Remove the grey plastic protecting cap by turning and releasing the unlocking slide at the same time. Insert modelling lamp and flash tube as per instructions in chapter 8. Put on the protecting glass as well as the desired light shaper and turn in any direction. 2.) Please check that the mains supply corresponds to the information on the label of the unit. Connect unit to earthed mains. 3.) Switch on the unit with the mains switch (9). During charging, the digital flash energy display (10) flashes, afterwards the value is indicated continuously. Additionally the green control lamp of the ready display (5) is illuminated. 4.) Set the desired flash energy by means of the energy control keys “up / down“ (8). 5.) Switch photocell (17) on or off, depending on the exposure situation. 6.) If required, plug in synchronous cable in one of the sync sockets (1) or (2). - 6 -

3. Energy control Use the „up / down“ keys (8) to control the flash energy (flash intensity) within a range of 4 f-stops. A value of 10 indicates maximum intensity, 6 the minimum. Whole numbers correspond to whole f-stop intervals, decimal places to tenth f-stop steps. Brief pressure on the energy control keys “up / down“ (8) changes the setting by a 1/10 interval, prolonged pressure by 1/1 f-stop interval. The energy display (10) then flashes until charging or discharging have stabilized the new level of energy. 4. Modelling light 4.1 General The LOGOS compact units are equipped with a very bright 150 W halogen modelling lamp. The modelling light is switched on by the key “mod“ (4). When switched on, the green diode lights up. In chapter 7 you can find the instructions how to set the different operating modes (modelling light proportionality). 4.2 Proportionality The brightness of the modelling light can be set proportionally to the flash intensity. To assure proportionality also when units with different power output ratings are operated together, the units have various proportionality levels. Proportionality is guaranteed if the identical prop level has been set for all units. The higher the digit, the brighter the modelling light. The proportionality levels of the LOGOS compact units are compatible with those of the broncolor units. The following operating modes are possible: “P“ This level can be set if either only LOGOS 800 or only LOGOS 1600 are in use (most intense proportional modelling light). That means, the modelling light is proportional to the energy level 300J respectively 600J. “P1“ weak proportional modelling light, applicable for all types of units “P2“ recommended modelling light when using LOGOS 1600 (also in combination with LOGOS 800) “P3“ recommended modelling light when using only LOGOS 800 “P4/5“ If an unit is operated at a lower output level, the modelling light will be relatively weak and yellowish. To counteract this problem, the LOGOS compact units are equipped with two additional modelling light proportionality levels: “P4“ for 150 J or less and “P5“ for 75 J or less. Thus the brightness of the modelling light can be increased. “HI“ The unit operates at full modelling light, independent of flash output. “LO“ The unit operates at lower lighting level, independent of flash output, to reduce power consumption and extend the service life of the halogen lamps. - 7 -

Pressing the “mod“ key (4) for 1 second when the modelling light is on, will give direct access to the “HI“ mode. To return to the previous mode briefly press the “mod“ key. The halogen lamp can be plugged in; when exchanging, do not touch the lamp with bare hands. Please note that the flash tube must be pulled out before exchanging the halogen lamp. 5. Release The flash release is enabled when 85 % of the selected energy is available. Please note, however, that the ready indicator is activated only at 100 % charge (chapter 6). The release is possible by means of a sync cable, photocell or the manual release key. 5.1 Photocell (cell) The photocell can be switched on or off by using the “cell“ key (3). If it is activated the green LED lights up. After a flash sequence, an active photocell will be blocked and the green LED blinks. By pressing the "cell" key, the photocell is reactivated. When releasing via the photocell, ensure that the receiving cell of the unit it not obstructed by obstacles. Because the photocell is also infrared-sensitive, the compact unit can be wirelessly released in a simple way by using a small flash unit with an infrared-permeable filter in front, mounted onto the camera. The VISATEC flash trigger is available under article number 56.200.00. 5.2 Sync sockets The synchronous cable, art. no. 54.104.00, may be plugged into the sync sockets (1) or (2) to release flashes via cable. The appliance has a synchronous circuit with a low onload voltage to preserve your camera contact. The synchronous circuit may not be connected in parallel with products of other manufacturers which operate with high synchronous voltage. 5.3 “Test“ key This “test“ key (5) allows manual release of the compact unit LOGOS. The respective LED lights up, when the flash voltage corresponds exactly to the selected value. During charging and discharging, the LED goes out and the output display blinks. 6. Ready display visual /audible 6.1 The visual ready display is the green LED at the “test“ key (5). It lights up only when the unit is at 100 % charge. After releasing the flash, this LED goes out until the unit is fully charged again. - 8 -

6.2 The audible ready signal „buzzer“ sounds when the unit is at 100 % charge. It may be switched on or off (chapter 7). 6.3 Audible fault signal When the flash discharge fails, a warning signal of approx. 3 s duration will sound and the display (10) of the compact unit will flash. 7. Setting additional functions The “aux“ key (11) is used to set the additional functions. With repeated actuation of the key the following modes can be selected: • Setting proportionality level of the modelling light LED “prop“ blinks (12) • Define sequence (serial flashes) LED “seq“ blinks (13) • Charging dimmer switch on / off LED “dim“ blinks (14) • Buzzer switch on / off LED “buz“ blinks (15) • Slow charge switch on / off LED “slow“ blinks (16) • Setting appliance address / studio address LED „unit“ blinks (18) • Return to standard display no LED blinks After the setting has been performed, the standard display can be re-activated by pressing the “aux“ key (11) or automatically after a waiting period of approx. 30 seconds. To select the additional functions and appliance settings, choose the respective LED (eg „charging dimmer switch on / off“). The digital display (10) will then show the actual selected value which can be changed by the energy control keys “up / down“ (8). If a setting is entered which deviates from the standard setting value or a function is activated, the respective LED will remain lit as a reminder after the display returns to standard (exception: functions “prop“ and “unit“). If the unit is switched off and on again, it will be in the „standard display“ mode. Previously set additional functions are retained. 7.1 Setting proportionality level of the modelling light (prop) The proportionality level of the modelling light can be selected by briefly pressing the energy control keys “up / down“ (8). With repeated actuation of the key the following modes can be set, each shown respectively on the digital display (10): P, P1, P2, P3, P4, P5, HI, LO. - 9 -

7.2 Sequence (serial flashes) (seq) This function allows to set a defined number of flash discharges from 1 to 50. By briefly pressing the energy control keys “up / down“ (8), the required number of flashes can be selected. With a long pressure on the energy control keys “up / down“ (8), the setting changes in intervals of ten. Each release signal triggers the selected number of flashes. A current sequence can be aborted by a long pressure on the energy control keys “up / down“ (8) or by switching off and on again the unit. 7.3 Charging dimmer / boost function (dim) The “dim“ function can be switched on or off (on/--) by briefly pressing the energy control keys “up / down“ (8). When switching on the “dim“ function with the modelling light on (green LED of the “mod“ key (4) lights up), the modelling light switches off while charging takes place. This feature allows visual flash control, to fade out the modelling light during flash sequences or to reduce the current load on weak mains. If the “dim“ function is activated when the modelling light is switched off (green LED of the “mod“ key (4) is off), the boost function will be activated. In this mode, the modelling light remains on as a visual flash monitor during charging. 7.4 Buzzer switch on / off (buz) The ready buzzer signals when the unit is at 100 % charge. The buzzer is switched on or off (on/--) by briefly pressing the energy control keys “up / down“ (8). The warning signal also functions with the buzzer switched off. 7.5 Slow charge switch on / off (slow) In case of weak mains power supply lines, charging time may be extended to approx. double the standard value. The slow charge mode is switched on or off (on/--) by briefly pressing the energy control keys “up / down“ (8). 7.6 Studio / appliance address (unit) The compact units LOGOS are also available as versions with built-in RFS Interface (Radio Frequency System). For remote control respectively flash release via radio, an individual appliance address and a studio desk top (remote control channel) can be assigned to each RFS unit by means of the function “unit“ (18). To carry out the settings, dial the LED „unit“ using the “aux“ key (11). The digital display (10) shows the letter “U“, followed by an appliance number between 1 and 8. By briefly pressing the energy control keys “up / down“ (8), the required value can be selected. When pressing again the “aux“ key (11), the digital display (10) shows the letter “C“, followed by a studio number between 1 and 8. By briefly pressing the energy control keys “up / down“ (8), the required value can be selected. - 10 -

8. Flash tube The flash tube is coated to ensure an optimal colour temperature. For your security, only original flash tubes must be used. For safety reasons, never operate a unit without protecting glass in place. If the compact unit LOGOS 800 is used for longer flash sequences, we recommend to employ the flash tube for LOGOS 1600 / SOLO 1600B - Art. no. 54.301.00. 8.1 Replacing the flash tube 1.) To replace the flash tube, discharge the unit by flashes, disconnect it from power supply and let it cool off for ten minutes (to discharge the flash capacitors). 2.) Remove the protecting glass. 3.) First pull out the ignition cable and then the flash tube (do not touch the flash tube with bare hands). 4.) Insert the new flash tube. 5.) Re-insert the ignition cable. 6.) Replace the protecting glass. 7.) Connect the unit to the power supply, now it is ready for use again. 9. Protecting glass For safety reasons, never operate a unit without protecting glass in place. 10. Fuse The fuse (7) is located on the rear of the unit. Sand-filled fuses with value 3.15 AF may only be used (sand-filled fuses can be identified by their opaque fuse container). Using wrong fuses is dangerous; it may cause the halogen lamp to burst. Original VISATEC replacement lamps are therefore delivered with the correct fuse. 11. Basic settings ex work The basic settings ex work can be viewed and in some instances changed with the following procedure: When the unit is switched on, simultaneously press the "mod" and "aux" keys for approx. 5 seconds (the LED array "prop" / “seq“ / "dim" / "buz" / “slow“ / "unit" blinks to indicate that you are in the programming mode). - 11 -

Additionally the LED of the „mod“ key is lit. The digital display shows the function number 0. The other function numbers can be selected by pressing the energy control keys “up / down“ (8). By briefly pressing the „aux“ key, the digital display shows the actual value respectively the actual setting within the selected function number. The LED of the „mod“ key does not light up in this mode. Within the function numbers 1 and 7, the settings can be changed with the energy control keys “up / down“ (8). Concerning the function numbers 0 and 2 – 6, the different pairs of these multiple digit values can be shown by means of the energy control keys “up / down“ (8). Return to normal operation by pressing (1 s) the „aux“ key, by switching the unit off and on again or automatically after a period of 20 seconds.

Important safety instructions When using your photographic equipment, basic safety precautions should always be followed, including the following: 1. Read and understand all instructions before using. 2. Close supervision is necessary when any appliance is used near children. Do not leave appliance unattended while in use. 3. Care must be taken as burns can occur from touching hot parts. 4. Do not operate appliance with a damaged cable or if the appliance has been dropped or damaged - until it has been examined by a qualified service person. 5. Position the cable so that it will not be tripped over, pulled, or contact hot surfaces. 6. If an extension cable is necessary, a cable with a current rating at least equal to that of the appliance should be used. Cables rated for less amperage than the appliance may overheat. When using a cable reel, it must be completely unrolled before use to prevent overheating of the cable. 7. When plugging in and unplugging lamp plugs, the unit must be switched off. 8. Always unplug appliance from electrical socket before cleaning and servicing and when not in use. Never jerk cable to pull the plug from the socket. Grasp plug and pull to disconnect. 9. Let appliance and connected lamp bases cool completely before putting away. 10. When putting away and winding up cables, take care they do not come into contact with hot parts of the appliance. 11. To reduce risk of electric shock, do not immerse this appliance in water or other liquids. 12. To reduce the risk of electric shock, do not open this appliance, but take it to a qualified service person when service or repair work is required. Incorrect reassembly can cause electric shock when the appliance is used subsequently. 13. The use of an accessory attachment not recommended by the manufacturer may cause a risk of fire, electric shock, or injury to persons. 14. Connect this appliance to a grounded socket. 2

Attention: Read before starting up the power pack - Prior to replacing fuses, light bulbs or flash tubes, discharge the power pack and disconnectfrom power supply. Disconnect the lamp base from the power pack. - These units are designed for use in dry conditions. Protect them from water and fromexcessive exposure to dust. - The units are not suitable for use in an environment where there is a risk of explosion. - The accessories mounted onto the lamp bases may heat up to high temperatures underspecific conditions. Handle with care! - With due allowance for heat radiation, lamp bases with more than 100 W modelling lightmay be directed against inflammable surfaces only at a minimum distance of 1 m. - For safety reasons, never operate the lamps without the protecting glassin place. - Flash light contains, similar to sunlight, a specific portion of UV light. The undesirable sideeffects on skin and eyes are considerably reduced by using flash tubes and glass covers with a UV coating. Without these or other protective filters, use with extreme care whenshooting. - Even when disconnected from the power supply, dangerous voltages may remain inside theunit. For this reason units should be opened by authorized broncolor service persons only. - Do not block the cooling louvers on the unit. - broncolor power packs and lamp bases meet an extremely high safety standard. Whenconnecting broncolor products to other manufacturers' products, integrated safety measures may become ineffective. Due to different design features and contact assignmentof the lamp plugs of other brands, the user himself/herself may even be at risk. We offer noguarantee and accept no liability for damages which may be caused by this type of usage. 3

1. Application Grafit A This mains (AC-line) supplied studio flash unit is designed for professional photography only. For your safety use a three-wire extension cable when required. 2. Start up 2.1 Mains voltage / voltage selector Set the unit to the required mains voltage by turning voltage switch (2) with a coin or screwdriver. The unit is designed for 230V, 120V or 100V according to voltage of country. If a different voltage than the original one is selected, the following limitations come into force: 230V unit on 120V: Can only be operated with power up to level 9. The charging time becomes longer. 120V unit on 230V: The recycling time becomes longer 100V unit on 230V: The recycling time becomes longer 2.2 Earthed Mains (AC-line) Connect unit to current supply always using earthed mains plug. 2.3 Start up Use the mains (AC-line) switch (1) to power-up unit. During the charging process the digital master power display (12) flashes, after which, it becomes continuous. 3. Energy control 3.1 Grafit A2/A4 Use the "+/-" keys (10) to control the flash energy (flash intensity) on both main outlets (I, II) within a range of 6 7/10 f-stops, and when including reserve lamp III within a range of 4 f-stops. A value of 10 in the display indicates maximum intensity, 3.3 resp. 6 minimum. Whole numbers are full f-stop intervals, decimals indicate 1/10 f-stop steps. Brief pressure on the "+/-" keys (7.1, 7.2, 7.3, 10) runs the power up (or down) by a 1/10 f-stop interval, prolonged pressure by a full f-stop. The display (12) then blinks until charging or discharging has stabilized the new level. 6

$3.2 1/10 or 1/3 f-stop increments control The fractional power level adjustment can be programmed for 1/10 or 1/3 f-stop intervals; the units are factory set to 1/10 steps. For reprogramming to 1/3 steps see chapter 7. 3.3 Individual energy distribution (Asymmetry) The Grafit A power packs incorporate a circuit for selectively distributing the power between the lamp base outlets. If outlet III is used as well, it has the highest flash energy. To ensure an optimum quality of colour temperature it is recommended to limit the maximum asymmetry of the flash power between each individual lamp outlet to three f-stops. The unit indicates this limitation if applicable. 4. Lamp base outlets Lamp base outlets of the Grafit units are marked with the Roman numerals I to III. All outlets may be switched individually (7.1, 7.2, 7.3). The LED (9) indicates the flash energy for each separate lamp base. For newly connected lamp bases, the connection will be automatically activated. 5. Modelling light 5.1 The "mod" key (16) switches on the modelling lamps for all connected lamp bases. When switched on, the green LED (Liquid Electronic Display) lights up. Lamp bases also have an additional modelling lamp switch. You may also operate the modelling light proportionally (Chapter 5.2) and adapt it to the various maximum outputs of broncolor power packs. 5.2 Proportionality In chapter 8 is an explanation of how to set the various operating modes (modelling light proportionality). Stages prop1, prop2, prop3, prop4 and prop5 are used to adapt the modelling light brightness of power packs with different output. The setting "modelling light proportional" duly allows for the output set, the number of lamp bases as well as an asymmetrical energy distribution. 7$
