INSERTING THE BATTERIES
Remove the battery compartment cover 4 and insert four AA size batteries (prefer
ably the alkalinetype) or rechargeable(nickel cadmium) batteries inthe battery com"
partment.
Note: The batteries must be insertedwiththeir polarityas indicated within the battery
compartment. Incorrect insertionwill prevent proper operation of the flash unit.
Replace the battery compartment cover.
TESTING
To make sure that your flash unit isworking properly and that the batteries are not run
down, set switch 14 to the standby position, press the switch and wait till lamp 20
lights up. Then press test button 18.
CONNECTING THE FLASH UNIT TO YOUR CAMERA
Slide locking wedge 2 towards the rear of
the flash unit and slide mounting foot 1 into
the accessory shoe on the camera. Secure
the flash unit by sliding locking wedge 2 to-
wards the front of the unit.
If your camera has a hot shoe contact, the
flash unit has now been adapted complete-
ly to your camera.
If your camera does not have a hot shoe
contact, connection between camera and
flash unit should be made with the syn-
chronisation cable 26.
SETTING THE SHUTTER SPEED
Check the instructions for use of your camera, then set the shutter speed of your ca-
mera to the proper setting for use with an electronic flash, or use 1/30 second.
THE PHILIPS ENERGY SAVING SYSTEM
This electronic flash unit is fitted with the Philips Energy Saving System so that optimal
use is made of the batteries. Set switch 14to the standby position, press the switch
and the electronic flash unit starts to load. This is indicated by load indicator lamp 17.
After a period of time, loading is switched off automatically and the load indicator lamp
17 goes off. During loading, the indicator lamps 20, 21 and 22 light up one after the ot-
her and continue to be lit as long as there is sufficient electrical charge to make a flash
with the maximum of power. As the charge fades after auto switch off these indicators
extinguish one after another, showing the remaining power.
Lamps 20, 21 and 22 glow at full load 1/1.
Lamps 20 and 21 glow at three-quarter load 3/4.
Lamp 20 glows at half load 1/2.
If
the lamps 20, 21 and 22 are lit, the lower distance scale 12 should be used. This
scale is located at the same height as lamp 22 and shows the maximum distance
values at full load.Ifonly lamp 20 is lit, you should use the upper distance scale 12.
At half load (corresponding to indicator lamp 20) you only have half the distance you
have at full load. If the lamps 20 and 21 are lit, you have 3/4 of the maximum shown on
distance scale 12.
The flash unit reloads if you press switch 14 briefly. The flash unit reloads automatical-
ly after an exposure has been made.
When the batteries are run down or are no longer capable of loading the flash unit
completely, the available flash power is indicated by the indicator lamps 20,21 and 22.
These indicator lamps give a dear indication of the state of the batteries and therefore
make it possible to use batteries for longer and more economically than is the case
with flash units not using the ESS system. In addition, this electronic flash unit is fitted
with an energy-saving thyristor computer which conserves the remaining power from a
computer-controlled flash for the next flash and therefore creates a further saving in
battery consumption.

AUTOMATIC FLASH CONTROL
In automatic "computer" mode the light sensing cell 3 receives light reflected from
the central area of the subject and cuts off the flash when enough light has been re-
ceived.
It is necessary to set your camera lens aperture to match the one indicated on aper-
ture scale 9.
You have a choice of up to five different apertures with the P536 TCLS.
Both main and subflash light is regulated simultaneously. Select your filmspeed in
ASA scale 10, switch 14 to stand by selector 15 to positionAand switch 16 to AI,
A2, A3, A4 or AS. You will see a green lighted figure on the exposure scale 9.
For ASA 100 these figures will be 2.8, 4, 5.6 8 and 11 respectively.
Position A 1 has a range of 1.5 to 13 m. (5 to 43 feet)
Position A2 has a range of 1.0 to 9.0 m. (3.3 to 30 leet)
Position A3 has a range of 0.7 to 6.5 m. (2.3 to 21.5 feet)
Posn'oo A4 has a range of 0.7 to 4.5 m.
(2.3 to
15 feet)
Position AS has a range of 0.7 to 3.3 m. (2.3 to 10 feet)
When the subject is closer than 1.5 m (5 feet) it is advisable to select the wide angle
refractor andWsettings when using normal lenses.
Depending on the actual flash-to-object distance, a choice can be made between
these computer ranges. In general, the computer setting with the shorter distance
range (smallest aperture) should be selected to ensure the greatest depth of focus.
Set the correct film speed with the ASA sliding control 11 and select AI, A2, A3, A4
or AS. You will find the maximum distance for this computer range above the lit ex-
posure indication.
For ASA 80, you will find a green indication between two exposure values. This is
between 4 and 5.6 for position A3. You should then set the aperture of your camera
between 4 and 5.6. If this is not possible, aperture 4 should be selected.
Example: you are using a 100 ASA film and set the slider 11 accordingly. Ifyou se-
lect a computer range of between 0.7 m and 6.5 m (2.3 to 21.5 feet) (position A3).
you should select aperture 5.6 on your camera.
Note: If you have a "Flashmatic" camera (with a built-in flash control) you cannot
use automatic control but have to follow the instructions for MANUAL CON-
TROl.
AUTOMATIC FLASH RANGE CHECK
In order to be certain that the flash unit provides sufficient light to illuminate the sub-
ject correctly, you can make a triaillash.
This is done as follows: set the selector 15 to position A.
Then select A I, A2, A3, A4 or AS. Wait until the indicator lamps 20, 21 and 22 light
up and then press test button 18. If indicator lamp 19 lights up, there is sufficient
light for a good picture. You can also check this after an exposure. If indicator 19
does not glow, try position A I, or the one permitting largest camera lens aperture.
MANUAL FLASH CONTROL
In contrast with an automatic flash control, the flash unit gives the same quantity of
light under all circumstances in the M position. Set switch 14 to the standby positi-
on, press this switch and then set switch 15 to position M. Set switch 16 to position
1. Determine the distance to the subject and select the aperture setting on your ca-
mera corresponding to the distance and the film speed (ASA) as shown on aperture
scale
9.
Example: At a film speed of 100 ASA and a distance from the object to be photo-
graphed of 9 metres, the aperture of your camera should be set at f4.
A simple iormula is:
guide number
distance in metres
=
aperture (1 metre is approx. 1 yard)
Your flash unit has a guide number of 36. It makes negligable difference whether
the subflash is on or off.
Please remember that this is only the case when switch 16 is in position 1.
The 1/2, 1/4, 1/16 and 1/64 positions of switch 16 ensure that the flash unit produ-
ces a reduced but fixed quantity of light (power ratio). As compared with position 1
and at the same distance, you must open the aperture by one, two, four or six stops
further respectively.
This facility for selecting light quantities not only saves energy but also makes the
flash unit suitable for less usual flash exposures, e.g. for macrophotography or
when using a camera fitted with a winder or motor drive or in circumstances where
less light is desirable.
Example: You are using a 1.00 ASA film and set the flash unit accordingly. Set
switch 15 to position M. The distance to the subject IS 4.5 metres. When switch 16 is
in position I, aperture f8 should be selected. However, if you select position
1/2,
you should also select aperture f5.6. If you select position 1/16, you should use
aperture f2, given the same distance.
SHOOTING
Focus your camera and take the picture if the indicator lamps 20, 21 and 22 are lit.
FOR YOUR INFORMATION: 25 ASA = 15 DIN
50 ASA= 18 DIN
64 ASA = 19 DIN
80 ASA = 20 DIN
100 ASA = 21 DIN
125ASA=22DIN
200 ASA = 24 DIN
400 ASA = 27 DIN
BOUNCE FLASH
Bounce flash is recommended if you
want gentle diffuse lighting without prom-
inent shadows. Point the flashlight at the
ceiling (white for colour photography to
avoid undesirable colour variations in the
exposure). The reflector can be moved
through an angle of 180° to the left, 160°
to the right and 90° upwards.
The reflector can be moved upwards if
you rotate the rotating reflector control 6.
We recommend that you only make
bounce flashes exposures when the
computer is switched on (computer posi-
tion with the greatest distance range).
Ensure that the distance from the flash
unit via the reflective ceiling to the object
is not greater than the maximum permitted distance range of the computer. This
can be checked easily with computer ready lamp
19.
For manual bounce flash, the
aperture should be opened one stop further than indicated on the aperture scale on
the unit for direct flash. For example: f4 instead of f5.6 at a reflector position of 45°. If
the reflector is in a position between 60° and 90°, the aperture should be opened
two stops more, i.e. f4 instead of f8. Clearly, this whole process depends to a cer-
tain extent on the type of wall or ceiling. The corrective action mentioned above
should only be used in normal situations (white ceiling or wall).
Diffuse light can also obtained with the Philips accessory, bounce panel PFB 507.
SUBFLASH
Some situations require a combination of direct and indirect flashlighting, e.g. por-
trait photography. These are combined perfectly in this flash unit.
The main flash can be rotated in all directions to provide indirect lighting for an ob-
ject via a wall, ceiling or other reflective surface, whilst the subflash is pointed di-
rectly at the object. Use of this subflash softens shadows on the object.
The subflash is switched on and off with switch 25.
At full power it has a guide number of 9, if the main flash is not directed at the sub-
ject.
WIDE ANGLE - NORMAL -,TELE SETTING
The light beam of the flash unit can be widened or narrowed with the built-in wide
angle diffuser or tele refractor in the flash unit. These can be used to modify the light
beam from your flash unit to the various lenses of your camera. The indications
W,
Nand T are located on the side of the unit.
W means wide angle and is for use with wide angle lenses from 28 mm to 50 mm.
N means normal and is for use with lenses with a focal length from 50 mm to 135
mm.
T means tele and is for use with tele lenses from 135 mm and longer.
The wide angle diffuser or tele refractor can be positioned in front of the reflector by
means of rotating control 7.
If the reflector is rotated, the selected light beam setting is also rotated.
The W-N-T sliding control 13 should be set in a position which corresponds to the
beam setting in use. The corrected maximum distance to the subject can then be
read off normally from the distance scale 12.
USING COLOUR FILTERS
The light beam can be coloured with the colour iilters supplied.
These filters should be inserted in the colour filter compartment 8.
The colour filters can also be used in combination with the tele refractor or the wide
angle diffuser. .
Clearly, the use of colour filters affects the lighting. The aperture should then be set
approx. 1 to 1.5 stops further open.
HINTS AND PRECAUTIONS
Flash units are not only used in photography when ordinary lighting is insufficient
but can also be used when lighting is normal in order to prevent shadows appearing
in the final exposure. You can read books on this subject but the most important
thing is to experiment with your camera and flash unit until you have discovered all
the possibilities. By using the slave unit P 100-SU (available separately), you can
use several flash units simultaneously.
Power pack PFB 104 (available separately) can be used to shorten the interval be-
tween two flashes to approx. 4 sec. for manual control and between 0.5 sec and
4
sec for automatic control.
The power pack can be connected to your flash unit via connection
23.
The power
pack is extremely useful with a camera fitted with a winder or motor drive.
When taking pictures with flash, do not shoot directly at highly reflective surfaces li-
ke-mirrors or windows. When you have finished a session of flash photography, set
switch14to the off position.
Remove the batteries when the flash unit is not to be used for some time.
Do not try to open or repair your flash unit. This not only voids the guarantee but
could be dangerous because of the high voltage present.
If your flash unit needs repairing or does not work correctly, take it back to your
dealer.
