SPECIFICATIONS

The macro twin flash kit provides flexible lighting for macro nature photography. It is ideal for close-up photography of flowers, insects, small objects,

and so on.

• Freedom to change the attachment position and angle of the flashtube enables more expressive photography.

• Attaching two-length adjustable arms between the twin flash units and holders makes it possible to change the lighting for high magnification

close-up photography.

• Using the supplied diffuser enables softer lighting.

• The supplied wide panel expands flash coverage to a focal length of 24 mm.

• Modeling flash function can check shadows before photographing.

1. SERVICE NOTE

1-1. Chemicals

Some chemicals used for servicing are highly volatile.

Their evaporation caused by improper management affects your health and environment, and wastes resources.

Manage the chemicals carefully as follows.

•Store chemicals sealed in a specific place to prevent from exposure to high temperature or direct sunlight.

•Avoid dividing chemicals into excessive numbers of small containers to reduce natural evaporation.

•Keep containers sealed to avoid natural evaporation when chemicals are not in use.

•Avoid using chemicals as much as possible. When using chemicals, divide only required amount to a small plate from the container and

use up it.

1-2. Exterior Parts

Be careful to the following points for exterior parts used in this unit.

•Use a piece of cleaning paper or cleaning cloth for cleaning exterior parts. Avoid using chemicals.

Even if you have to use chemicals to clean heavy dirt, don’t use paint thinner, ketone, nor alcohol.

•Insert the specific screws vertically to the part when installing a exterior part.

Be careful not to tighten screws too much.

1-3. Unleaded Solder

This unit uses unleaded solder.

Boards requiring use of unleaded solder are printed with the lead free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)

: LEAD FREE MARK

Be careful to the following points to solder or unsolder.

•Set the soldering iron tip temperature to 350 °C approximately.

If cannot control temperature, solder/unsolder at high temperature for a short time.

Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful!

Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges

occur such as on IC pins, etc.

•Be sure to control soldering iron tips used for unleaded solder and those for leaded solder so they are managed separately. Mixing

unleaded solder and leaded solder will cause detachment phenomenon.

1-4. SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer.

1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and

bridges.

2. Check the interboard wiring to ensure that no wires are “pinched”or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the

customer and recommend their replacement.

4. Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend their

replacement.

5. Check the B+ voltage to see it is at the values specified.

6. Flexible Circuit Board Repairing

•Keep the temperature of the soldering iron around 270 °C during repairing.

•Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

•Be careful not to apply force on the conductor when soldering or unsoldering.

2. DISASSEMBLY

Cut and remove the part of gilt

which comes off at the point.

(Be careful or some

pieces of gilt may be left inside)

NOTE FOR REPAIR

•Make sure that the flat cable and flexible board are not cracked of bent at the terminal.

Do not insert the cable insufficiently nor crookedly.

•When remove a connector, dont’pull at wire of connector. It is possible that a wire is snapped.

•When installing a connector, dont’press down at wire of connector.

It is possible that a wire is snapped.

•Do not apply excessive load to the gilded flexible board.

DISCHARGING OF THE CHARGING CAPACITOR ONTHE PC BOARD SET, D

The charging capacitor of the PC board set, D is charged up to

the maximum 330 V potential.

There is a danger of electric shock by this high voltage when the

capacitor is handled by hand. The electric shock is caused by

the charged voltage which is kept without discharging when the

main power of the unit is simply turned off. Therefore, the

remaining voltage must be discharged as described below.

Preparing the Short Jig

To preparing the short jig, a wire is attached to each end of a

resistor of 1 kΩ/1 W (1-215-869-11).

Wrap insulating tape fully around the leads of the resistor to

prevent electrical shock.

1 kΩ/1 W

Wrap insulating tape.

R:1 kΩ/1 W

(Part code: 1-215-869-11)

Note: High-voltage cautions

Discharging the Capacitor

Short-circuit between the two points

with the short jig about 10 seconds.

Do both A and B.
