Using the Flash
1. Power Management
ON/OFF Power Switch (19) controls the on-and-off of the flash unit. Turn off the
power pack if the flash unit will not be used for an extended period of time.
2. Flash Output
Flash output can be varied from 1/128th power to 1/1 full power in 1/3 stop
increments. To obtain a correct flash exposure, use a hand-held flash meter to
determine the required flash output.
Adjust the power output by rotating Select Dial (21). The following table makes it
easier to see how the stop changes in terms of f/stop when you increase or
decrease the flash output:

OF
When “OF” is shown on the LCD display, it means no flash output and flash firing is
turned off.
3. M Mode: Manual Mode
Press MODE Selection Button (17) to enter M mode. In this mode, you can set the
flash unit onto your camera hot shoe or your trigger hot shoe for firing. Before
shooting, adjust the power output of CL-180. When the camera’s shutter is pressed,
the flash will fire. Slave triggering mode is not available in M mode.
4. S1 Mode: S1 Slave Triggering Mode
Press Mode Selection Button (17) to enter S1 mode. In this mode, the flash unit can
function as a slave flash for creating multiple lighting effects. It is respectively
applicable to manual flash environment.
In S1 mode, the flash unit will fire synchronously when the master flash fires, the
same effect as that by the use of radio triggers.
5. S2 Mode: S2 Slave Triggering Mode
Press Mode Selection Button (17) to enter S2 mode. In this mode, the flash unit can
function as a slave flash for creating multiple lighting effects. It is applicable when
using a TTL master flash.
In S2 mode, the flash unit will ignore a single “preflash”from the master flash and will
only fire in response to the second, actual flash from the master.
6. RPT Mode: Stroboscopic Flash
Press Mode Selection Button (17) to enter RPT 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 second. expressed as Hz),
the number of flashes, and the flash output.
For setting procedures, see the following:
Press the Mode Selection Button (17) so that “RPT” is displayed.
Press Set Button (18) to select the item to be set. The item blinks.
Rotate Select Dial (21) to set a desired number.
Calculating the Shutter Speed
During stroboscopic flash, the shutter remains open until the firing stops. Use the
following formula to calculate the shutter speed required to capture the full sequence
of flashes:
Number of flashes / Firing 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 sec.
Note:
Stroboscopic flash is most effective with a highly reflective subject against a dark
background.
Using a tripod, a remote switch, and an external power source is recommended.
NOTICE ! A flash output of 1/1 or 1/2 cannot be set for stroboscopic flash.
- 07 - - 08 -
Stroboscopic flash CAN be used with “bulb” setting.
To avoid overheating and deteriorating the flash head, do not use stroboscopic flash
more than 10 times in succession.

7. Hi-Speed Sync Triggering
To enter mode, press both Mode Selection Button (19) and Set Button (20).
Press Mode Selection Button (17) again to exit mode.
In hi-speed sync triggering mode, you can use a hi-speed sync trigger to have
your flash unit synchronize with all shutter speeds of cameras.
This is convenient when you want to use aperture- priority for
fill-flash portraits.
Note:
Hi-speed sync triggering mode is effective only when the
flash unit is used together with hi-speed sync trigger, e.g.,
Cells II transceiver.(sold separately)
Hi-speed sync triggering mode is NOT available when the flash unit is mounted
onto the camera hotshoe.
To avoid overheating or deteriorating the flash head, the High-Temperature Protection
function will be activated automatically after 10 continuous high-speed flashes and the
recycle time becomes 10s longer.

8. MF-Assist Beam
Under poorly-lit or low-contrast conditions, you can press MF-Assist Beam Button
(15) to turn on the MF-assist beam in order to make it easier to autofocus.
When the MF-assist beam is lit, is shown on the LCD display.
9. Buzz Function
The buzz function can be controlled by pressing BUZZ Button (16).
When the buzzer is turned on, is shown on the LCD display. The buzzer provides
an indication that CL-180 flash unit has fully recycled.
10. Wireless Control Function
The flash unit is built in with a Wireless Control Port (7) so that you can wirelessly
control the on-and-off of your flash, modeling lamp and buzzer, as well as adjust the
flash output level, etc.
To control the flash wirelessly, you need a Cheetah CL series remote control set
(CL-Tx and CL-Rx). Insert CL-Rx receive into the Wireless Control Port (7) on the
flash and put CL-Tx transmitter on top of the camera hot shoe. Settings made on
the CL-Tx transmitter , and CL-Rx receiver will be wirelessly communicated to the
flash. Then you can press the camera shutter-release button to trigger the flash.
For full instructions on the use of CL series remote control, see its user manual.
When the flash unit receives wireless signals, is shown on the LCD display.
11. Sync Triggering
The Sync Cord Jack (8) is a 3.5mm plug. Insert a trigger plug here and the flash will
be fired synchronously with the camera shutter.
12. PC Sync Triggering
Insert one end of a PC sync cable into the PC Sync Socket (9) of the flash unit and
the other end into the PC Sync Socket on the camera. The flash unit will fire when
the camera’s shutter-release button is pressed.

Protection Function
High-Temperature Protection
To avoid overheating and deteriorating the flash head, do not fire more than 75
continuous flashes in fast succession at 1/1 full power. After 75 continuous flashes,
allow a rest time of at least 10 minutes.
If you fire more than 75 continuous flashes at 1/1 full power and then fire more
flashes in short intervals, the High-Temperature Protection function may be activated
and make the recycling time about 10 to 15 seconds. If this occurs, allow a rest time
of about 10 minutes, and the flash unit will then return to normal.
When the High-Temperature Protection is started, is shown on the LCD display.
