Congratulations on your purchase of the Impact LiteTrek 4.0 Portable Monolight. Enjoy the many benefits of a portable strobe light, such as shooting on location or anywhere a portable compact lighting solution is required. The LiteTrek Portable Monolight was designed to work in conjunction with our power pack system. With a fully-charged power pack, you can achieve 650* flashes at full power, and 3500* flashes at the lowest power setting.

Assembly Attach the light stand mount to the bottom of the monolight using either one of the two counter-balancing holes. Tighten the thumbscrew on the light stand mount until it sits securely on the LiteTrek. 1 Loosen the stand mount knob and place the light onto a light stand with a 5/8˝ stud. Tighten the knob until the LiteTrek is secure on the light stand. 2 Adjust the tilt of the light by loosening the tension knob on the side and re-tighten when a suitable angle is found.
Attach the reflector by loosening the knob on the side of the reflector, and inserting the reflector so that the notches slide around the pins on the light head. Make certain that the hole for the umbrella shaft is positioned on the bottom of the reflector. 4 Twist the reflector clockwise until the pins are seated all the way into the notches, and then tighten the reflector locking knob to secure the reflector.
Assembly (continued) Make sure the power pack is turned off. Insert the power cable into the flash head power jack. 7 Plug the other end of the power cable into the power pack (outlet A). Outlet A on the Mini LT Power Pack is for connecting to the LiteTrek 4.0 Monolight. Outlet B is for connecting to compatible portable flash units. The Power Pack will not turn on unless a power cable is securely connected. This prevents the battery from discharging when the power pack is not in use.
Operating Instructions Turn the modeling light on for an indication of how the light will fall. The light will automatically shut off after 10 seconds in order to conserve battery power. 1 Set the power setting according to the required exposure by pressing the menu dial once, and then rotating the dial to the desired power settings.
Operating Instructions (continued) Wait for the monolight to recycle before the next picture is taken. An audible beep may sound when the monolight has fully recharged and ready to fire again. If the audible beep function has been turned off, a visual indicator on the top left of the LCD panel also indicates the recycle progress.
Quick Mode The monolight offers five levels of sync speeds in Quick Mode: FP, F2, F3, F4 and F5. FP, for “focal plane,” produces a succession of flashes at a very fast speed in order to illuminate the sensor as evenly as possible when shooting with fast shutter speeds (typically above 1/250s). This series of flashes is usually not noticeable with the naked eye. When using the FP settings, be aware that the flash will output at its lowest power setting to compensate for the fast burst speeds.
Multi Mode Multi Mode produces a series of continuous flashes for a single exposure. These pulses of light allow you to freeze several moments of action in a single image. This mode is great for sports or when capturing movement is critical.
1 Press the Menu Dial until the “QUICK” label is displayed, as well as the “CONT” label in the center of the screen. 3 Press the Menu Dial again. “MULTI” will be displayed below “CONT.” 2 Choose the desired interval speed between each pulse of light from 1-10 by rotating the Menu Dial. 4 Rotate the Menu Dial to select the amount of flashes that will fire in the sequence. Options are 5, 10, 15 and 20.
Audible Beep After every flash, the power needs to be recycled or recharged before the next flash can be fired. The LiteTrek Monolight provides a visual indicator at the top left corner of the LCD where a progress bar animates until the recycling is complete. An audible beep is sounded when the flash has finished recycling. To disable the beep, press the Menu Dial until only the speaker icon is shown.
Triggering the Monolight The simplest way to trigger the flash is to press the TEST button. This is useful when you need to discharge the power built up in the flash unit, for example just before replacing the flash tube (more on that later). The sync jack on the Monolight may be used for direct connection to a camera PC Sync connection. A radio slave receiver can also be plugged into this socket.
Flash Tube Replacement The charge in the flash unit must be discharged before removing the flash tube, or there is a risk of electrical shock. Make sure the flash unit is on. Push the TEST button on the rear panel of the flash. The unit will flash, discharging the power. Immediately turn off the power switch on the rear panel. Unplug the power cord from the power source. Never touch the flash tube immediately after use. Wait at least 30 minutes for the tube to cool down.
Modeling Lamp Replacement 1 Turn off and disconnect light from the power supply. Remove the reflector. 2 Using cotton gloves, gently lift and remove the modeling lamp from its socket. 3 Gently insert the new modeling lamp with firm and even pressure until it sits securely in the socket.
