The DRT-4G Radio Trigger System is
designed for photographic studios and on-location work to
trigger various flash lights and strobes. The DRT-4G has
four channels. The standard pack is composed of one Radio
Trigger and one self-locking Radio Receiver. Since it has
multiple channels, the triggering delay is 1/6000 second and
can satisfy the synchronous flashlight request of various
shutters.
Features
Micro-computer control.
1/6000 second Triggering delay.
Multiple channels which work
without interference of each other.
Receiver searches for channel
automatically.
Receiver has LED indicator light.
Long lifetime of internal transmitter battery-
over 20,000 continuous triggers.
Receiver uses two AAA batteries
(lifetime varies).
Receiver comes with various sync
cord adapters for different strobes.
Small and stylish.
Operation
Insert 2 AAA batteries into the DRT Receiver in correct +/- direction. (Your DRT
Trigger comes with a pre-installed 23A battery.)
2. Connect DRT Receiver with your strobe using the
included adapter. Press the power switch of the DRT
Receiver.
Press the test button on the DRT Trigger. You
should see the LED on th DRT Receiver twinkling and your
strobe flashing. It means that the DRT has locked one
channel and is prepared to work.
3.To change the Channel you need to slide the
channel switch of DRT Trigger and press the power switch
twice to reset the DRT Receiver.
Receive step 3 to lock the channel.
Install your DRT Trigger on the hot-shoe plate of
your camera. Or connect the DRT Trigger with your
camera using included sync cord.
The DRT may work with more than on Trigger or
Receiver.
You can switch the power switch off to increase
lifetime of batteries.
It is time to change the batteries for your DRT
Radio Trigger System when there is missing triggering or
self triggering.
Uninstall the batteries of DRT Receiver if you will
not use it for a long time.
TROUBLESHOOTING YOUR RADIO
TRIGGER DEVICE
If you receive your radio trigger
(transmitter/receiver) system and it does not
function properly, please read the following before
contacting us:
Make sure there are good batteries in the
receiver. A fresh set of AAA alkaline
batteries are recommended. Make sure the
batteries are oriented in the receiver's
compartment correctly and that there is no
damage, corrosion or rust in the battery
compartment. Misfiring and self triggering
are a sign of faulty, low charge/dying
batteries.
Make sure your camera is set to the
appropriate setting to allow for an external
triggering device. Some cameras may
require extra setup for use with external
flash/strobe devices- please see your camera's
literature.
For best results keep the line of sight
between the transmitter and receiver. If
this is not possible, keep the units away from
objects that may absorb, block or in anyway
interfere with radio signals. Because this
system works with low frequency radio signals,
you may find interference or dead spots which
may prohibit the triggering device from
functioning properly. If this is the case, move
the location of the devices until proper
functionality is restored. Interference
and/or dead spots are cause by a number of
things and the easiest and best solution is
moving.
Some strobes may emit low frequency signals
that can trigger the receiver causing the strobe
to flash intermittently. If this is the
case, move the receiver at least 12 inches from
the strobe with an extension cable (a common
audio headphone extender cable). If using
multiple receivers, keep them at least 2 to 3
feet from each other.
If the radio trigger device does not fire
the strobe into which the receiver is connected,
follow the advice above. If it still fails
to function properly, try it on a
different strobe. It may be the strobe
unit.
To ensure continued reliability of usage, do not
drop or expose either unit to moisture or extreme
temperatures. Remove batteries when not in
use.
