User's Manual
Introduction
The Bolt RT-16 system allows you to control all compatible monolights and strobes from one convenient location with a reliable, easy-to-use controller.
The RT-16 is a great solution to speed up and simplify your workflow. Whether you work with a few flashes in a single setup, or in a large studio with a number of sets with many lights, you will immediately see the advantage of being able to make adjustments to your lighting without the need to maneuver into crowded, hard to reach places.
You can adjust the power level of each flash or group of flashes in 1/10 or 1/3 stop increments as well as controlling model lamps or AF assist lamps, turning alert sounds on or off and test firing and triggering your entire lighting setup, all from a central location. The RT-16 also features 16 channels to avoid interference and false triggers, along with the ability to address 16 separate groups for precision control of your lighting.

Using the RT-16
Installing Batteries in Transmitter
- Remove battery cover from unit.
- Insert two AA batteries, being sure to follow illustrations inside unit to properly position the positive (+) and negative (−) terminals.
- Replace battery cover.
Attaching the RT-16 Transmitter to Your
Camera: Rotate the locking wheel counterclockwise on the RT-16 until it is in the fully open (uppermost) position. You can also connect a PC cord from your camera to the unit's 3.5mm mini sync socket.
Attaching the RR-16-A Receiver to Your Compatible Flash or Monolight: Flip up
the USB connector on the RT-16 Receiver. Plug it into the USB port on your compatible flash or monolight.
Attaching the RR-16-B Receiver: Plug the connector pins into the appropriate socket on your compatible flash or monolight.
The receivers are powered directly from the flash or monolight, so no battery or external power is required. The Receivers have no On/Off switch. As soon as it is set and plugged in to an active, compatible flash or monolight, it will automatically begin to function.
Turning on the RT-16 Transmitter: To turn on the transmitter, slide the Power switch to the On position.
Setting the Channel: The RT-16 has 16 channels available for use. This allows you to avoid interference with other devices or photographers in a busy work environment, with each photographer operating on a different channel. Use the
DIP switches on the front panel of the transmitter and receiver to select the desired channel as shown on the DIP switch configuration chart.
In order for the transmitter and receiver to communicate with each other, both have to be set to the same channel.
Selecting the Group on the RT-16: Use the Group Select dial to choose the group you want to adjust. A group can consist of just one flash up to any number of flashes you wish. The Group function allows you to adjust settings on specific flashes or groups of flashes from one location, without having to go to each flash and make those adjustments individually.
Group-specific controls are raising and lowering the power, turning the sound on or off, and turning the modeling/AF assist light on or off.
Selecting the Group on the Receiver: Use the Group Select dial to choose the desired group.

Adjusting Power Output: Use the + and - buttons to adjust the power of the selected group up or down.
Using the RT-16
NOTE: The transmitter's display can be switched from showing power output in decimals (generally used for monolights) to fractions (typically used for flashes). To change this setting, press and hold the Set button until the display switches.
When the display is set to decimals, the power adjustments will be in 1/10th-stop increments. When set to fractions, the adjustments will be in 1/3rd-stop increments.
Sound: Use the Sound button to turn the sound on or off for all the flashes in the selected group. ▶ will be displayed on the LCD.
Lamp: Use the Lamp button to turn the Modeling or AF-Assist Light (depending on your device) on or off for all the flashes in the selected group. 🖼will be displayed on the LCD.
NOTE: The Sound and Lamp buttons will only work if your flash or monolight supports those functions.
Test: Press the Test button to test fire all flashes in all groups.
Turning Off a Group: To turn off a group, use the - button to turn its power down all the way. The display will indicate OF.
NOTE: After making any changes to settings, whether on the RT-16 or on any connected flashes, press the SET button to confirm and sync all settings. * will be displayed on the LCD.
Changes made to flash settings will be reflected on the RT-16 display, and on each flash's display as well.
The RT-16 can also be used as a handheld central remote controller to adjust the settings on all your compatible lights, even if you use a different method to actually trigger them (e.g. a sync cord, Pocket Wizard, etc.).
Troubleshooting
-
Unable to trigger a flash by pressing the Test button or the camera's shutter release:
-
Make sure the batteries are installed properly and the transmitter is powered on.
- Check the DIP switches to see that the transmitter and receiver are set to the same channel.
-
Check if the transmitter is firmly seated in the camera's hot shoe.
-
Signal disturbance or shooting interference (lights not firing or firing irregularly):
- Try using a different channel.
- Reduced operating range, or monolights not firing.
- Check if batteries in transmitter are drained. Try replacing with fresh ones.
-
Flashes not responding to adjustments made on transmitter.
-
Check that transmitter and receiver are set to the same channel.
