Setup
1. Battery Installation
- Open the battery compartment cover located on the side of the flash unit.
- Insert four (4) AA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
2. Mounting on Camera
- Slide the flash's hot shoe onto your camera's hot shoe mount.
- Ensure the flash is fully seated.
- Rotate the locking pin (or locking ring) clockwise to secure the flash firmly to the camera. Do not overtighten.

Operating Modes
The NW635 offers several flash modes to suit various photographic needs.
Image: The flash's LCD display showing different operational modes: TTL, Multi (stroboscopic), and Slave S1, along with power settings and zoom.
1. TTL (Through-The-Lens) Mode
In TTL mode, the flash output is automatically controlled by the camera's light metering system. This provides balanced and accurate exposure by detecting the light bounced back from the subject. This mode is ideal for quick shooting and changing light conditions.
2. Manual (M) Mode
Manual mode allows you to set the flash output power manually, from 1/1 (full power) to 1/128 in 1/3 stop increments. This mode offers precise control over lighting and is suitable for consistent lighting setups or creative effects.

3. Multi (Stroboscopic) Mode
Multi mode allows the flash to fire a series of rapid flashes during a single exposure. This can be used to capture multiple images of a moving subject in one frame, creating a stroboscopic effect. You can adjust the flash frequency and number of flashes.
4. S1/S2 Slave Modes
These modes allow the NW635 to act as an optical slave flash, triggered by another flash unit. This is useful for off-camera lighting setups without the need for radio triggers.
- S1 Mode: The flash will fire in response to the first flash from a master flash. Suitable for manual flash setups.
- S2 Mode: The flash will ignore the pre-flash of a TTL master flash and fire on the main flash. Suitable for TTL flash setups where the master flash uses a pre-flash.

Flash Head Rotation
The flash head can be rotated and tilted to bounce light off ceilings or walls, creating softer, more natural illumination.
- Vertical Rotation: The flash head can tilt from -7 degrees to 90 degrees.
- Horizontal Rotation: The flash head can rotate from 90 degrees to 180 degrees.

LCD Display Functions
The LCD display provides essential information and allows for easy adjustment of settings.
- M/Multi Mode Indicator: Shows the current flash mode (Manual, Multi, or Stroboscopic).
- TTL Mode Indicator: Displays when TTL mode is active.
- Power Adjustment: Indicates the flash output level (e.g., 1/1 to 1/128).
- Slave Mode (S1/S2): Shows if the flash is operating as an optical slave.
- Sound Indicator Switch: Toggles the sound prompts.
- Flash Frequency Setting: Adjustable in Multi mode.
- Zoom Focal Length: Displays the current zoom setting (e.g., M 180mm).
- Overheating Protection: Icon indicates when the flash is overheating.
Advanced Features
1. Exposure Compensation
Adjust the flash exposure compensation from -3 to +3 in 1/3 stop increments to fine-tune the brightness of your subject relative to the background.
2. Zoom Function
The flash features an automatic or manual zoom function to match the focal length of your lens, ensuring optimal light coverage. The zoom range is typically from 24mm to 180mm.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the flash unit. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Do not use solvents or abrasive cleaners.
- Storage: When not in use for extended periods, remove the batteries to prevent leakage. Store the flash in a cool, dry place, away from direct sunlight and extreme temperatures.
- Flash Tube: Avoid touching the flash tube directly with bare hands, as oils can reduce its lifespan.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Flash does not fire. | Low or dead batteries; incorrect camera/flash settings; flash not securely mounted. | Replace batteries; check camera and flash settings (e.g., ensure flash is enabled); re-mount flash securely. |
| Flash exposure is inconsistent. | TTL metering issues with specific apertures; subject distance changes; flash head position. | Adjust flash exposure compensation; use manual mode for consistent output; ensure flash head is aimed correctly. |
| Flash gets stuck on camera hot shoe. | Overtightened locking mechanism; debris in hot shoe. | Do not overtighten the locking pin. Gently wiggle the flash while pulling it off. Clean the hot shoe contacts. |
| Flash overheats. | Frequent full-power flashes. | Allow the flash to cool down. Reduce flash power or frequency of firing. |
