Frequently Asked Questions - ET-D75LE10 PANASONIC

Which projectors are compatible with the Panasonic ET-D75LE10 lens?

The ET-D75LE10 is designed for use with Panasonic PT-DZ870, PT-DS850, and PT-DW830 series projectors. Always check your projector's lens compatibility chart before purchase.

How do I install the ET-D75LE10 lens?

Turn off the projector and remove the existing lens cap. Align the lens mount with the projector's lens bayonet, gently push in, and rotate until it clicks into place. Ensure it is securely locked before turning on the projector.

Can I use this lens with projectors from other brands?

No, the ET-D75LE10 uses a proprietary Panasonic bayonet mount and is only compatible with select Panasonic projectors. Using it with other brands may damage the lens or projector.

What is the zoom range of the ET-D75LE10?

The lens offers a 1.2x zoom ratio with a focal length range of 36.7 mm to 44.0 mm, providing flexibility in image size without moving the projector.

Is the zoom and focus motorized?

Yes, both zoom and focus are motorized and can be controlled via the projector's remote control or on-screen menu, allowing precise adjustments from a distance.

How should I clean the ET-D75LE10 lens?

Use a dry, soft microfiber cloth to gently wipe the lens surface in a circular motion. For stubborn smudges, use a lens cleaning solution applied to the cloth, not directly on the lens.

What is the throw ratio of this lens?

The throw ratio depends on the projector model and screen size. For example, with a 100-inch screen, the throw distance ranges approximately from 2.5 to 3.0 meters. Refer to the projector manual for precise calculations.

Does the ET-D75LE10 support 4K resolution?

While the lens itself does not limit resolution, it is designed to work with projectors that support up to WUXGA (1920x1200). For 4K, ensure the projector natively supports 4K and the lens is optically compatible.

What is the weight of the ET-D75LE10?

The lens weighs approximately 1.1 kg (2.4 lbs), making it relatively lightweight for a motorized zoom lens.

Where can I find replacement parts or accessories for this lens?

Replacement parts such as lens caps are available from authorized Panasonic dealers or online retailers. For repairs, contact Panasonic support or a certified service center.

• Place a stepping motor unit and DC motor unit that will not be used in this product's packaging box together with the screws, and store the packaging box in a safe place.
• When disposing of the packaging, dispose of it appropriately.

Attaching / Detaching

Before attaching the stepping motor unit

• Detach the projection lens from the projector before carrying out this work. (For details on attaching and detaching the projection lens, refer to the operating instructions of the projector.)
• Remove the DC motor unit from the projection lens before attaching the stepping motor unit.

Attention

● Perform the attaching and detaching work in a clean environment.
- Before carrying out the work, attach the supplied lens cover, etc. to the projection lens so that the lens surface does not get fingerprints or dirt on it or become scratched.
- Employ certified personnel to perform the attaching and detaching work.
- The attaching and detaching work must be carried out by two persons. One person should hold the lens while the other person performs the work to exchange the motor unit.
● Perform this work on soft material on a flat surface.
- When tightening the screws, use a torque driver. Do not use an electric screwdriver or impact driver.

Attaching / Detaching (Continued)

Do not touch the switches of this product and the removed DC motor unit because there is a risk of damaging them.

Detaching the DC motor unit

Attention

- Check that the retaining screw does not protrude over a gear. If it does protrude over a gear as shown in the figure, you will not be able to detach the DC motor unit. In that case, attach the lens to the projector and perform the zoom operation to move the position of the retaining screw.

1) Remove the one fixing screw (M3 x 10 mm) from the cover.

Attention

- Screw locking agent is applied to the screw. Take care that it does not enter in between gears during removal.

4) Place the lens upside down.

- When the lens is turned upside down, one person should hold the DC motor unit so that it does not become detached and fall.

Note

- If the DC motor unit is detached without turning the lens upside down, a gear of the DC motor unit may fall off.

5) Remove the DC motor unit by pulling it down in a diagonal direction.

Attaching / Detaching (Continued)

Supplied screws with captive washers (M3 x 10 mm)

3) Fix the stepping motor unit with the two supplied screws with captive washers (M3 x 10 mm) in the order ① and ② shown in the figure.

● Tighten the screws to a torque of 0.6 to 0.8 N·m.

Detaching the stepping motor unit

Detach the stepping motor unit by performing the procedure to attach the stepping motor unit in reverse.

* If the DC motor unit will be used again, attach it as described in "Attaching the DC motor unit" below.

Attaching the DC motor unit

Pure mechanical assembly diagram without any text, numbers, or symbols

1) Lower the gears of the DC motor unit to the end of the shaft.

- Hold the lowered gears so that they do not come off the shaft and fall.

Attaching / Detaching (Continued)

2) Hold the DC motor unit level and engage the lower gear with the gear on the lens side and insert the shaft into the shaft hole while inserting the large upper gear into the groove in the lens.

- If the gears have not been lowered to the end of the shaft, the gears will not engage because the shaft will contact the lens. If that happens, raise the DC motor unit until the shaft no longer contacts the lens and then engage the gears while pushing the DC motor unit in.

- If gear engagement is offset to the left or right, the shaft will not be able to be inserted in the shaft hole, so make adjustments using the left and right screw stop hole positions as a guide.

Attention

● Make sure that screw locking agent does not enter in between gears during attachment.

3) Fix the DC motor unit with the fixing screw (M3 x 6 mm).

- Use the screw that was removed in step 3) of "Detaching the DC motor unit" (page 7).

● Tighten the screw to a torque of 0.6 to 0.8 N·m.

Attention

- Remove the screw locking agent applied to the fixing screw before use.

5) Fix the cover with the fixing screw (M3 x 10 mm).

• Use the screw that was removed in step 1) of "Detaching the DC motor unit" (page 6).
  ● Tighten the screw to a torque of 0.6 to 0.8 N·m.

Attention

- Remove the screw locking agent applied to the fixing screw before use.
