Thank you for purchasing a Canon product.

The Canon Extender RF1.4x and Extender RF2x increase the focal

length of the attached RF lens by 1.4x and 2x respectively.

When Extender RF1.4x is attached, the lens maximum aperture will be

smaller (darker) by 1 stop. With Extender RF2x, the maximum aperture

will be smaller by 2 stops. In any case, the camera will compensate the

exposure automatically.

Caution Details pertaining to risks that may result in injury or

damage to other objects.

● Do not leave the product in places exposed to extremely high

or low temperatures. The product may cause burns or injury when

touched.

This device complies with Part 15 of the FCC Rules. Operation is subject to the

following two conditions: (1) This device may not cause harmful interference, and (2)

this device must accept any interference received, including interference that may

cause undesired operation.

Do not make any changes or modifications to the equipment unless otherwise

specified in the instructions. If such changes or modifications should be made, you

could be required to stop operation of the equipment.

This equipment has been tested and found to comply with the limits for a class

B digital device, pursuant to part 15 of the FCC Rules. These limits are designed

to provide reasonable protection against harmful interference in a residential

installation. This equipment generates, uses and can radiate radio frequency

energy and, if not installed and used in accordance with the instructions, may cause

harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular

installation. If this equipment does cause harmful interference to radio or television

reception, which can be determined by turning the equipment off and on, the user

is encouraged to try to correct the interference by one or more of the following

measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

■ Attaching and Detaching the Extender

First attach the Extender to the lens, then attach it to the camera.

To detach it, follow the same procedure in reverse.

To detach the Extender from the lens, slide the lens release lever and

then turn the Extender counterclockwise.

■ Safety Precaution

z Do not leave the product in excessive heat such as in a car in direct

sunlight. High temperatures can cause the product to malfunction.

z You cannot attach two or more Extenders on the same camera.

z The rear mount on the Extender has been fitted with a rubber ring

to improve dust-resistance and water-resistance performance. This

rubber ring may cause friction marks to appear around the camera’s

lens mount, although this will have no effect on usage. Rubber rings

can be replaced at Canon Service Center (chargeable).

z Using the Extender may limit the minimum shooting length possible

according to the product’s specifications.

z Autofocusing slows down when the lens is used with the Extender, in

order to maintain the precision of autofocus control.
