Notes of the speaker as the history default status. If you use the commercially available screws, use the screws that matches to the following specifications:

Screw type....M8 Screw length....35 mm (1 3/8") or more

Caution

• The required length of a screw differs depending on the mounting bracket to be used. Select a screw which is suitable for use with the mounting bracket and can be fully inserted into the hole on the speaker.
• As this product is heavy, do not attach them to thin plywoods or soft wall surface materials, as the screws may tear free from flimsy surfaces, causing the speaker to fall and be damaged, or result in personal injury.
• Do not fasten the speaker to the ceiling with nails, adhesives, or other unsound hardware. Long-term use and vibrations may cause them to pull free.
• To avoid accidents resulting from tripping over loose speaker cables, fix these to the wall along with the speaker.

■ When connecting the speaker cables

Notice

• Do not let the bare speaker wires touch each other as this could damage the speaker or the amplifier.
• Make sure you connect the speakers with the correct polarity—positive (+) terminals to positive (+) terminals, and negative (-) terminals to negative (-) terminals. If you get them crossed over, the sound will be unnatural and lack bass.
• Refer to the owner's manual that came with your amplifier.

■ How to connect the speaker cables

1. Remove 10mm (3/8") of insulation, and twist the bare wires.
2. Loosen the terminal knob.
3. Insert the bare wire into the hole.

Note

Do not insert the insulation into the hole. Sound may not be produced.
4. Tighten the knob and secure the cable. 5. Test the firmness of the connection by pulling lightly.

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated placeholder underscores where none should exist in the GT. Hence, the OCR result is inconsistent with the Ground Truth.
