• Do not mount the unit in locations exposed to constant vibration. The mounting bracket can be damaged by excessive vibration, potentially causing the unit to fall, which could result in personal injury.
• Do not use anti-rust lubricant. If it contacts resin or rubber parts, they could deteriorate and cause the unit to fall, possibly resulting in personal injury.
• Avoid installing the speaker in locations close to the seashore or in indoor swimming facilities that are not well ventilated. In such locations, the bracket may be vulnerable to corrosion, eventually allowing the speaker to fall resulting in personal injury.

CAUTION Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

• To avoid electric shocks, be sure to switch off the unit’s power when connecting speakers.
• Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.
• Do not operate the unit for an extended period of time with the sound distorting. Doing so may cause the connected speakers to heat, resulting in a fire.
• Do not stand or sit on, nor hang down from the unit as this may cause it to fall down or drop, resulting in personal injury and/or property damage.
• Have the unit checked periodically by the shop from where it was purchased. Failure to do so may result in corrosion or damage to the speaker or its mounting bracket that could cause the unit to fall, possibly causing personal injury.

WIRING

The speaker cable is not connected to the speaker unit when shipped from the factory. Follow one of the procedures below to connect the speaker cable to the speaker unit.

When No Bridge Connection is Required

• Step 1. Strip the speaker cable jacket as shown at right.

• Step 2. Detach the rear case. Remove the 4 screws holding the rear case.
  Note Gaskets are used to seal the unit’s rear case and screw holes. Since these must be used again when reattaching the rear case, take care not to lose or damage them.

• Step 3. Run the speaker cable through the cable gland.

• Step 4. Connect the speaker cable according to the polarity indication at the screw terminal.

• Step 5. Attach the rear case. Secure the rear case using the 4 supplied screws.
  In this case, take care not to pinch the wiring, and check that the waterproof gasket is secured into place.
  Note If wiring or the waterproof gasket is pinched between the rear case and the unit case, this causes water or moisture to get inside the rear case.

• Step 6. Securely tighten the cable gland.
  Note If loosely tightened, water or moisture may get inside the rear case.
