0 connections COnnECTInG THE OPTIOnAL WIrELESS rECEIVInG AMPLIFIEr To connect the rear speakers wirelessly, you have to purchase the wireless receiving module and TX card from your Samsung retailer. When you have Purchased the Wireless receiving Module (SWA-4000) Connect the front, center and Subwoofer speakers to the DVD Player, reffering to pages 19. With the DVD Player turned off, insert the TX card into the TX Card Connection(WIRELESS) on the back of the main unit. Hold the TX card so that the slanted side faces downward and insert the card into the port. The TX card enables communication between the main unit and the wireless receiver. Connect the left and right rear speakers to the wireless receiving module. Plug the power cord of the wireless receiving module in the wall outlet and switch the power switch On. 1. . ~ ~ . . Do not insert any other card except the TX card dedicated to the product. The product might be damaged or the card may not be removed easily. Do not insert the TX card upside down or in the reverse direction. Insert the TX card when the DVD Player is turned off. Inserting the card when it is turned on may cause a problem. If the TX Card is inserted, sound is not output from the Rear Speaker connectors on the main unit. ` ` ` ` ipod AUX IN 2 RESET Front Speaker (R) Rear Speaker (L) Subwoofer Center Speaker Front Speaker (L) Rear Speaker (R) WIRELESS RECEIVER MODULE RESET ipod AUX IN 2 Slanted side face left tX card This product is compatible with the wireless receiver module SWA-3000. M ` �� - Ht-Z310_XAA_1214.indd 202007-12-14 �� 6:06:37 1 EnG ● COnnECTIOnS resetting the Wireless receiving Module Reset the system if a communication failure occurs, or if the Link indicator (blue LED) on the wireless receiver does not light up and the "REAR CHECK" message blinks on the main unit's display. Reset the system while the main unit and the wireless receiver module (SWA-4000) is in Power Standby mode. With the main unit turned off, press and hold the remote control's REMAIN button for 5 seconds. The STANDBY LED on the front panel of the wireless receiver module blinks. With the wireless receiver module turned on, use a ball point pen or a pair of toothpick to press the rESET button on the back of the unit. The STANDBY LED on the front panel of the wireless receiver module blinks several times. Turn on the main unit. The LINK LED of the wireless receiver module is lit and the Reset is completed. If Power Standby mode continues, repeat Steps 1 to 3 above. 1. ~ . ~ . ~ ~ When the wireless receiving module setting is complete, no sound is output from the Rear Speaker Output Connectors on the back of the main unit. The wireless receiving antenna is built into the wireless receiver module. Keep the unit away from water and moisture. For optimal listening performance, make sure that the area around the wireless receiver module location is clear of any obstructions. Sound will be heard from the wireless rear speakers in DVD 5.1-CH or Dolby Pro Logic II mode only. In 2-CH mode, no sound will be heard from the wireless rear speakers. ` ` ` ` ` Place the wireless receiver module at the rear of the listening position. If the wireless receiver module is too close to the main unit, some sound interruption may be heard due to interference. If you use a device such as a microwave oven, wireless LAN Card, Bluetooth equipment, or any other device that uses the same frequency (5.8GHz) near the system, some sound interruption may be heard due to interference. The transmission distance of a radio wave is about 10m, but may vary depending on your operating environment. If a steel-concrete wall or metallic wall is between the main unit and the wireless receiver module, the system may not operate at all, because the radio wave cannot penetrate metal.
