Should you have questions relating to your installation, it is advisable to contact either your dealer or the JBL Customer Service Department for advice. The performance of the subwoofer is directly related to its placement in the listening room and how you align the subwoofer with its satellite speakers. The ES150PW/ES250PW's wireless capability makes it even easier to properly locate the subwoofer in your room. Setting the volume of the subwoofer in relation to the left and right speakers is also of critical importance because it is essential that the subwoofer integrate smoothly with the entire system. Setting the subwoofer's volume level too high will result in an overpowering, boomy bass. Setting the volume level too low will negate the benefits of the subwoofer. Here are several additional facts on installation that may prove useful. Initially set the Subwoofer-Level Control ¶ to the "Min" position. Turn on your sub by pressing the Power Switch ¡ on the rear panel. Turn on your entire audio system and start a CD or movie soundtrack at a moderate level. Auto On/Standby Transmitter (Wireless Connection Only): The Status LED (not shown) will be lit in red when the unit is in Standby. When the transmitter receives an audio signal from the source, it will immediately turn on and the LED will turn to blinking green or solid green: RED = STANDBY (No signal detected, transmitter off) GREEN (BLINKING) = Transmitter is on but has not established a link with the wireless sub GREEN (SOLID) = Transmitter is on and has already established a link with the wireless sub The transmitter will automatically enter Standby mode after approximately 10 minutes when no signal is detected from your system. Subwoofer: With the Power Switch ¡ in the "On"position, the Status LED on the back panel will remain lit to indicate the On/Standby mode of the subwoofer. RED = STANDBY (No signal detected, amp off) GREEN = SUB ON (Wired signal detected, amp on) ORANGE = SUB ON (Wireless link with transmitter active) The subwoofer will automatically enter Standby mode after approximately 10 minutes when no signal is detected from your system. The subwoofer will then power on instantly when a signal is detected. During periods of normal use, the Power Switch ¡ can be left on. You may turn off the Power Switch ¡ for extended periods of nonoperation (e. g. , when you are away on vacation). Getting Started Confirm that the Status LED on the transmitter is on (red or green), the Status LED on the subwoofer is on (red, orange or green) and an RCA cable is connected from a source unit to either the LFE Input of the subwoofer £ or transmitter < or L and R inputs TM on the subwoofer. [. . . ] Like all wireless devices, the JBL wireless subwoofer's operating range may vary, depending upon variables such as building construction methods and materials, atmospheric conditions and other sources of interference. Please consult your JBL dealer or distributor, or visit www. jbl. com, for further information or assistance. Wall-Mounting the Transmitter Module NOTE: The customer is responsible for the correct selection and use of mounting hardware (available through hardware stores) that will ensure the proper and safe wall-mounting of the transmitter. Insert the two M3 x 4 machine screws through the wall bracket and into the rear of the transmitter module, as shown. [. . . ]
