Up to five users are able to communicate with each other when using the U9911‐BSC. Only one controller is required per system. Up to four belt stations can be connected to one controller. Model U9910-BSW Wireless Belt Station P/N 40992G-01 VOX Adjust Headset Connector Power Button Status LED Battery Compartment Battery Release Screw Link/PTT Button Figure 1: Overview of Controller 3 of 10 19541P‐44 (02‐11) L L i i n n k k i i n n g g Before a belt station and a controller can be connected, they must first be linked. As a security measure, the close‐link feature requires devices to be in proximity of about 1 to 3 ft (0.3 to 0.9m) in order to successfully link. This ensures that the units are not inadvertently linked with other units on the premises. Linking procedure: 1. Ensure power is on for both U9911‐BSC and belt station (see Power‐up/Power‐down). 2. Ensure units are within 1 to 3 ft (0.3 to 0.9m) of each other. 3. Simultaneously (within 1‐2 sec) press and release the PTT button on the U9911‐BSC and the belt station to link with. 4. Amber LED’s will flash on both devices. A momentary red LED indicates a successful close‐link. 5. Upon successful link the U9910‐BSC will attempt to establish a connection with the belt station. 6. Upon successfully establishing connection the LED on the controller will flash a green pattern corresponding to the number of belt stations connected. Tip: Once linked, the devices will not need to be linked again unless they are purged (see Purging). Each belt station is able to be linked to only one controller at a time. A controller can have up to six belt stations linked and be connected to four of those six at one time. S S t t a a t t u u s s I I n n d d i i c c a a t t i i o o n n s s The power button has a multi‐color LED in the center which serves as a status indication for the controller. Table 1 below lists these states. Table 1: LED Status Indications LED Color Blink Rate Status Red Solid Initializing/power up Red Once Connection Dropped Red Once Connection Established Red Any Low battery (approx. 1 hr remaining) Orange Slow Idle/Disconnected Orange Fast Link/Connection in Progress Orange Solid PTT asserted Green Slow Connected (pattern indicates number of belt stations connected) 4 of 10 19541P‐44 (02‐11) In addition to the LED, the belt station provides audio feedback for certain conditions as well. Table 2 below lists these conditions. Table 2: Voice Alerts Voice Alerts “Connection Established” “Connection Lost” “Low Battery” “Connection Deleted” (see Purging) O O p p e e r r a a t t i i o o n n Power‐up/power‐down To power up the U9911‐BSC controller belt station, press and hold the POWER button for approximately two seconds. The LED will turn red and then begin flashing orange. If there are linked belt stations within range, they will automatically connect to the controller in a few seconds after power up. To power down the U9910‐BSC, press and hold the POWER button for approximately two seconds. The LED will turn red and then turn off. The controller is now powered down. Headset In order for the U9911‐BSC to be used, a David Clark H9900‐series headset must be connected. To connect the headset, align the connectors as shown then push and turn clockwise (see Figure 2). There are separate left and right volume controls on the headset. Line up Orange Dots and Twist Figure 2: Headset Connection 5 of 10 19541P‐44 (02‐11) It is also important to properly wear the headset and correctly position the microphone. For optimum noise‐cancelling performance, position the microphone 1/8” to 1/4” (3‐6 mm) from your lips. Figure 3: Wearing the Headset VOX adjustment The U9911‐BSC has an innovative voice activation (VOX) system. VOX is intended to prevent background noise from being unintentionally picked up by the microphone while detecting and allowing voice communications. The VOX knob (see Figure 1) controls the threshold at which the mic becomes “hot”. When the mic is hot you will hear your own voice and other connected users will hear you as well. Pressing the PTT button will automatically make the microphone “hot” for as long as the PTT is held down, regardless of VOX setting. VOX Basics • VOX knob fully clockwise (CW): Mic is off • VOX knob fully counter‐clockwise (CCW): Mic is "hot" • VOX knob in‐between full CW and full CCW: VOX enabled VOX Adjustment Pro…
