Up to five users are able to communicate with each other when using the U9911‐BSC. Up to four users are able to communicate with each other and also with a two‐way radio or other wired intercom system when using one of the U9900‐series gateways. Only one gateway/controller is required per system. Up to four belt stations can be connected to one controller/gateway. 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 Belt Station L L i i n n k k i i n n g g Before a belt station and a controller/gateway 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 units are within 1 to 3 ft (0.3 to 0.9m) of each other. 2. Ensure the U9910‐BSW is not already connected (see Status Indication). 3 of 11 19541P‐39 (02‐11) 3. Simultaneously (within 1‐2 sec) press and release the LINK/PTT button on the U9910‐ BSW and the controller or gateway to link with. 4. Amber LED’s will flash quickly on both devices. A momentary red LED indicates a successful close‐link. 5. Upon successful link the U9910‐BSW will attempt to establish a connection with the controller/gateway. 6. Upon successfully establishing connection the LED will flash green, a voice alert will be heard (see Table 1), and user sidetone will be enabled (see Communication). 7. Link and connection is now complete. Each belt station is able to be linked to only one gateway/controller at a time. A gateway/controller can have up to six belt stations linked and be connected to four of those six at one time. Tip: Once linked, the devices will not need to be linked again unless they are purged (see Purging). Units may be special ordered that do not have persistent links. 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 belt station. Table 1 below lists these states. Table 1: LED Status Indication LED Color Blink Rate Status Red Solid Initializing/power up Red Solid Close‐link successful 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 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) 4 of 11 19541P‐39 (02‐11) 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 U9910‐BSW belt station, press and hold the POWER button for approximately two seconds. The LED will turn red and then begin flashing orange. If the belt station has been linked to a controller or gateway and that controller or gateway is in range, the belt station will automatically connect within a few seconds. To power down the U9910‐BSW, press and hold the POWER button for approximately two seconds. The LED will turn red and then turn off. The belt station is now powered down. Auto Shut‐off Additionally, the belt station will automatically power down if it is disconnected from its gateway/controller for more than 30 minutes. Headset In order for the U9910‐BSW 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 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. 5 of 11 19541P‐39 (02‐11) Figure 3: Wearing the Headset VOX (Voice Activation) The U9910‐BSW 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 thresh…
