Overview

The U9110-BSW(EU) (40992G-20) Digital Wireless Belt Station is a portable wireless communication device that when used in conjunction with a U9120-W4(EU) (44002G-02) Digital Wireless Gateway becomes part of a wireless intercom system. Up to four belt stations can be connected to one gateway.

Figure 1: Overview of Belt Station

The U9110-BSW(EU) Digital Wireless Belt Station employs an adaptive SMART-VOX system which does not require adjustment by the user. The system automatically monitors background noise levels and detects voice.

Linking

Before a belt station and a 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 U9110-BSW(EU) is not already connected (see Status Indication).
3. Simultaneously (within 1-2 sec) press and release the PTT button on the U9110-BSW(EU) and the gateway 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 U9110-BSW(EU) will attempt to establish a connection with the gateway.
6. Upon successfully establishing connection the LED will flash green, a voice alert will be heard (see Table 1), and user side-tone will be enabled (see Communication).
7. Link and connection are now complete.

Each belt station is able to be linked to only one gateway at a time. A gateway can have up to four belt stations linked/connected at one time.

Tip: Once linked, the devices will not need to be linked again unless they are purged (see Purging).

Status Indications

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.

Operation

Power-up/power-down

To power up the U9110-BSW(EU) 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 gateway and that gateway is in range, the belt station will automatically connect within a few seconds.

To power down the U9110-BSW(EU), 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 for more than 30 minutes.

Headset

In order for the U9110-BSW(EU) to be used, a David Clark H9100-series headset must be connected. To connect the headset, align red keyways and push. Pull back gently on the connector (behind the quick-release collar) to ensure it is properly locked. To disconnect, pull back on the quick-release collar.

There are separate left and right volume controls on the headset.

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 2: Positioning the Microphone

Communication

The user will hear his own voice (side-tone) only when the belt station is linked to a gateway, assuming the microphone programming for intercom on the chosen selection is either hot-mic or VOX; if the selection for mic function for intercom was programmed for PTT, the user will hear side-tone when the PTT is depressed . Side-tone provides feedback for the user to know he is connected. In general, if you can hear your own voice, the other users can hear you as well.

Range

The unimpeded line-of-sight range of a belt station and a gateway should be at least 500 ft (150m). If you are in an environment with metal or concrete walls, this range could be reduced. If the belt station enters into a “fringe” reception area, a brief sequence of three beeps will be heard in the headset. This is to serve as a warning of a possible disconnection if conditions are not improved. When possible, the user should attempt to regain line-of-sight contact with the gateway. When the belt station travels out of range of the gateway, a voice prompt will indicate that the connection has been lost. To reconnect, simply move back into range and connection with the gateway will automatically be reestablished, also noted by a voice prompt.

PTT

The PTT button allows the user to activate the headset’s microphone momentarily while depressed. The actual microphone transmit function (e.g., radio transmit or  intercom) willdepend on the specific programming for the chosen selection on the belt station. For more information see the Operation Digital Intercom manual (19549P-31). (see section on User Interface to review programming options).

Selections

The U9110-BSW(EU) has the capability of switching between four “selections”. These selections are defined within the Digital Intercom System graphical user interface and can be configured to provide different communications paths between users and radios, as well as the behavior of auxiliary audio devices connected to the system.

To cycle though the four selections, briefly press and release the power button. A voice prompt will indicate the selection. For more information on selections, please see the Digital Intercom manual (19549P-31).

Low Battery

Under normal conditions, a belt station’s battery can be expected to last for approximately 24 hours of continual use (Note: if a Hear-through headset model is in use, this nominal use time could be reduced by as much as 50%, depending on noise conditions and amplification level). A voice prompt will indicate to the user that the battery is running low. Additionally, the Status LED will turn red, at which point approximately 1 hour of operation would remain.

Purging

In some circumstances it may be desired to “purge” the U9110-BSW(EU) of its known gateway. Typically purging is not necessary unless there are multiple gateways in the same vicinity and you wish to link a belt station to a different gateway. A belt station can be linked to only one gateway at a time.

Purge Procedure

1. Power down belt station (see Power-up/Power-down).
2. Press and hold PTT button. Do not release.
3. Power up the belt station (see Power-up/Power-down).
4. Release POWER button when red LED turns off.
5. Release PTT button.
6. A voice prompt will indicate that the connection has been deleted.

When this procedure is complete, the belt station will not automatically connect to a gateway and must be linked again.

Battery Removal & Charging

The U9110-BSW(EU) uses a 3b.7V Li-Polymer rechargeable battery. This battery is removed by loosening the battery release screw (See Figure 1). These batteries are charged with the A99- 14CRG 4-bay battery charger (41034G-02).

When installing a battery, take care to align the battery properly and fully tighten the screw (see Figure 3).
