will indicate the selection. For more information on selections, please see the Digital Intercom

Low Battery
Under typical conditions, the battery in the belt station will last up to 24 hours or longer. A voice
prompt will indicate to the user that the battery is running low. Additionally the Status LED will
turn red. At this point, approximately 1 hour of operation remains.
Purging
In some circumstances it may be desired to “purge” the U9110-BSW 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 uses a 3.7V 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).
