over a user's belt.
Power Button

three seconds to turn it off. While a unit is powered on, a momentary Power Button press will display the
unit's status for three seconds.
Volume Buttons
Press the Volume Up or Volume Down button to increase or decrease the volume.
LK-1 or LKR-11 Display and Status

check unit Status. Press any button (i.e. Volume Up/Down) to activate the Display for that function.
Function buttons operate normally even when the Display is off.

charged in the Docking Station. To charge an individual unit, connect a USB charger to its Micro USB port. To
replace batteries on units equipped with the optional Alkaline Battery Compartment, depress the button on
the battery door to access the Battery Compartment. Insert three AAA size alkaline batteries.

the Leader depending on the Talkback Mode set by the Leader (see Page 26). The Participant Talk Button does
not function when the Leader chooses "Off" mode. Only one Participant can speak at a time. Soft Buttons are
disabled on Participant Transceivers.
Leader Buttons (LK-1 Only)
Press and release the Talk Button to toggle between Talk and Mute. It is not necessary to hold down the
Leader's Talk Button. The Leader configures ListenTALK Talkback Modes as described on Page 26. The Leader
also controls Group Pairing and passes the Group Name and Pair Key to Sub-leaders and Participants.
Sub-leader Buttons (LK-1 Only)
The Sub-leader's Talk Button operates like that on a Leader. A Sub-leader can Pair new Sub-leaders and
Participants making them members of a Group. In so doing, the Sub-leader passes on the Group Name and
Pair Key from the Leader.
