4.1 OPERATOR AND LOCK CONTROLS
4.1.1 POWER SWITCH – This switch controls power to the unit.
4.1.2 SPEAKER SWITCH – This switch allows the tender to turn off the speaker. If the
tender is using a headset, it may be necessary to turn off the speaker in order to
prevent acoustic feedback.
4.1.3 PUSH-TO-TALK BUTTON – This switch allows the operator to talk to the chamber
occupants when operating in the 2-Wire mode. It is not necessary to use this
control in the Full Duplex (4-Wire) mode. When using Full Duplex mode, this
control allows the operator to interrupt the audio entertainment by muting when the
switch is pressed.
