2. Press-To-Talk Mode:
In Press-To-Talk Mode the Master Station speaker and the Slave speaker are
normally off. A push button is required at the Slave speaker to put the
speaker into transmit mode. The button must be held in for the duration of the
call.
Microphone Push-To-Page Switch:
When the Push-To-Page switch
(located on the EXP-TBA faceplate) is activated the Master Station speaker
will be turned on – with attenuation to reduce the possibility of acoustic
feedback, the Slave speaker will also be turned on. This condition will occur
even if the remote Master Station or Slave switches are activated, since the
Push-To-Page switch has priority.
Remote Master Station Switch – (optional):
This can be a foot operated or
a hand operated switch. It will activate the Master Station when it is pushed
and when the Push-To-Page switch is open. In this condition the Master
Station speaker is converted into a microphone. The Slave speaker is turned
on to broadcast the message sent from the Master Station.
The Slave Station Switch:
When the Slave station switch is pressed, the
Slave speaker is converted into a microphone. The Master Station speaker
will be turned on to receive the message from the Slave station. This condition
is valid as long as neither the Push-To-Page nor Master Station remote
switches are activated.
Button priorities are:
1. Faceplate Push-To-Page switch.
2. Master Station remote switch (either a hand operated button or a foot
switch).
3. Slave speaker switch.
Speaker Volume Controls:
The Master Station speaker Volume Control and The Slave Speaker Volume
Control knobs are located on the faceplate and can be adjusted to provide a
comfortable sound level.
The Master Station speaker Volume Control:
The Master Station speaker
Volume Control knob is used to adjust the volume on the Master Station
speaker. This should be done with input from the Slave speaker, since
activating the Push-To-Page switch will attenuate the Master Station speaker
volume.
The Slave Speaker Volume Control:
The Slave Speaker Volume Control
knob is used to adjust the volume on the Slave Speaker.
