Start using the Multimedia Language Lab

How to use the HiClass II Control Panel

The keys at the bottom/left area of the panel (ie A1 to H9) correspond to the students' seating positions.

 This is the ID Key of a student. In this lab there are no students in the D1 — D9 column (this corresponds to the aisle) nor in the H1 — H9 column.

To the right of the panel, there are the Function Keys that allow you to select the actions you want to perform in class.

All the students’ desks have a student control box that controls the volume of the sound received via the Headphones.

The red button "Call" is used by students to speak to the teacher via headphones.


Common Function Keys

Student ID keys are used to select one or more students in conjunction with various functions.

This is student A1 ID Key

Each Student ID key has 2 LEDs.

. The GREEN LED indicates whether the student is on - or off-line, and will blink when the student has pressed their "Call Teacher" button.
. The YELLOW LED is On when the teacher has selected the student, and will blink when the student is assigned as the Master Student or Assistant, or is in Quick Transfer or Observe mode.

Quick Observe allows the teacher to monitor the screen/audio/mic of each student rotating from one student to another. Quick Observe combines Observe and Select All into one keystroke. The teacher can also determine the viewing interval of each screen (2-99 seconds).

  Press the Pause key to stop on any student screen; press Pause again to restart the rotating process.

Quick Transfer allows the teacher to transfer the Screen/Audio/Mic of a selected student to the entire class by pressing Quick Transfer and the student’s ID key. The teacher can switch from one student to another at any time by pressing the appropriate Student ID keys.

Quick Broadcast enables the teacher to broadcast his/her Screen/Audio/Mic to all students at the same time. This key combines Broadcast and Select All keys into one.

Use the BREAK key to end any previous function and return the panel to its initial mode.

The Black Screen key sends an automatic message to students’ monitor enabling the teacher to get their attention.

The Lock KB/Mouse key determines who has the control of the students’ keyboard and mouse.
When the LED is On, the teacher takes control of the student’s keyboard and mouse.
When the YELLOW LED is Off, the student can operate with the keyboard and mouse.

The Dialog key allows the teacher to speak to students through the microphone and headphones.
