2. Operation – User Interface
2.1. MCU-002 Keys and Functions – Basic Operation
The MCU-002 consists of 10 hardware keys to control the TZT9/14/BB and TZTL12F/15F/2BB as described below.
Sets the NAVpilot-300/711C to STBY or AUTO modes
Sets the ship in the center of the screen
Switches the joystick functions between Cursor and Scroll
Moves a cursor in 8 directions
Acts as rotating RotoKey™ clockwise
Acts as rotating RotoKey™ counterclockwise
Short presss to cancel
Long press to enter an MOB point
Short press to access the Home page
Long press to open the Brilliance control box
2.2. MCU-004 Keys and Functions – Basic Operation
The MCU-004 consists of 10 hardware keys to control the TZT9/14/BB and TZTL12F/15F/2BB as described below.
Sets the NAVpilot-300/711C to STBY or AUTO modes
Short press to access the Home page
Long press to open the Brilliance control box
Switches an active display
Switches the joystick functions between Cursor and Scroll
Sets the ship in the center of the screen
Acts as rotating RotoKey™
Moves a cursor in 8 directions
TZT9/14/BB: Same as pushing RotoKey™ key
TZTL12F/15F/2BB: Activates Edge Swipe functions
Short presss to cancel
Long press to enter an MOB point

2.3. MCU-004 Keys and Functions – Differences from MCU-002
The MCU-004 keys work almost the same as the MCU-002 except for the following unique keys and features.
Uniqueness with MCU-004 – Overview
The [Switch Disp.] key switches an active display when there are
multiple MFDs in the network.
A big rotary knob offers a friendly operation similar to the RotoKey™
of TZT9/14/BB.
The [Edge] key works differently between TZT9/14/BB and
TZTL12F/15F.
TZT9/14/BB
It works the same as the [ENT] key of MCU-002
such as showing RotoKey™ menus and selecting the RotoKey™ or contextual menus.
TZTL12F/15F
It activates the Edge Swipe functions. Instead of swiping the screen from the top, bottom, right, or left edge,
press the [Edge] key and move the joystick in the same direction as you edge-swipe with your finger.
[Edge] + Joystick [Up] : Layer
[Edge] + Joystick [Down] : Quick Access page
[Edge] + Joystick [Right] : Data Box
[Edge] + Joystick [Left] : Universal setting options
(1) Buzzer
A buzzer is built in. When an alarm is generated on the display, the sound will be heard at the MCU-004.
(2) Switch Disp.
The [Switch Disp.] key switches an active display when there are multiple MFDs in the network.
In the example at right, there are two (2) displays.
The MCU-004 is connected to Display No. 1. By
default, the MCU-004 controls Display No. 1. Pressing
the [Switch Disp.] key, the MCU-004 now controls
Display No. 2. Section 4 describes how to group
controllable displays in the network.

(3) Large Rotary Knob & Joystick
The large rotary knob offers a friendly operation for zoom in/out similar to the RotoKey™ of
TZT9/14/BB. The big joystick makes it easier to move the cursor. With TZTL12F/15F v3.01 and
higher, pushing the joystick selects the highlighted items in contextual menus, settings, Layer, etc.
(4) Edge Key
The [Edge] key works differently between TZT9/14/BB and TZTL12F/15F.
TZT9/14/BB
It works the same as the [ENT] key of MCU-002 such as showing RotoKey™ menus and selecting the
RotoKey™ or contextual menus.
TZTL12F/15F
(1) It activates the Edge Swipe functions. Instead of swiping the screen from the top, bottom,
right, or left edge, press the [Edge] key and move the joystick in the same direction as you
Edge Swipe with your finger.
[Edge] + Joystick [Up] : Layer
[Edge] + Joystick [Down] : Quick Access page
[Edge] + Joystick [Right] : Data Box
[Edge] + Joystick [Left] : Universal setting options
(2) The [Edge] key also works to select the highlighted items in contextual menus, etc. like pushing the joystick.
Tip – TZTL12F/15F v3.01 or later with MCU-002 for Edge Swipe
With the MCU-002 connected to the TZTL12F/15F v3.01, the MCU-002 [ENT] key works
the same as the MCU-004 [Edge] key. Edge Swipe functions are accessible by pressing the
MCU-002 [ENT] key and moving the joystick.
