2.7 Operation & Usage

1. Turn on the OCU, check the android OS booting by the LCD display. After boot-up, the

operator can use the OCU.

2. There are six (6) keys on front of OCU. The function for each key is as below;

- ROUTE: The selection of in-service route.

- START: The operator pushes this button when start the service.

- Payzone 1: The selection of fare payment type

- Payzone 2 : The selection of fare payment type

- Payzone 3 : The selection of fare payment type

- CANCEL: Cancelation of event.

3. The LCD display has a resistive touch panel for operator to operate the OCU by using his

finger.

4. There are USB port, Audio port and External Micro SD card slot on the right side of OCU.

5. There are Digital In/Output port, Serial communication port and LAN (Ethernet) port on the

rear cover of OCU. So, it supports variable interface.

6. The OCU has audio interface to support the announcement for operator.
