1. Product Configuration
1.1 Maintenance Mode Password
BioCon-500 has two system modes. One is Normal mode, and the other is
Maintenance mode. Normal mode is for the normal user, and Maintenance mode is for
the technicians in the hospital or service engineers. To enter the maintenance mode,
push LEFT key with ENTER key being pushed and then push PRINT key after the
system is turned on and the top screen is displayed in normal mode. When you press
‘ENTER+LEFT+PRINT’keys, the BioCon-500 asks for the Maintenance mode
password (after the firmware version 3.1.009). Input ‘1122’for the password. You
cannot change the password.

at the system.
Console Controls system operation and various signals, and handles
signal transmission and reception.
Ultrasonic Probe Transmits and receives the ultra
sonic signals, being used in close
contact with the patient.
The Console consists of a printer module, aLCD module, a battery module, and a
number of boards. Its functions are as below.
Component Function
ChargeBoard Charges the battery module with DC 16V input from a DC
adapter.
Battery Board Connects the ChargeBoard and the Battery Module.
Analog Board
