4.5 MAIN AND EXTENDED MENUS
The Main Menu gives access to the H201T i ’s most frequently used parameters and
commands. The Extended Menu gives access to all parameters and commands (including
all parameters and commands from the Main Menu).
Note: Even if the H201Ti’s menu system gives access to all its operation parameters, using
a host computer and General Electric Canada’s Hydran Host software simplifies the tasks.
For more information, see the Hydran Host Software Manual.
Table 4-5 on page 4-10 summarizes the functions of each submenu of the H201T i ’s
embedded software.
