D.6.0 How to drive a Psion based SMART Communicator
Familiarity with the Psion
The Psion is supplied with several manuals to described its function. The main keyboard functions that are important are the yellow keys. Press “ON” and see the functions of the arrows to move the cursor around the selections in the menu. Press “EXE” to see the Psion functions. Note that a short cut to selecting a menu item is to press the key with the initial letter of the required selection – for example “O” switches the unit “OFF”.
Note that if the “CALC” option is selected, the keyboard changes from the “Alphabet” marked on the keys, to the “numbers” and symbols marked above the keys. The Psion selects the expected function required of the keyboard. This function can be changed back by depressing the “SHIFT” key.
MOBREY Menu
If “MOBREY” is selected from the start up menu on the Psion, by pressing “EXE” the space available in the A memory of the Psion is checked. If there is insufficient then a message is displayed and the program returns to the main menu. Data, Note Pad or Diary files in A must be removed to allow the program to run. The SMART Communicator then establishes whether the SMART interface unit is plugged in or not.
