1. Operating Modes
The Ruby Calculator will operate in one of three modes at any given time. The
default mode upon power up of the calculator is “Calculator Mode”. In this mode
the calculator will work as a normal scientific calculator with the limitations as
outlined in Section 10.
To form a chat session with another device the calculator will need to enter “Chat
Mode”. Prior to being able to enter chat mode, however, the calculator will need to
receive a password from the user. The default password is “123456”. Simply enter
this value into the calculator and hit the “Equals” button. (Note that this default
password may be changed; see Section 2)
Once this has been done the calculator may now enter “Chat Mode” by hitting the
“MODE/CLR” button. See Section 2 for a description of the functionality of buttons
in “Chat Mode”.
Once in Chat Mode the user may press the “SHIFT” button followed by the
“MODE/CLR” button to enter “Smash Mode”.
“Smash Mode” is a special mode for extra fast typing; see Section 3 for further
details.

2. Chat Mode Guide
Once in “Chat Mode” buttons take on different functionality. Descriptions of the
functionality for the above highlighted buttons are given below.
1. The “SHIFT” button provides secondary functionality.
2. The “ALPHA” button will cause the Ruby Calculator to attempt to connect to
another Ruby Calculator within range. If the Ruby Calculator is already
connected to a device this button will alert the user that the calculator is already
connected.

3. The “x
-1
” button is used to change the Chat Mode password. Press the “Equals”
button after typing in the nominated password.
4. The brackets buttons are used for scrolling through received messages. The
brackets buttons are also used for fast file navigation. Pressing the “)” button on
an opened file will skip 10 pages through the file. Pressing the “SHIFT” button
followed by the “)” button will skip to the end of the file. The other bracket button
does the same but skips towards the start of the file.
5. The “RCL” button is used for reading stored text files and adding new text files
from the RXO Chat App. After pressing the “RCL” button use the “Left” and
“Right” arrow keys to select a file. To write a new file to a slot hit the “Transfer
File” button on the RXO Chat App after selecting the desired file slot. To delete a
file from a slot press the “DEL” button after selecting the desired file. To read the
contents of a file hit the “Equals” button after selecting the desired file. You may
then use the left and right arrow keys to browse through the contents of the file.
6. The “Number Pad” becomes a pad for typing alphanumeric sentences in “Chat
Mode”. Refer to the diagram below for a visual aid of the functionality of the pad.
Type like the pad is from an old school mobile phone. Hitting a button once more
than the number of letters contained will print the number corresponding to that
button, eg hitting “abc” four times in succession will print the number “8”. If the
user wishes to type faster messages than this mode can offer they may enter
“Smash Mode” and turn the entire calculator into a keyboard. See Section 3.
7. The “MODE/CLR” button switches the calculator between “Calculator Mode”
and “Chat Mode”. Note that after establishing a connection the user may
alternate between the modes and will still receive messages when in “Calculator
Mode”.
If the user presses the “SHIFT” button followed by the “MODE/CLR” button while
in “Chat Mode” the calculator will enter “Smash Mode”. See section 3 for a
description of Smash Mode.

8. The “Pol(“ button will cause the Ruby Calculator to disconnect from any
connected devices. This button is necessary when the user wishes to switch the
calculator from one device to another.
This button contains secondary functionality. Press “SHIFT” followed by “Pol(“ to
toggle the state of the Bluetooth on the calculator between on and off. This may
be useful if the user only wishes to use the note storage feature and would like to
turn their Bluetooth off.
9.
The “^” button will open the “Special Symbol” palette. Although users are able to
type all standard alphanumeric characters and numbers using the Number Pad
they may like to type special symbols like letters from the Greek Alphabet or
Mathematical Symbols. This palette will allow the user to do so. See below for a
visual description of characters included in the Special Symbol palette.
10. The “sin(” button is the Auto-Scroll button for file reading. If the user wishes for a
file to automatically scroll page by page through a file without having to touch
the calculator they may push this button to enable or disable auto-scrolling. To
enable or disable Auto-Scrolling the user should push this button while reading a
file to toggle the state of the feature. The default auto-scroll time if 5 seconds per
page; this time interval may be modified by pressing the same “sin(“ button while
in standard Chat Mode – that is, not while the file reader is open.

11. The “tan(“ button is used for searching the internet. Type in a query while in Chat
Mode and then press this button to retrieve search engine results to the
calculator. Use the “M+” button to read the received search results.
The “tan(“ button is also used for the File Search feature. While reading a stored
file press the “tan(“ button. Next, type in your search query using the number
pad. Finally, press the “Equals” button to execute the search and you will
automatically skip through the file until the next occurrence of the query is found.
After executing a File Search you may want to then skip again to the next
occurrence of the query without re-typing the query again. To do so, simply press
the “SHIFT” button followed by the “tan(“ button to skip immediately to the next
occurrence from the previously entered search query.
12. The “M+” button allows the user to cycle through large received messages that
are larger than the size of the screen. See below for a visual description of what
pushing this button does to the screen.
13. The “,” button is the Emergency/Panic button. Pressing this button will force the
calculator out of “Chat Mode” and relock the device. The password will need to
be re-entered for all “Chat Mode” functionality to resume.
14. The “Equals” button in “Chat Mode” will send the typed message to the
connected device. If no device is connected this button will alert the user that no
devices are connected.
The “Equals” button also offers a feature in “Calculator Mode”. While in
Calculator Mode the “Equals” button will naturally evaluate the given expression.
What the user may then do, however, is press the “SHIFT” button followed by the
“Equals” button which will send the last evaluated expression and result to any
connected devices.
