If the automatic new handset registration does not work by putting the handset in the base cradle, a manual registration process is available.
This is for the Accessory Handset model CL80113 for use with the following Base units: CL81113, CL81213, CL81313, CL82113, CL82213, CL82263, CL82313, CL82363, CL82413, CL82463, CL83113, CL83213, CL83263, CL83313, CL83363, CL83413, CL83463.
Press and hold the Handset Locater button in the base cradle until the In Use light is steady red. Release the button. The base display will say Registering…
Press the # key on an unregistered handset to start the registration process. That is it.
In OS X, clicking on a dock icon shows all open windows for the app. In Ubuntu, clicking on a launcher icon only shows the most recently used open window. This is annoying if you want to copy files between two folders or view all Xpad note windows.

Is it really that hard for a program to restore the windows that were open when you logged out? One of the things I liked about OS X was that it remembered the open file manager windows and folders. The default file manager on Ubuntu, Nautilus (Gnome Files), doesn’t do that. It just opens your Home folder. I wrote a couple of python scripts to remedy the situation.

I recently bought a new laptop from System 76 with Ubuntu preinstalled. This replaced a 7 year old MacBook Pro. Apple no longer sells 17″ laptops and HP and Dell linux laptops are well hidden on their websites. Read on for equivalent linux software to match what I used on OS X.

People are frequently asked to rate something on a scale of 1 to 10. Let’s take the pain Numeric Rating Scale (NRS-11) as an example. 1 means low pain (bump), 10 means extreme pain (migraine). Now what would warrant a 2 or a 9? A person simply can’t categorize pain into 10 different levels. The NRS-11 groups the 10 pain levels into 3 categories (Mild, Moderate, Severe). Why not just use a 3-point scale or the category names?
I postulate that most 10-point scales can be replaced with 5-point scales with no loss of information. For analysis purposes, most responses are going to be grouped into 3 – 5 categories or averaged.
Conversion of existing 10-point data values to 5-point data values is easy.
- Add 1 to the 10-point value
- Divide the result by 2
- Drop the fractional part
Example for value 9:
- 9 + 1 = 10
- 10 / 2 = 5
Example for value 10:
- 10 + 1 = 11
- 11 / 2 = 5.5
- Drop the .5 = 5
