You can delete any object from memory by pressing 2ND [VAR-LINK], use up/down-arrow to highlight the object, press F1, then select 1: Delete.

You can convert any result to numeric by pressing diamond ENTER. If you want all results to be numeric, press MODE F2, down-arrow to the "Exact/Approx" line, right-arrow, and select "APPROXIMATE."

What are the steps, when given two coordinates to work out the bearing and distance between them

Let us start by setting the terminology right: To locate a point on a plane you need two coordinates ( an X-value and a Y-value). If the point is in space, you need a third coordinate which may be called z, but let's us not complicate things unecessarily.

With just two coordinates, we will be able to locate at best one point.
Let us rephrase the problem: When given two sets of coordinates, how to calculate the distance between the two points.

Let (x1,y1) and (x2,y2) be the coordinates of two points in a plane. To calculate the distance between the points, one uses the formula
d (distance)= square root of ( (x2-x1)^2+(y2-y1)^2)
When you calculate the distance you must substitute actual coordinates for X1, Y1, X2 and Y2.

As regards the bearing, I am afraid that I am no expert in maritime nor in aircraft navigation and I will not venture stray out of my area of competence. However, I know that you need an axis that defines the direction with respect to which angles are measured.

If your reference axis is the horizontal axis on a cartesian plane you can determine the angle that the line joining the points makes with that horizontal axis by calculating its cosine, then extract the arcosine.
If (X2-X1) and (Y2-Y1) are both positive then cos(theta)=(X2-X1)/d, where d is the distance (positive value) calculated above.

I have no manual, how do I get the distance number to appear?

You can download a manual at

but simply, to get the distance to appear, turn on the unit with the large red ON/DIST button, aim the red laser dot at your desired target, and press the ON/DIST button again. The distance will appear on the display screen.

Toshiba A105 on off button (left top) loose.

I don't quite understand why I should get involved in this. If the product is within warranty, the owner will get re-imbursed. I am being asked if I have a solution for this problem, but the problem is not defined at all yet. When you have the problem defined, then I will gladly get involved but from what I see above, there is no problem at all. The only conclusion I can draw is that this is an advertisement of Toshiba, which I don't know where they buy their Mother Boards, of dubious quality, but I have had a dear friend in Argentina and he was quoted US $ 678.00 for a new MB. It just so happened that another friend of ours arrived in Buenos Aires and he had to repair the dc feed into the main point. I had a Compaq that their MB was so "good" that the wire inside the connector melted due to high heat and no one wanted to by pass it. This happened in Nicaragua and I fixed it the next time I vacacioned there. We have diffeent quality control for the USA and different for the other countries.... At least everything points to that!

I am using a EnGenius Senao 3220 plus bridge radio to pick up the signal from another same brand radio. i am able to connect to the network but i was not able to get in to the internet: "Unable to get...

If you have the radio configured as a bridge (not a bridge-router), you must ensure that your computer is in the same LAN IP subnet as the remote router. If the remote router supplies DHCP, this should happen automatically; if not, you must configure your computer manually.
Once there, you may have to manually define DNS servers on your computer in order to access machines on the internet by name. If you can browse to, but not to, your problem is solely lack of defined DNS servers. This is not an artifact of the Engenius units, but the remote server.
