I would suggest getting a operators manual on that particular model to figure out the lock code if that is actually it. Good luck

Please see below. I believe that you have set the tuning to LOCK, hence the KEY symbol. I have done the same thing with other radios. I bet you never forget this!

Manual Tuning with Rotary Dial You can select a higher or lower frequency by turning ROTARY TUNING. Set FAST/FINE/LOCK to select the rotary tuning increments or to lock the ROTARY TUNING dial. The following table shows the tuning increments for the FAST and FINE settings. '------'------'-------'------'-------' ' ' FM ' LW ' MW ' SW ' '------'------'-------'------'-------' ' FAST ' 0.1 ' 9 kHz ' 9/10 ' 0.005 ' ' ' MHz ' ' kHz ' MHz ' '------'------'-------'------'-------' ' FINE ' 0.05 ' 1 kHz ' 1 kHz' 0.001 ' ' ' MHz ' ' ' MHz ' '------'------'-------'------'-------' To lock the ROTARY TUNING dial, set FAST/FINE/LOCK to lock. This keeps you from changing the frequency if you accidentally touch the dial. NOTE: This locks only the ROTARY TUNING dial.

Testimonial: "I appreciate the advice - unfortunately the "Power" button does not function (even though it has fresh batteries installed). I could not try the rotary tuning fix!"

SOURCE: won't start key symbol flashing

The question here is how long did you leave the breaker off? Gaggenau ovens have a memory and I always advise turn the oven off for 5 mins before turning the breaker back on. Give that a try. The first thing the oven does when the power is reapplied is go thru a test phase which included locking and unlocking the door. The key symbol will go on and off during this. Sometimes you have to also can run a self clean then cancel it to reset the lock. This works as well.

Installing a echo board into a Realistic 5 pin mic.


95% of realistic mics are 5 pin It would be easier to install it inside the radio.Better than that you buy a noise toy that hooks to the rear of the radio and then your antenna hooks to the toy.

I have a # symbol in place of volume strength


Here is a link to the user guide: http://www.giantintl.com/RadioPDFs/Outdated%20Manuals/T6400_User_Manual_E.pdf

You might try reprogramming back to a very basic function by turning off any special features such as VOX, VibraCall, Interference Eliminator Code, Qt filtering, etc. Then see if the radio works any better. Also replace your battery pack with a known good battery, or trade batteries with a working radio.

Best regards.

Hi, I wonder how to use a TI89 to graph a multivariable functions's 3D picture. Thanks.


Hello,

First you must configure your calculator to perform 3D graphics
Press MODE
1.The first line shown is Graph. Unfold the hidden menu list with the right arrow and choose Graph 5:3D
2. Press ENTER to validate.

Now you must define the surface you want to draw
1. Press the [diamond] key then [Y=] to get a list of function names, the first of which is z1
2. Enter the following function (or your own) z1=(x^3*y-y^3*x)/390
( x cubed times y -y cubed times x) divided by 390.
3 Press ENTER.

Graph the function
Press the [diamond] key then [GRAPH]

The graphing screen displays progress in %. When it is finished you will see a weird sombrero.

Hope it helps

How do i get the channels to change on vx10 radio selector does not seem to change them radio recently repaired by yaesu and user manual not much help


The dial is probably locked. Look for a little padlock symbol on the display. Check the user manual for Dial or keyboard lock. Generally on Yaesu radios you use the function key plus a keyboard key. If the keyboard is labeled, you should see something that looks like a padlock next to the correct function key.

Galaxy DX 959


1. Remove bottom cover from radio. 2. On the main PCB, locate J33. (See diagram above) 3. Locate wires on pins marked "P5" (yellow) & "P6" (grey). 4. Cut wire on "P5" (yellow) and install a SPST switch in line. 5. Cut wire on "P6" (grey) and install a SPST switch in line. NOTE: By using two of the function switches available on the radio will eliminate the need for two new switches to be installed and mounted.
