Question about Symbol MC 9090 (sym-mc9090gk0hbega2r) Wireless Portable Terminal

Open Question

The battery is sensitive. Anyone have this problem before?

Sometimes the gun does not power up. I do know that if you even gently press on the metal part on the sides (that releases the battery) it powers off. Would anyone know if this is related to the backup battery in the gun?

    I found that if I double click the battery icon in the system tray, it'll give statistics about the main battery and backup battery. I'm gonna assume it's the backup battery for now.

    This is an old problem, but I found that if I click on the battery icon in the system tray, there's two statistics: Backup Battery and Main. If the Backup Battery is "Very low" or "Critical," then it's time to replace it. Which is easy to replace, because it's like the trigger cord. In my case, it's behind the scan engine.

Metal detector 3110 ll stop detecting any small metals and is 15 days old, what can be the problem? Is like it lost 99% of the sensitivity in 2 weeks, with new Alkaline Batt,& I been very careful!

metal detectors are ******* batteries especially alkaline type so check the charge in the batteries with a voltmeter
if they are still at correct voltage , take it back for a warranty check or replacement

Bought a famous trails metal detector and when installing batteries and turning it on the needle shoots all the way to the left.Nothing will move it nor will it detect anything.the manual says something...

I have a metal detector similar to a Famous Trails.

This would indicate that your sensitivity switch is set to full high. Try rotating the sensitivity switch to the center. There should be a button just below the meter which, when pressed, causes the needle to center.

With sensitivity set to mid range and the needle centered, the buzzer should not be sounding unless the coil is near some sort of metal.

Make sure all of the other knobs, if any, are also centered.

Need a cmos battery

This mobo uses a CR2032 litium battery, easily found, and cheap. To chage it, you must unplug the power cord, wait for a minute, remove the old battery (looks like a coin), behind the second PCI white slot. To remove the battery use a pair of tweezers and gently press sideways a small metal trap latch that holds the battery in place. The battery will pop out. Put the new battery in place, first on the opposite side of the latch and gently press down the battery in place till you hear a clic. Be careful with the battery's position. Positive side up, where are the trademark and model of the battery. Then, plug back the power cord. It will be necessary to reconfigure the BIOS settings.

I have the Nerf Stampede ECS and I have brand new batteries in, the jam door is closed all the way, the clip is inserted and the on/off is switched to on. It is like the gun is getting no power.

1.) Check to see if the batteries are inserted right.
2.) If for some reason they aren't pressed up against the metal right, add metal between the batteries and the conductors to insure they are in full contact.
3.) Did you screw in the battery pack all the way? I'd check that.
4.) (The hard) look inside the gun (unscrew the plates) and find out if the circuit is 'complete'. One of the factors in the gun's circuit being complete (jam door, batteries, or clip) may not be working the proper way.

Good luck with your problem.

Also- are you sure they are brand new?

Try getting a full refund if you can, if all else fails.

Take a few pictures of the internals and email them to me at I'll try to see if I can come up with a probable answer.

Turns on for a few seconds, lens starts to extend, turns off.

Assuming that the battery is OK, the most likely cause for this behaviour is an out-of-kilter lens drive. If you are lucky it's just some dirt or grit jamming the lens. Try blowing some compressed air in the lens grooves, or place the camera with unextended lens down and gently tap it to dislodge any dust or sand. Repeat while lens is extending. If this fails, GENTLY try to help the lens extend. Do not force (you risk permanent damage to the lens, assuming there is no damage now). If the lens rotates while extending, still gently try to help it to rotate, twisting in the direction of rotation.

Unfortunately, it's possible that the lens drive is actually damaged and can't be realigned manually. In this case the camera will need to be repaired. Also, even if you succeed in refitting the lens - you'll hear a slight "click" and the lens will start working happily - you'll need to exercise extra care in case the drive is no longer up to spec.

Unfortunately, "extending lens" cameras are very sensitive to accidents such as turning on while something is blocking the lens from extending fully. In most cases there's an overload sensor which will retract the lens and power off the camera - but sometimes the overload will have damaged the internal drive train, which is often (not very cleverly, in my opinion) made of plastic instead of metal.

Cannot load staples

At the back of the staple gun is a flat shaped metal piece. It's at the bottom. Push in, pull down, then pull the mechanism out. You'll see it's a metal rod with a spring, that is attached to that flat metal piece. The spring pushes against another flat metal piece, that has a hole in it, and travels back, and forth on the rod.

The flat metal piece that the spring pushes down the rod, pushes against the staples.

Remove this spring mechanism, slide the staples down the rails. The staples will be in the position of an upside down U. Replace the spring mechanism, and lock it back into place. (Push in, pull up)

Should, your question be in reference to the fact that you have staples loaded, but upon pressing the trigger nothing comes out:

In the front of the staple gun, is a flat metal piece that pushes down on the staples. One staple at a time. The flat metal piece is shoved down by spring pressure. The spring pressure is applied to the flat metal piece each time you squeeze the trigger. (Flat metal piece = Hammer)

Sometimes, Two staples try to come out. When they do, this flat metal hammer is stuck up in the gun. To free the flat metal hammer, remove the spring mechanism out of the back of the staple gun. (The spring mechanism discussed above) Remove any staples in the gun.
Try to use a flat blade screwdriver, and see if you can shove the flat metal hammer in the front of the gun -> UP.
(DO NOT have the staple gun pointing at your face! DO NOT squeeze the trigger! DO NOT use excessive force)

If this method is of no avail for you, you have to disassemble the gun, and remove the metal hammer, and stuck staple/s.

Help! My finishing nailer seems to have stopped driving the nail, period. It sounds like it is working but I am not sure if the hammer is even pulling back into the driver enough to actually drive...

It sounds like your gun has jammed. The fix isn't hard. First, though,make sure that your compressor is putting up sufficient pressure. Most of my jams happen when I drive brads and forget to turn the compressor back on! If the pressure is good, you'll need to check for a jammed brad. Disconnect the gun from the compressor. Pull back the slide and remove the brads from the magazine. At the front of the nailer, you'll find a cover, close to where the brads exit the gun. Open the cap and it will reveal a tab that will give you access to the nailing slide. Your gun probably came with allen wrenches, and they may be located on the gun, or in the case. Mine are along the slide, tucked in, and look like a part of the gun. You'll need an allen wrench (most likely) to remove the two allen screws that hold the cover assembly to the gun. Remove the screws, making note how the piece comes off. With the piece off you should be able to see where the brads come to the nailer from the magazine. Look for a hung up brad here. If you note a silvery piece of metal in front of the magazine, fear not, that is the hammer slide. The compressed air powers the slide down, peeling a brad from the magazine and driving it in. If necessary, you can gently press the slide back up. Try not to bend it. Locate the jammed brad(s) and wiggle them out of the gun to clear it. Sometimes it is easier to push them back into the magazine and shake them out. It takes a little finessing to get it right, but perservere. Reassembly is the reverse of the break down. Oil your gun daily. I put a few drops of oil into the air inlet at the gun before I connect the air line, and then drive a few brads into scrap wood.
Hope this gets you going on your project.
Best regards, --WoobieDog--
