What causes continual beeping


With some smoke detectors, this indicates a low battery. Try putting in a new battery and see whether it stops beeping. If it doesn't add a comment to this question and specify the make and model of your smoke detector.

How do I change the battery in my Model sco5 canazur@yahoo.fr


It appears to have the tab on the lower left (7 o'clock) position. The tab should release with slight pressure and allow the battery door to open. Replace battery and close door. Good luck.

I have a oreton scientific portable public alert radio model wr108 I need a battery for it where can iorder one there aren't any in my area



  • That being said, your radio can use 3 regular AA batteries. If it were me I wouldn't fool with tracking down some overpriced battery pack because all that battery pack is, is 3 AA batteries in some shrink tube. Buy 3 AA rechargeable batteries from Radio Shack or Wal-Mart.

  • Also you need to hit the reset button in the back when ever you change the batteries.

How to change incoming message alert on samsung sgh d600


Hi I'm afraid that on earlier Samsung models it was not possible to change the alert tone for sms messaging. You usually only got 10 preset alerts. Ringtones was ok to change only if in right format recognised by handset.
Hope that helps?

Need to make sure programmed


Program the Midland 74-109 Weather Radio
a) Turn unit on. Extend the antenna. Adjust volume up slowly; Do you hear anything? If not, try replacing the 9 volt battery with a fresh one, in the accessible battery compartment underneath the unit. Repeat above steps.
b) If no sound is heard, turn unit over and look for "WEATHER" slide switch on bottom. With unit on & volume adjusted to comfortable hearing level, slowly slide switch down (or up) through various frequencies [1)162.550, 2) 162.400, 3) 162.475, 4) 162.425, 5) 162.450, 6) 162.500, 7) 162.525] until voice transmissions are heard. This should be the closest National Weather Service (NWS) broadcast for your area. Check the NWS website at http://www.nws.noaa.gov/nwr/nwrbro.htm for your state, click on the state name, and look for the site name or site location nearest you. The frequency for that site should be the strongest, and appropriate for your area.
c) You can set the alert tone, for special weather alert broadcasts, on the bottom of the unit on the slide switch marked "ALERT". Set the switch to the desired type of alert: 1) LED [LED on top of unit (marked ALERT) lights up when alert is broadcast-no siren tone/alarm is heard] 2) LED & ALARM [LED lights up and alarm/ siren tone is heard] 3) VOICE [LED on top of unit lights up and voice broadcast is heard, only; no siren tone/alarm is heard].
d) Be sure to press the "ALERT" button on top of the unit and leave the volume at a comfortable listening level to hear weather alerts for your area (Alert LED on top of unit lights up to show Alert function is active). You can test the present volume level by pressing the "TEST" button. Be sure to press the "ALERT" button again after listening to the volume level to re-set the Alert function. You can listen to weather broadcasts anytime, by pressing the "WEATHER" button. After listening, be sure to re-press the "ALERT" button to reset the Alert function.
e) 9 volt battery life should last about 6 to 7 months, depending on how much unit is used an number of alerts received. Replace battery every 6 months, or when you replace your smoke alarm battery, or at beginning and end of daylight savings time. A 12 volt AC adapter to replace the battery, can be used. One should have been supplied with unit. If not, a replacement can be found at Radio Shack.
f) This should complete your Midland Weather Alert Radio Model 74-109 programming.

Can't turn off ALERT - battery low


taking the battery out should do it. Or maybe just turning it off. To take out the battery, just take the back cover off and pull the battery off.
