I have several 3Kos machines we unfortunatly bought that I cannot make the volume go up. All 4 machines have low volume alarms that will not turn louder when maxed out. They all alarm, but compared to the newer K machines the alarm is faint and wont get louder...any suggestions?

We have had this problem in the past. Each time I replaced the alarm speaker. Afterwards, the staff started complaining that the alarms were too loud.

I had this happen last week on a 3Kos machine. I repalced the 100 ohm potienometer. Now I can adjust the volume as needed.

Have repaced 10 or so speakers in 3kos machines in the last year. Must of been a bad run of speakers.

Same here 3kos, most of mine had to replace the speaker

have seen nurses and techs with oversoaked bleach rags cause this

Thanks everyone!!! I replaced the speakers and as earlier suggested the nurses say they are now too loud! I Appreaciate the input.

thanks it was speakers
