Change battery in OxyWatch oximeter

First off, figure out what model of oximeter you have. There seem to be about 6 different ones.

Email the manufacturer at;

Ask them for a service manual for the model that you have. And also for explicit instructions on how to change the batter, and what type of replacement battery it uses.

How do I open battery compartment & install batteries in ChoiceMMed Oxywatch CF309 which is a Pulse Oxymeter

I have the same model. Flip unit ove so you can see bottom. Hold your thumb on the side with the arrows (but don't wrap your thumb around too much. Just enough to hold that side.) Hold the other side with your index finger. Squeeze thumb and finger together while pulling back towards you on Thumb side. Hope that helps.

How do I get the pedometer to work on this unit?

Hold the pwr button for over 2 secs. to change modes. Tap to stop on first rt. arrow. (R resets to zero)--otherwise, tap to start and note blue arrow under "reset arrow). Start walking. Often it appears not to work but be patient. It will add all steps and/or jerks. When display goes blank, hit pwr. button momentarily for total "steps." It may be two steps off your count at times, but that matters not..

I just purchased the ChoiceMMed pulse oximeter with pedometer. I cannot figure out how to get the pedometer part of it to work. There is nothing about it in the quick operation guide that came with it....

Perhaps you could ask the person / firm who sold the oximeter, or you could try reading the manual? Far easier than trying someone else to find and read the manual and type here, what you have in print already?

How do i get out of pedometer mode?

The unit powers on in the last mode it was in when it was powered off (Oxygen Tester or Pedometer). If it is in pedometer mode, do this: Hit power button once to start. If in pedometer mode, simply keep pressing the power button and watch the tiny curser jump between the four symbols. When it lands on the "Return Arrow" hold down the power button for a few seconds until the unit returns to the Oxygen Tester mode. ~jim
