Turning the E-Scope ON/OFF:
Press any button on the head of the E-Scope to turn it on. There is not an “OFF” button on the unit. To turn the E-Scope off, simply wait approximately 1.5 minutes and the unit will automatically turn OFF. When restarted, the E-Scope will return to the last volume automatically.
Adjusting the Volume:
There are 32 steps between the highest and lowest volume positions on the E-Scope II. The best way to adjust the volume is to press and hold the plus (+) or minus (-) buttons on the stethoscope head until the desired volume is achieved.
Switching between Heart and Breath Sounds.
To switch between Heart / Breath Sounds, press the "n" key on the head of the E-Scope. The default mode is Heart Sounds. By blowing on the stethoscope head as you press the "n", you can easily determine if you are in the heart or breath sound frequency mode. Breath sounds will sound higher.
Changing the Battery in your E-Scope
Simply snap the "open" panel on the back of your unit. Replace battery with a fresh "AAA." Replace battery evey 4 to 6 months. Remove battery for long periods of storage.
