Battery Replacement - Welch Allyn PneumoCheck Operating Instructions Manual

BATTERY REPLACEMENT

The PneumoCheck batteries are intended for many charge/recharge
cycles and are warranted for two years (expiration date is imprinted
on each battery). For maximum battery life, always replace both
batteries at the same time.
To replace:
1.
Turn the PneumoCheck OFF.
2.
Using a coin, loosen the two set screws on the bottom of the
PneumoCheck (these screws will loosen, but cannot
be removed).
3. Remove the pneumotach assembly from the top of the
PneumoCheck.
4.
To remove the batteries, turn the PneumoCheck upside down
and tap lightly.
