Function
The Energy Select or Power Control turns the
CodeMaster 100 power on and off. This control
also selects the energy level (Joules) for
delivering a shock.
The Charge button charges the defibrillator to
the energy level set on the Energy Select
control. Charge buttons are located on the
front panel of the CodeMaster 100 and on the
apex paddle.
The Sync button changes the operating mode
between immediate shock (asynchronous)
mode and synchronized with next R-wave shock
(Sync) mode. Note that the default is
asynchronous mode.
The orange Shock buttons, located on both
paddles, administer a shock when pressed
simultaneously.
