7-26 System 3
IZ2M/IZ2MH Stimulator
*The Blue LED is primarily used to indicate power on/off and safety ok/fault.
However, when the IZ2M/IZ2MH is actively stimulating (no faults) it also indicates
temperature deviation from optimal by blinking off (short off duration) with the
frequency of the off blink indicating the number of degrees off from optimal.
Power Status LEDs
Immediately to the left of the mains power button there is a row of small LEDs. The
first LED (from left) indicates whether the devices is being powered from mains or
battery power.
The four LEDs on the right end of the row indicate the power level of the battery.
The LED between the Power Mode LED and the Power Level LEDs is not used at
this time.
IZ2M/IZ2MH Features
Analog Outputs (Stim Outputs)
The analog output channels are arranged in sixteen-channel banks.
Stim Lights
The Stim Lights are located on the front plate of the IZ2M/IZMH and are labeled by
channel number. Each LED indicates the voltage at the corresponding electrode site.
The Stim Light will turn green when a channel has greater than +/- 150 mV at the
output and will turn red when a channel output is /- 10 V.
Fiber Optic Port (Fiber)
The fiber optic input port provides an isolated connection to the RZ base station.
One end of the fiber optic cable connects to the stimulator fiber optic input port
(labeled Fiber) and the other end connects to the fiber optic input port (labeled To
IZ2) on the back panel of the RZ base station. See “Hardware Set-up” on
page 7-23, connection diagram.
LED Color Status
Green the device is using mains power and the battery is charging.
Red the device is using battery power.
