Stimulus Setting/Output Display
This field of the LCD displays the stimulus setting/output level of the
unit in milliamps (mA).
If operating in the HIGH output range (NSL-5 lead set
attached)...
The unit powers on in the null mode and the display reads "- - -".
When a mode is selected, then the numeric value for the set
stimulus level is displayed:
• In integers when the current is between 1 and 80 mA
(e.g., 1, 2, 3, ... 40,... 53,... 78...)
• With two decimal places only when at 0.05 mA.
If operating in the LOW output range (RBW-5U lead set
attached)...
The numeric value for the stimulus display extends to:
• Two decimal places only when at 0.05 mA
• One decimal place when the value is greater than 0.05
(e.g., 0.1, 0.2, ... 0.9, 1.0, 1.1, 1.2, ... )
The stimulus output is set using the Stimulus Control knob
(Figure 2.1 - 2).
If the unit detects an open/disconnected lead condition or is unable
to deliver the displayed current setting for four (4) sequential pulses,
it will flash the output level display, and emit an audible indicator of
six (6) micro chirps every second.
The output level display is static when the unit is paused and when
stimulus pulses are being delivered. The audible chirp heard with
each stimulus pulse (or pattern), changes in duration, depending
upon the output range and the delivered stimulus output.

Stimulus Range Setting
This field of the LCD displays the maximum stimulus current setting
that can be achieved by turning the Stimulus Control knob.
When operating in the HIGH output range (as a Peripheral
Nerve Stimulator)...
• The NSL-5 interface cable is plugged into the Patient Lead
Output Connector (12) and
• The range is 0.05 mA to 80 mA
Output Current Level
All
≥ 1.0 mA
0.6 mA - 0.9 mA
0.4 mA - 0.5 mA
≤ 0.3 mA
When operating in the LOW output range (as a Peripheral
Nerve Locator)...
• The RBW-5U interface cable is plugged into the Patient Lead
Output Connector (12), and
• The range is 0.05 mA to 5.0 mA

Battery Life Indicator
.... .... .... .... .... Battery Life Remaining 80–100%
.... .... .... .... 60–80%
.... .... .... 40–60%
.... .... 20–40%
....0–20%
The LED segments of the Battery Life Indicator are solidly displayed
to the level of current battery life during use, until the battery life
drops below 20% (less than eight (8) hours of operation remaining).
When the battery life is reduced to a voltage that is indicative of
approximately eight (8) hours of operation remaining, the lowest
segment and the battery outline will flash at a rate of 1 Hz.
When the battery life is reduced to a voltage that is indicative of less
than four (4) hours of operation remaining, the lowest segment and
the battery outline will flash at a 2 Hz rate.
Caution: Operation will cease when battery voltage is
insufficient for the unit to function within specifications.
When the battery is too low to support proper operation, stimulus
will cease and error code Er3 will be displayed along with the
flashing outline of the battery symbol. When this occurs, shut off
the unit and replace the battery.
e
Stimulus Repetition Rate
This field of the LCD displays the rate (in Hz) at which the stimulus
pulses are delivered when in the Twitch or Tetanus modes. It is blank
when the unit is in the null mode, or operating in the DBS or TO4
modes.
f
Pulse Width
This field of the LCD displays the width (duration) of the stimulus
pulses. The pulse width default is determined by the stimulus output
range at the time of operation.
If operating in the...
HIGH output (Peripheral Nerve
Stimulator) range...
LOW output (Peripheral Nerve
Locator) range...
