Safety Information
may test the Remote Control in different positions and observe which positions produce an
acceptable number of signal bars. Reduction of range may occur when in close proximity of
sources of electromagnetic disturbance such as:
• Television and computer monitors
• Short range RFID electronic tracking systems such as badge scanners and parking lot
scanners
Reduction of range may also occur within 18 feet of another Spectra WaveWriter System. Refer
to the tables in the "Electromagnetic Compatibility" section to determine the recommended
separation distances between the Spectra WaveWriter System and other transmitters.
The optimal orientation between the Stimulator and Remote Control is illustrated below. The
Remote Control may be rotated 360° as shown in the illustration and still maintain the same
communication range.

The Programming Wand communicates with the Stimulator through a RF telemetry link
from a distance of up to 45 inches (114.3 cm). Beyond this range, the Wand is more likely to
experience difficulty communicating commands to the Stimulator. Signal strength bars on the
Programming Wand indicate the strength of wireless communication between the Stimulator
and the Wand. The Stimulator Communication Indicator on the Wand flashes when data is
successfully transmitted between the stimulator and the Wand. If communication fails, the
Wand beeps up to three times. The Clinician Programmer displays an "Action unsuccessful"
message and instructs the user to move the Wand closer to the Stimulator and retry. Moving
the Wand closer to the Stimulator and or/changing the orientation of the Wand can improve
communication. Common sources of electromagnetic disturbance such as computers and their
power adapters can reduce the wireless range. To increase range, move the Wand six inches
or more from these devices. The optimal orientation for communication between the Stimulator
and the Wand is illustrated below.
