608 Instruction
M E D I CAL- D E NTAL A PP L I CATI O N S
D o not use the amplifier INPUTs for direct patient connection. Signal currents a t these connectors, as well as
leakage currents, may exceed values considered non-hazardous for direct patient connection.
Although this instrument is not to be used for direct patient connection, interconnecting this Monitor with other
equipment can result in application of excess current to the patient. It is extremely important that the equipment
be interconnected in accordance with NFPA
768-
T, Tentative Standard for the Safe Use of
in Patient
Care Areas of Health Care Facilities, section 3038, "Signal Transmission Between Appliances".
Do not operate this instrument in the presence of flammable gases or anesthetics. Explosion can result from
operation in such an environment.
US E TH E P R O P E R F U S E
Refer fuse replacement t o qualified service personnel only. T o avoid electric shock and fire hazard, use only the
fuse specified in the parts list for your instrument and which is identical in the following respects:
A. Type-Slow blow, fast blow, etc.
B. Voltage rating-250 V, etc.
C. Current rating.
DO N OT R E M OV E INSTR U M ENT COVE R S
High-voltage is present inside the instrument. To avoid electric shock, operating personnel must not remove
protective instrument covers. Component replacement and internal adjustments must be made by qualified service
personnel only.
LI M IT I N PUT S I GNA L V O LTA G E
T o avoid electric-shock hazard, do not apply input signals o f more than 2 5 volts (dc
+
peak ac). Should fault
conditions occur however, the instrument is protected for application of input signals up to 100 volts (de
+
peak ac).
EX E RC I S E CA R E WITH INTENSITY LEVEL
Exercise care in establishing the correct display intensity; a high-amplitude Z-Axis input signal, combined with an
excessively high setting of the INTENSITY control, may damage the crt phosphor. Therefore, set the INTENSITY
control for just enough display intensity for good visibility.

WARNING
This equipment generates, uses, and can radiate radio frequency energy and may cause
interference to radio communications if not installed and used in accordance with the
instruction manual. It has been tested and found to comply with the limits for Class
B
com
puting devices pursuant to Subpart
J
of Part
15
of FCC Rules, which are designed to provide
reasonable protection against such interference when this equipment is operated in a com
mercial environment. Operation in a residential area is likely to cause interference in which
case the users at their own expense must take whatever measures may be required to cor
rect the interference.
