3. Safety Precautions

Please observe the following precautions to ensure the safety of service engineers as well as operators

when using this system.

&ANGER: D o no use flammable gases such as anesthetics, or flammable liquids such t

, &ARNING: 1. Information concerning the terminal to which the potential equalization

conductor is to be connected (

To use another medical device in combination with this system, an equipotential wire for connecting to an equipotential bus must be supplied. For more information, contact your TOSHIBA representative.

* Be sure to connect the potential-equalization lead wire before inserting

the equipment power plug into the receptacle. Also, be sure to remove the equipment power plug from the receptacle before disconnecting the wire to avoid electrical shock.

2. Information concerning the functional earth terminal (6):

Use of the functional earth terminal as protective earth is not allowed in Europe. The system should be connected according to local requirements.

3. Do not connect this system to outlets with the same circuit breakers and fuses that control current to devices such as life-support systems. If this system malfunctions and generates an overcurrent, or when there is an

instantaneous current at power ON, the circuit breakers and fuses of the building’s supply circuit may be tripped.

4. Do not connect to the system transducers other than those specified by TOSHIBA, to prevent accidents such as fire.

ACAUTION:

5. Do not subject the transducers to knocks. Use of defective transducers may cause an electric shock.

1. Malfunctions due (1) Use of radio-wave-emitting devices in the proximity of this kind of

medical electronic system may interfere with its operation. Do not bring or use devices which generate radio waves, such as cellular telephones,

transceivers, and radio controlled toys, in the room where the system is

installed.

(2) If a user brings a device which generates radio waves near the system,

they must be instructed to immediately turn OFF the device. This is

necessary to ensure the proper operation of the system.

- CAUTION:

No. 2D730-148E*O

2. Be sure to install the system on a level floor and lock the casters. If this is not done, the system may move, injuring the service personnel.

3. Move the system forward or backward only. If the system is moved to the left or right, it may fall, causing injury. In addition, be sure to fix the moving sections such as the operating panel before moving the system. If such sections move, they may catch the hands or fingers of the persons moving

the system, possibly causing injury.

4. To prevent electric shock, do not connect the peripheral units (video printer, VCR, etc.) to an external outlet. Peripheral units should be connected to the service outlet of the system or the optional isolation transformer. For the connection procedures, contact your TOSHIBA representative.

5. The service outlet of the main unit is intended solely for recommended peripheral units. Do not connect devices other than recommended peripheral units to the service outlet. Connecting devices other than those recommended may cause the consumption current to exceed the power capacity of the main unit, possibly resulting in malfunction.

6. Do not place any objects on top of the monitor. They may fall, causing injury.

7. Do not allow fluids such as water to contact the system or peripheral devices. Electric shock may result.

8. Do not handle the system with wet or moist hands. Electric shock may result.

9. The monitor is a heavy unit. Two persons are required when mounting or removing the monitor. If a worker mounts or removes the monitor alone, he/she may be injured.

10. Be sure to turn OFF the power breaker and disconnect the mains plug from the outlet before removing the covers of the main unit and performing

internal wiring.

11. When discarding any part of this system, follow all applicable local

regulations.

12. Wear protective gloves to ensure safety and prevent infection when

performing unit replacement, board replacement, internal wiring, or cleaning.

13. Wait at least 30 seconds after turning OFF the power breaker and

disconnecting the mains plug from the outlet before replacing the battery. Otherwise, an electric shock may result.

CAUTION: I. When replacing the AC/DC tray of the SSA-770A, check the revision number of the

AC/DC tray supplied for replacement and follow the appropriate procedure according to the revision number.

1 .I When the new AC/DC tray is BSM31-2013E (no revision)

The AC/DC tray is not compatible and must not be used to replace the existing tray.

s-3

CAUTION: 1.2 If AC/DC tray BSM31-2013E-G or BSM31-2013E-I is supplied

(1) Wind the cables around the core as described below.

(a) Wind the FAN/RELAY signal cables (two lines) between the AC/DC tray and

transformer tray ONE time around the core (TWO turns). * When the cable is passed through the core the first time it is counted as

one turn. Therefore, winding of the cable one time corresponds to TWO turns.

(b) Wind the LED signal cable (which is connected to the top of the AC/DC tray)

between the AC/DC tray and the transformer tray ONE time around the core

(TWO turns). * When the cable is passed through the core the first time it is counted as

one turn. Therefore, winding of the cable one time corresponds to TWO turns.

(2) The metal sheet for EMC compliance should not be installed.

CAUTION: 1.3 When the new AC/DC tray is BSM31-2013E-H or -J or later (revision or later)

(1) Wind the cables around the core as described below. Note the number of times

each cable is to be wound around the core. (a) Wind the FAN/RELAY signal cables (two lines) between the AC/DC tray and

transformer tray FOUR times around the core (FIVE turns). * When the cable is passed through the core the first time it is counted as

one turn. Therefore, winding of the cable four times corresponds to five turns.

(b) Wind the LED signal cable (which is connected to the top of the AC/DC tray)

between the AC/DC tray and the transformer tray ONE time around the core

(TWO turns). * When the cable is passed through the core the first time it is counted as

one turn. Therefore, winding of the cable one time corresponds to TWO turns.

(2) The metal sheet for EMC compliance should be installed.

Press the metal sheet firmly against the rack so that the upper tab is flat and then

secure the sheet using screws1 and 2.

(2) Press the metal sheet for EMC compliance firmly

against the rack so that this tab is flat and then secure the sheet using screws 1 and 2.

CAUTION: 2. Voltage setting for replacing the transformer tray and TRANS-unit

The switches used to select the output voltage according to the input voltage are installed on the transformer tray and the TRANS-unit.

When the switches of the replacement units (transformer tray and TRANS-unit) are not

set correctly, the power supply may not start up correctly, or a malfunction of the connection equipment may result. Be sure to check the settings.

For the transformer tray
