• Never place hands close to the seat base when rotating the seat.

• Never place hands between the narrow spaces of the equipment or reach into the range of

motion limiters (eg. SC101, SC103, SC105, SC107 and SC108).

• Keep clear of the range of motion handles when the equipment is occupied.

• Be careful when operating the equipment to avoid tripping over equipment frames

(Stretching Tube of SC103 ).

• Do not sit on or lean against the armrests.

• If unusual situation has been observed (noises, no console display, loosen parts, and etc),

stop operation and contact local distributors immediately.

• Do not place the equipment outdoors or in area with high humidity.

4. Products are for continuous operation, and are not intended to be used in oxygen rich environment

nor to be sterilized. Do not perform servicing and maintenance while ME equipment is in

provides a path to reduce the risk of electrical shock.

2. Please unplug the power cord wire to shut down the power.

3. Improper connection of the grounding conductor can result in risks of electric shock. Do NOT modify
the plug provided with the equipment. If it does not fit the outlet, have a proper outlet installed by a
qualified electrician.

4. Pulling on the cord can cause damage to the power cord. You should always pull on the actual plug.

5. With energy conservation in mind, the console will automatically go dark when SMARC product has
not been used for 30 minutes. Main Page will reappear when the equipment is used again.

6. WARNING: To avoid the risk of electric shock, the equipment must only be connected to supply
mains with protective earth.

7. SMARC products forms a ME SYSTEM when connected to a power supply, and can be operated at a
voltage of 115V or 230 V.

8. Do not position the ME Equipment that makes it difficult to disconnect the device (eg. to unplug).

9. The USB socket on SMARC console should ONLY be connected with USB flash drive provided by
PMHC and authorized dealer. It should ONLY be used with the purpose of exercise data download
and prescription upload. SMARC products are not suitable for connecting with any other electrical
equipment. Connecting with other devices might cause potential electromagnetic interference.
