General Precautions for Handling This Product
1. Circumstances not covered by product guarantee
• If the product was disassembled, altered, or repaired by the customer
• If it was dropped, broken, or given another strong shock
• Use at overvoltage, use outside guaranteed temperature range, storing outside guaranteed temperature range
• If power was turned on while connection to the AC adapter, USB interface cable, or target system was in an
unsatisfactory state
• If the cable of the AC adapter, the USB interface cable, the emulation probe, or the like was bent or pulled excessively
• If an AC adapter other than the supplied product was used
• If the product got wet
• If this product is connected to the target system when there is a potential difference between the GND of this product
and GND of the target system.
• If the connectors or cables are plugged/unplugged while this product is in the power-on state.
• If excessive load is applied to the connectors or sockets (As for handling, please see 2.3 Mounting and Connecting
Connectors (When Using S Type) or 2.4 Mounting and Connecting Connectors (When Using T Type).
• If a metal part of the power switch, cooling fan, or another such part comes in contact with an electrostatic charge.
• If the product is used or stored in an environment where an electrostatic or electrical noise is likely to occur.
2. Safety precautions
• If used for a long time, the product may become hot (50°C to 60°C). Be careful of low temperature burns and other
dangers due to the product becoming hot.
• Be careful of electrical shock. There is a danger of electrical shock if the product is used as described above in 1.
Circumstances not covered by product guarantee.
