Product Handling Information

Operational precautions (instrument)

Only use the product including accessories for their intended purpose.

Do not drop or physically impact the instrument.

The instrument is made of solvent-resistant materials but that does not mean it is resistant

to all chemicals. Do not expose the instrument in strong acid or alkali solution, or wipe with

such solution.

If the instrument is dropped into water or gets wet, wipe it using soft cloth. Do not heat to

dry it.

The instrument has a dust-proof and waterproof structure i.e., the instrument does not

malfunction even when immersed in water of 1 m depth for 30 minutes. This does

guarantee non-destructive, trouble-free, dust-proof, and waterproof performance in all

situations.

When replacing the batteries or when a serial cable connected, the instrument does not

have the dust-proof and waterproof performance. The dust-proof and waterproof

performance is maintained only when the covers are attached correctly.

After replacing the batteries or removing the serial cable connected, make sure that the

waterproof gasket attached to the cover is not deformed or discolored, or has foreign

matter adhering to it. If the waterproof gasket is deformed, discolored or has foreign matter

adhering to it, dust could get inside, water leaks could occur that could lead to instrument

malfunction.

To disconnect an electrode or serial cable, hold the connector and pull it off. If you pull at

the cable, it may cause breakage.

The phono jack communication between the instrument and a personal computer (referred

to as PC in the rest of this document) may fail because of environmental conditions, such

as electromagnetic noise.

Do not replace the batteries in a dusty place or with wet hands. Dust or moisture could get

inside the instrument, possibly causing instrument malfunction.

Do not use an object with a sharp end to press the keys.

If the power supply is interrupted while measurement data is being saved in the instrument,

the data could be corrupted.

A Ni MH rechargeable battery can be used in this instrument.

Operational precautions (battery)

Do not short circuit a battery.

Position the + and side of the battery correctly.

When the battery has depleted or the instrument will not be used for a long time, remove

the batteries.

Of the specified battery types, make sure to use two batteries of the same type.

Do not use a new battery together with a used battery.

Do not use a fully charged nickel-metal hydride battery together with a partially charged

battery.

Do not attempt to charge a non-rechargeable battery.
