NOTICE
To avoid the possibility of malfunction/ damage to the
product, damage to data, or damage to other property, follow
the notices below.

Handling
• Do not use the instrument in the vicinity of a TV, radio,
stereo equipment, mobile phone, or other electric devices.
Otherwise, the instrument, TV, or radio may generate noise.
• When you use the instrument along with an app on your
smart devices, such as a smartphone or tablet, we
recommend that you enable “Airplane Mode” on the device
to avoid noise caused by communication. When turning on
airplane mode,
Bluetooth® settings may be turned off.
Make sure that the setting is turned on before use.
• Depending on the condition of surrounding radio waves,
the instrument may possibly malfunction.
• Do not expose the instrument to excessive dust or
vibrations, or extreme cold or heat (such as in direct
sunlight, near a heater, or in a car during the day) to prevent
the possibility of disfiguration, damage to the internal
components, or unstable operation.
• Do not place vinyl, plastic, or rubber objects on the
instrument, since this might discolor the instrument.

Maintenance
• When cleaning the instrument, use a soft and dry/slightly
damp cloth. Do not use paint thinners, solvents, alcohol,
cleaning fluids, or chemical-impregnated wiping cloths.

Saving settings
• Edited settings are lost when you turn off the power to the
instrument. This also occurs when the power is turned off
by the Auto Power Off function (page 22). Save the settings
to the instrument, or a USB flash drive (page 27). However,
the settings saved to the instrument may be lost due to
some failure, an operation mistake, etc. Save your
important settings onto a USB flash drive (page 27). Before
using a USB flash drive, make sure to refer to page 23.
• To protect against settings loss through USB flash drive
damage, we recommend that you save your important
settings onto a spare USB flash drive as a backup file.
