Operating Precautions
Please carefully review all safety information about the wireless logger in
the Measurement Guide.
Bluetooth
• Do not use with systems required to exhibit a high level of safety or reli-
ability.
• Do not use in proximity to pacemakers or other medical devices.
• Do not attempt to modify or disassemble.
• When used in proximity to other devices that use the same frequency
band, for example wireless networking devices, transmission and recep-
tion of data may become unstable, or the product may be affected by the
other devices.
• The line-of-sight communications range between the Wireless Logging
Station and the Wireless Voltage/Temp Unit and Wireless Universal Unit
is 30 m. Obstructions (such as walls or metal shielding) may cause com-
munications to become unreliable and/or reduce the communications
range.
• Although communications between the Wireless Voltage/Temp Unit and
Wireless Universal Unit and the Wireless Logging Station are encrypted
using SSP, this does not guarantee the integrity or secrecy of transmitted
data. Hioki is not liable for the electronic interception or unauthorized dis-
closure by other means of measured values sent via wireless communi-
cations.
• The Wireless Voltage/Temp Unit, Wireless Universal Unit, and Wireless
Logging Station emit radio waves. Use of radio waves is subject to
licensing requirements that are specific to the country of use, and use of
these products in areas other than the countries listed in the provided
“Precautions Concerning Use of Equipment That Emits Radio Waves”
may constitute a violation of applicable law, resulting in fines or other
penalties.
To facilitate stable transmission and reception of data, the product should
be positioned away from the floor, for example on a stand, rather than
close to the floor.
