Safety Precautions
If you are using this instrument for the first time, make sure to thoroughly read “Safety Precautions,” on pages 7 to 14.
Do Not Remove the Case
Do not remove the case from the instrument. Doing so is extremely dangerous. For internal inspection, adjustment and battery
replacement, contact your nearest YOKOGAWA dealer.
Unplug If Abnormal Behavior Occurs
If you notice smoke or unusual odors coming from the instrument, immediately turn off the power, unplug the USB-AC adapter, remove
the battery pack and contact your nearest YOKOGAWA dealer.
Handle the USB-AC Adapter and USB Cable Properly
Do not place objects on top of the USB-AC adapter or USB cable, and keep them away from heat sources.
General Handling Precautions
Do Not Place Objects on Top of the Instrument
Never place objects such as other instruments or objects that contain water on top of the instrument. Doing so may damage the
instrument.
Do Not Subject the OTDR Port or VLS Port to Mechanical Shock
If the optical connectors or universal adapters are subjected to mechanical shock, they may be damaged. The instrument may not
perform measurements correctly due to damage or deformation that is not visible to the naked eye.
Do Not Scratch the LCD
Because the LCD can be easily scratched, do not allow any sharp objects near it. Also, do not apply vibration or shock to it. Do not apply
strong shock to the LCD or place objects on top of it.
When Carrying the Instrument
First, remove all cables including the USB cable and optical fiber cable. When carrying the instrument, grasp the protector or the
attached strap firmly.
