To prevent electrical shock, disconnect the AC to DC adapter from the mains before
cleaning. Use a dry cloth or one slightly dampened with water to clean the external
case parts. Do not attempt to clean internally.
When the FieldFox is connected to the AC/DC adapter, position the adapter so the
power cord is readily accessible. The power cord is the disconnecting device. It
removes main power to the AC/DC adapter. The FieldFox front panel switch is only
for the DC power within the instrument, and not for the AC/DC adapter. Alternately,
an AC switch or circuit breaker (which is readily identifiable and is easily reached by
the operator) may be installed and used as a disconnecting device to remove mains
power from the AC/DC adapter.
To avoid overheating, always disconnect the FieldFox from the AC/DC adapter
before storing the FieldFox in the backpack.
If you prefer to leave the FieldFox connected to the AC/DC adapter while inside the
backpack, you can disconnect the AC/DC adapter from its AC power source to
prevent overheating.
The AC/DC adapter has an auto–ranging line voltage input – be sure the supply
voltage is within the specified range.
The AC/DC adapter is for indoor use only.
Never use a modified or damaged charger. Use the original AC–DC adapter ONLY.
The AC/DC adapter is designed for use in Installation Category II and Pollution
Degree 2 per IEC 61010 Second Edition.
If charging batteries externally, use the optional external charger available from
Keysight, or another SMBus charger of level II or higher.
Never use a non–SMBus charger because the battery issues commands over the
SMBus to the charger to control the charge rate and voltage.
Never use a modified or damaged charger.
