Hazard Warnings

Warning! Power Rating. The UW-7’s main power input must be connected to

an external power transformer that provides voltage and current within the specified

rating for the system.

Use of an incompatible power transformer may produce electrical shock and

fire hazards. See Specifications and Optional Accessories in Chapter 2.

Warning! Internal Voltage. Always turn off the power switch and unplug the

power cord before cleaning the UW-7’s outer surface.

Warning! Liquids. Avoid spilling liquids on the digital scale; fluid seepage into

internal components creates a potential shock hazard. Do not operate the

instrument if internal components are exposed to fluid. Use a soft cloth to wipe

off any spilled water.

* Warning! Unauthorized user modifications or application beyond the

published specifications may result in electrical shock hazards or improper

operation. Bowles Corporation will not be responsible for any injuries

sustained due to unauthorized equipment modifications.

* Warning! Changes or modifications to this unit not expressly approved by the

manufacturer could void the user's authority to operate the equipment.

Precautions

The following precautions are provided to help you avoid damaging the system or

creating inaccurate readings:

Caution: Service. Authorized service personnel should service the UW-7. Only

qualified technical personnel should perform troubleshooting and service procedures on

internal components.

Caution: Environmental Conditions. Do not expose the system to temperature

extremes during operation. Storage ambient temperatures should remain between 10 -

35C (50-95° F). System operation should be at approximately 21 c (70 F) performance

may be adversely affected if temperatures fluctuate above or below this range. Allow 45

minutes for unit to reach room temperature.

Caution: Use of cell phones in close proximity to the unit may cause readings to

vary slightly.

Caution: Do Not Immerse. Clean only with a mild detergent, and wipe down with

a gentle cloth.
