CAUTION
Before using the scale, please adhere to the following safety guidelines:
●Verify Voltage Compatibility: Ensure the power adaptor's input voltage
matches the outlet's output voltage. If not, do not plug in the adaptor; contact
your dealer instead.
●Charge Before Use: For first-time use, charge the scale for at least 8 hours by
plugging the main adaptor into the wall outlet.
●Retain Packing Materials: Save packing materials for future transport.
●Avoid Unauthorized Repairs: Only perform troubleshooting as listed in the
TROUBLESHOOTING section; do not attempt to open the unit.
●Clean Properly: Use a soft, damp cloth and mild detergent if necessary. Avoid
using harsh materials, acetone, volatile solvents, thinner, or alcohol.
●Avoid Pressurized Water: Do not clean with a pressurized water nozzle.
●Store Horizontally: During transport or long-term storage, keep the scale
horizontal.
●Remove Platter for Storage: Before transport or long-term storage, remove the
platter.
●Dry and Clean Storage: Always store the scale in a clean, dry place.

CHECKWEIGHING APPLICATION
The SEK series scales provide a checkweighing function that enables users to define,
save, and recall specific high and low weight limits. Here's how to use these features:
Setting HI-OK-LO Limits:
High Limit: Input the desired high limit using the numeric keypad, then press the
HIGH LIMIT key to save.

Low Limit: Input the desired low limit using the numeric keypad, then press the LOW
LIMIT key to save.
Note: These settings are retained in the system memory even when the power is off
and are separate from the SEK's 10 other memory sets.
Managing HI-OK-LO Limit Data:
Saving to Memory: After setting the HI-OK-LOW limits, press and hold the M+ key,
then enter a number (0-9) following the screen prompt. This will save the data to a
specific memory location.
Recalling from Memory: Press and hold the MR key, then enter the corresponding
number (0-9) following the screen prompt. This will recall the HI-OK-LO data from the
saved memory location.
By integrating these features, the SEK series scales offer enhanced flexibility for
applications that require consistent weight monitoring against predefined limits.
