In Hold state
- if the weight is not changed, the current weight is not changed
- if the weight is changed(above the 10% of Max capa), the current weight is changed and
the Hold function is released
- Whenever unloaded states, the Hold function is released automatically
- Also you want to release the Hold function, have to press Hold key in unloaded
state certainly
-IfHoldfunctionisreleased,youcanseethemassage.
2. When the F5 is set to 01
The maximum value of weight is showed when the Hold key is pressed
If the Hold key is pressed once, the peak Hold function is started
If Hold function is released, you can see the massage .
If the Hold key is pressed again, the Hold function is released
If Hold function is released, you can see the massage .

BATTERY OPERATION
1. CHARGE
A. The rechargeable battery inside the NC scale must be charged using the
voltage which don't exceed ±10% of the voltage indicated on the adapter.
B. If the voltage for charging exceed the above limit, the battery would be damage.
C. Check if an output voltage is DC 12V 1.5A.
D. Remove ADAPTOR JACK COVER of REAR PANEL and connect
adaptor with an scale like the following figure.
E. If adaptor is connected with the scale, Red lamp is on(Power) and Charge
lamp is on(Red : charge, Green : complete charge)
F. Time of charge is approximate 4~5 hours.
G. If main power switch is off, charge is not operate.(Red lamp is blinking.)
Do check main power switch(Main power switch is located Rear panel)
2. Discharge
If you use the battery continuously, discharge time is as fallows.
A. with the backlight -> approximate 22 hours
B. without the backlight -> approximate 50 hours

3. LOW BATTERY("BAT.") SIGNAL
A. To protect over-discharge of Battery, A. To protect over-discharge of Battery,
BAT LAMP is on when battery has to be charge. (80% of full charged voltage)
B. A scale turns power off automatically below the fixed voltage
(75% of full charged voltage). You can show LobAt message before turn power off.
BAT LAMP is on when battery has to be charge.
