10. Operating the Balance with the Battery
This function can be used only when the balance is battery-operated.
10.1 Specifications
• Built-in nickel-cadmium battery
•
Charging time:Approximately 12 hours
•
Drive time:
Approximately 32 continuous hours
•
Number of charge/discharge cycles: 300 or more
10.2 Charging Method
※While the balance is battery-operated, [
] stays on. The indicator flashes [
] (charging required) when battery
capacity decreases. If the balance flashes [
], charge the battery by following these steps:
(1) Connect the dedicated AC adapter to the balance.
(2) Turn the balance off.
(3) Charging takes approximately 12 hours, with power switched off. Charging the battery longer than 12 hours
decreases battery life.
10.3 User Precautions
1.
Once charging is complete, use the balance without the AC adapter to avoid over-charging. This can occur since
the balance continues to charge the battery with a weak current when the power is switched on. Overcharging will
also decrease battery life.
2.
When the balance is used for the first time after purchase, the operating time may be shorter than when using a
fully charged battery. This is due to natural discharge of the battery. Although the balance can be used while
[
] is flashing, it should be recharged as soon as possible.
3.
When the battery displays no indication, or an indication disappears quickly after the balance is switched on,
battery capacity is low. In these cases, either charge the battery immediately or plug in the AC adapter.
4.
Charging the battery while [
] is displayed reduces battery life.
