To prevent electrical shock or fire, be sure to use the supplied power cord. The main power plug can only be plugged in an outlet with a protective grounding terminal. Do not invalidate protection by using an extension cord without protective grounding.

Power Supply

Ensure that the source voltage matches the voltage of the power supply before turning on the power.

Safety Precautions for Using Ni-Cd Battery

Storage

• Please remove the Ni-Cd batteries from the main unit when storing.

• Do not leave the batteries in a hot-temperature environment such as under direct sun light, inside an automobile, or near fire, because this leads to leakage of the alkaline electrolyte.

• For long-term storage (6 months to 2 years), select a location where the humidity is low and the temperature is in the range from 10 to 25 °C.

• When charging for the first time after long-term storage, deactivation of the reactants may have led to decreased battery capacity, but this problem is restored after several cycles of charging and discharging.

• When storing the batteries for more than 6 months, please charge or discharge then recharge the batteries at least once per year to prevent leakage and the decline of performance.

Battery Life

The time of operation of the batteries gradually decreases with repeated use, even when the batteries are fully charged. Though it depends on the condition of use, take 2 years or 500 times as a measure to have the batteries replaced. (A typical battery life is 2 years or 500 times.) Please also note that prolonged storage leads to shortened battery life.

Charging

• Do not charge the batteries in any other instrument.

• Only charge batteries that are completely discharged. Charging batteries that are partially charged results in overcharging. This shortens battery life.

• Avoid overcharging the batteries, because this leads to shortened battery life.

• Charging the batteries for a long time may cause leakage of gases and electrolytes.

WARNING

• Do not disassemble or alter the batteries in any way. The electrolyte inside the batteries is strong alkaline which can damage skin and clothes. Be especially careful of the electrolyte entering the eye, because it may cause blindness.

• Never short the batteries. Heat generated by the batteries may cause burns.

• Never heat or throw the batteries into fire. The batteries can rupture or the electrolyte may spray out.

• Never put water on the batteries or immerse them in water. Such actions can cause heat to be generated or lead to rusting as well as the loss of ability to function.

• Do not use the batteries in any other instrument. The difference in the specification can cause damage to the other instrument.

• Do not pull the cable of Ni-Cd battery back or connector with excessive force.
