Safety guide
 Do not expose the battery to high temperature such as fire, heat, direct sun, etc.
 Do not connect the positive and negative terminals of the battery together with any metal
objects such as wires, paper clips, etc.

Do not expose the battery to any type of liquid such as rain, water and salt water, etc.
 Do not disassemble or modify the battery.
Storage guide
Lithium Ion batteries continue to slowly discharge (self-discharge) when stored or not in use for a while.
In this case, you need to:
 Remove the battery pack and store it separately from the product in a cool and dry location
without direct sun light on the pack or its carton box.

Store the battery at temperatures between 10 °C and 30 °C (50 °F and 86 °F) to minimize the
deactivation effect of the battery.
 Storage at the temperatures above 30 °C or 86 °F reduces the battery storage life.
 Charge at least once per 6 months to prevent leakage and deterioration in performance
caused by self-discharging.
Battery charge status indicator
You can find the indicator for battery charge status on the battery pack.
Table 1 Battery charge status
Indicator Description
Voltage < 9.0 V, immediate charge required
Remaining Capacity Alarm, immediate charge required
1 to 19% Remaining, charge before storage
21 to 40% Remaining, charge before storage
41 to 60% Remaining, charge before storage
61 to 80% Remaining
81 to 100% Remaining
Electrostatic discharge precautions (ESD)
This instrument was manufactured in an ESD protected environment. Semiconductor devices used in
this product are susceptible to damage by static discharge. Depending on the magnitude of the
discharge, semiconductor devices may be damaged by direct contact or mere proximity of a static
charge. This may cause performance degradation, early failure, or immediate destruction. Use the
following guidelines to prevent ESD damage:
 Before connecting a cable to this instrument terminal, short circuit the center of the cable with
an outside metal shield.
