3.1.2 Inserting and Removing a SIM Card
)
• Keep the card dry.
• Use it only within the specified temperature range.
• Do not bend the card.
• Protect the card from direct impacts.
)
Failure to follow these instructions could result in data loss and/or permanent
damage to the card.
Caution Always ground yourself to remove any static charge before touching the CPU card.
The electronic devices are sensitive to static electricity.
Precautions:
1) Only experienced personnel should open the mechanical housing of the tablet
computer.
2) Use a grounding wrist strap all the time.
3) Place all the electronic components in a static-dissipative surface or staticshielded bag when they are not in the chassis.

3.3 Batteries
Battery power
system
The CS25 tablet computer is designed to work with two removable battery packs
placed inside the battery pack compartment. The fully charged battery packs provide
several hours of battery life, which can further be extended by using power management features through the BIOS setup. The system includes power management
software which allows the battery to report the amount of charge percentage left in
the battery. Refer to "4.2 Hot Tab Software Utility Functions".
3.3.1 Operating Principles
Charging / firsttime use
• The battery must be charged prior to using it for the first time because it is delivered with an energy content as low as possible.
• The permissible temperature range for charging is between 0°C to +40°C/ +32°F
to +104°F. For optimal charging, we recommend charging the batteries at a low
ambient temperature of +10°C to +20°C/+50°F to +68°F if possible.
• It is normal for the battery to become warm during charging. Using the chargers
recommended by Leica Geosystems, it is not possible to charge the battery if the
temperature is too high.

26
CS25, Operation
• For new batteries or batteries that have been stored for a long time (> three
months), it is effectual to make only one charge/discharge cycle.
• For Li-Ion batteries, a single discharging and charging cycle is sufficient. We
recommend carrying out the process when the battery capacity indicated on the
charger or on a Leica Geosystems product deviates significantly from the actual
battery capacity available.
Operation /
Discharging
• The batteries can be operated from -20°C to +55°C/-4°F to +131°F.
• Low operating temperatures reduce the capacity that can be drawn; high operating temperatures reduce the service life of the battery.
