14.3 One Full Discharge /Charge Cycle
Upon receipt of the system and before first time usage, it is recommended that you
perform one full discharge /charge cycle. If the battery has not been used for over 2
months, you are recommended to perform one full discharge /charge cycle. It is also
recommended that the battery is stored in the shady and cool area with FCC (full current
capacity).

1. Full discharge of the battery to let the system automatically shut down.
2. Charge the system to 100% FCC (full current capacity).
3. Discharge of the system for complete shutdown.
14.4 Checking Battery Performance
The battery performance may be degraded over time, so you need to check the battery
performance periodically. The checking procedures are shown as follows:
1. Stop the ultrasound exam.
2. Connect the system to the AC power supply to charge the batteries until current
capacity is full.
3. Disconnect the system from the AC power supply to power the system by the
batteries until the system automatically shuts down.
4. The powering time of the batteries indicates the battery performance.
If the powering time of the battery is much shorter than that specified, you may replace
the battery or contact the service personnel.
NOTE: The usage life of the battery is 300 charge / discharge cycles. If the battery is
improperly used, its life may be shortened.
