Chapter 7. POWER SOURCES
A Li-ion battery
provide main power source. A Lithium battery is used to back up the system
real time clock and content in the RAM memory when the main power source is not available.
NOTE.
When using the PT630 for the first time, the main battery must be charged
for 3 hours
.
The PT630 checks the power level of the main battery when the portable terminal is in use;
however, the backup battery is only checked during power-on-test. Both low battery conditions
will be signal to the user by a warning message on the LCD.
When the main battery reaches a low condition, the LCD flashes a warning Message (“Main
Battery Low”) at one minute intervals while the portable terminal is on. The main battery can
continue to supply power in normal operation for approximately
10~30 minute
However, the
level may reach the PT630 power cutoff point and automatically turn the Portable terminal off.
In this situation, the lithium battery continues to back up data and application programs in RAM
and the PT630 cannot be powered up until the main battery is recharged or replaced.
