Pressing the [Action] control performs an operation similar to the

Charging ST4ex/ST4i
Your ST4ex/ST4i contains two rechargeable Lithium Polymer batteries that are charged
when you plug in the AC Adapter. You will not need to replace the batteries. Just leave
the ST4ex/ST4i connected to the AC Adapter for one to two hours. To confirm that the
battery is fully charged, check the LED status (Power indicator): RED & GREEN for
CHARGING and GREEN only for FULLY CHARGED.
● Connect the AC Adapter to the AC Adapter Terminal and turn on the wall socket
switch.
● Charging starts automatically as soon as you attach the AC Adapter. The green
power indicator will turn on once it detects AC power.
● The red power indicator will turn on if charging is in progress, and turns off when
charging is completed.
● It takes about one to two hours to be fully charged.
● The time required to be fully charged may be longer for the first time.
● Turn off the wall socket switch and remove the AC Adapter after charging is
completed.
Be sure to use the AC Adapter to charge the Rechargeable Battery Pack(s)
if the unit has been left unused for a few days. Your device will not operate
properly before charging the batteries. The embedded Backup Battery will
be fully charged when the AC Adapter or Rechargeable Battery Pack is
present.
