4. Put the GX-2009 in the charging base. Tabs at the top and bottom of the charging base
retain the instrument.
5. While the unit is being charged, the red charging LED on the top face of the charger is on.
6. When the charging LED turns off, the GX-2009’s batteries are fully charged. It takes
approximately 3 hours to recharge a fully discharged battery set.
7. To verify whether the batteries are fully recharged, remove the unit from
the charging base, then press the POWER MODE button to start up the
unit. If the battery icon on the LCD is fully colored in, then the unit has
been completely recharged.
NOTE:
A battery set will have a typical service life of 500 charging cycles.
When using the GX-2009, draining the batteries as much as possible before recharging them
will help maintain the maximum operating time. If the batteries are regularly only partially
drained before charging or partially charged before using the instrument, the battery may
experience a “memory effect” and the run time of the instrument may be decreased. If you
notice this effect with your instrument, use the REFRESH function described in “Discharging
the Batteries with the REFRESH Function” on page 48 to discharge your batteries before
recharging them.
