• Visually inspect the charger for possible damage.
• Install the IEC power cord and apply power.
A green LED in the lower-right corner of the front panel lights to indicate that power is pres-
ent. The charge LED flashes momentarily at powerup. The charger is now ready for
operation.
6.6.2 Operator Controls
The combo charger has no operator controls or power switch.
6.6.3 Using the Combo Charger With The 7535 G2
• Gently slide the 7535 G2 into the cradle portion of the combo charger until lightly
latched. An icon is displayed indicating that the 7535 G2 is properly installed in the
combo charger .
The battery charge LED on the 7535 G2 lights up indicating that the unit has external power
and battery charging may begin. It is safe to leave the 7535 G2 in the combo charger cradle
while it is not in use—the battery will not be overcharged.
6.6.4 Charging The Spare Battery
• Install the battery with the latch facing towards the rear of the charger—slide it between
the guide rails until it lightly latches in place.
The LED for the slot lights up immediately. A solid yellow LED indicates the battery is
being charged. A flashing yellow LED indicates that the battery temperature is outside the
acceptable charge range between 5° C and 39° C (41° F to 102° F).
A fully discharged battery normally takes between 1.5 and 4 hours to charge. When the
battery capacity reaches 75%, the LED flashes green. When the battery is at full capacity,
the indicator turns solid green.
The combo charger stops applying power to the battery when it is fully charged—there is no
risk of overcharge if the battery remains in the charge slot (however, see Important note,
below). The 75% charge indicator is handy if you need a quick recharge—a quick charge
often takes less than one hour.
Important: The spare battery slot is not intended as a battery storage pocket. Storing
batteries in the combo charger for extended periods (more than a week or
two) is not recommended. Lithium-ion batteries permanently lose capacity
if they are maintained at full charge for long periods of time. See the battery
storage recommendations in “Storing Batteries” on page 42.
