7.6.2 Operator Controls
The combo charger has no operator controls or power switch.
7.6.3 Using the Combo Charger With The 7535
• Gently slide the 7535 into the cradle portion of the combo charger until
lightly latched. An icon is displayed indicating that the 7535 is properly
installed in the combo charger – .
The battery charge LED on the 7535 lights up indicating that the unit has external
power and battery charging may begin. It is safe to leave the 7535 in the combo
charger cradle while it is not in use – the battery will not be overcharged.
7.6.4 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 0˚ C and 39˚ C
(32˚ 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. The 75%
charge indicator is handy if you need a quick recharge – a quick charge often takes
less than one hour.
