General Charging Guidelines

  Completely discharge Ni-Cd batteries before you charge them.  Repeated
  partial discharging and recharging can shorten their useful life.  This
  does not apply to Ni-MH batteries.

  It is normal for batteries to become warm while charging.

  You cannot charge two 9V batteries and AA/AAA batteries at the same
  time.  However, you can charge one 9V in the right 9V bay and AA/AAA
  batteries in the left bay.

  You cannot charge only one AA or AAA battery in one battery bay.  You
  must always charge a pair of the same size and type batteries in one bay
  if the other bays are empty.

CAUTIONS:  Never mix AA and AAA batteries in the charger, or put a
           discharged battery and a charged battery in the same bay.

           Do not attempt to charge any other size or type battery than
           those for which this charger was designed.

           Charge batteries where the ambient temperature is between 60
           and 85 degrees F. (16 and 29 degrees C.).  Batteries do not
           fully charge when cold.  If the charging conditions are too
           warm, the batteries can permanently lose their rechargeable
           properties.

Charging Batteries

The charger has 4 charging bays.  Each bay provides charging spaces for 
two AA and two AAA batteries in alternating spaces.  The AA batteries fit 
between flat spring contacts while the smaller AAA batteries fit between 
flat spring contacts along the compartment's upper side and spring metal 
loops along the lower edge of the compartment.

Note:  The indicators light steadily while batteries are charging.  If the
       indicators flash, at least one of the batteries you are trying to
       charge is defective.

Follow these steps to charge the batteries.

1.  Lift the battery charger's cover.

2.  Place 2 AA or AAA batteries in BAY 1 according to the polarity symbols
    (+ and -) marked inside the bay.  If you have more than 2 batteries to
    be charged at a time, fill BAY 2 next, and so on.

    To charge 9V batteries, place the first battery in the 9V channel
    across BAY 1 and BAY 2.  Slide the battery's connectors onto the
    terminals on the outside wall of the channel.  Place a second 9V
    battery in the channel across BAY 3 and BAY 4.

3.  Slide BAY to select the number of bays being used specifically for
    AA/AAA batteries.

    CAUTION:  Before connecting the charger to AC power, be sure all
              batteries are correctly installed according to polarity.
              Incorrectly installed batteries (polarity reversed) will
              not charge and can be damaged.

    Notes:  When you charge 9V batteries, the position of BAY has no
            effect.  The charger's built-in timer tracks the state of
            charge.

            To charge one 9V battery, use the left (BAY 1 and BAY 2) 9V
            battery channel.

4.  Insert the AC adapter's plug into a standard AC outlet. The indicators
    on top of the charger light showing that the batteries are charging.

    Note:  If the indicators do not light, try one or more of the
           following suggestions.

             Check the battery positions in the bay, and reverse any that
             are incorrect.

             Remove the batteries and clean the batteries' and charger's
             contacts.

             One or more batteries might be defective.  Replace any
             defective batteries.

5.  When the charging indicators turn off, the batteries are fully
    charged.  Unplug the adapter from the AC outlet and remove the
    batteries.

    WARNING:  To prevent damage to your charger and risk of shock, always
              unplug the AC cord from the AC outlet before you remove or
              replace the batteries.
