OPERATION  
Always use a battery pack until it can  
no longer provide the necessary pow-  
er.  
Follow these steps to charge a battery  
pack.  
1. Slide the battery connector of the  
battery pack you want to charge  
into the CHARGING JACK.  
Cautions:  
• This charger works only with 4.8-  
volt, 7.2-volt and 9.6-volt nickel-  
cadmium battery packs. Charging  
other types of battery packs could  
damage the battery packs.  
(illus)  
• Be sure the battery pack is rated at  
4.8 V, 7.2 V, or 9.6 V.  
• Avoid charging fully-charged bat-  
tery packs. Doing so can damage  
the battery pack or cause it to lose  
some of its storage capacity.  
Warning: Connect or disconnect  
the battery plug only when the AC  
cord is disconnected. Otherwise,  
arcing and burning might result.  
• Charge battery packs only at room  
temperature (65-80×F). Charging  
battery packs in hot areas can per-  
manently reduce the battery pack’s  
power capacity.  
Notes:  
• If the connector does not fit, turn  
it over and try again. Do not force  
it.  
To protect battery packs, allow  
them to cool for 20 minutes before  
recharging them.  
• If you want to charge a 4.8 volt  
nickel-cadmium battery pack,  
plug the small end of the sup-  
plied adapter cord fully into the  
battery pack’s connector. Then  
plug the adapter cord’s large end  
fully into the CHARGING JACK.  
• Charge only one battery pack at a  
time.

in  
the  
battery  
(illus)  
• If the battery pack you want to  
charge is a new one or has not  
been used for more than 3  
months, leave it in the charger  
for 24 hours, even if the  
CHARGE indicator turns off.  
Caution: Be sure to insert the bat-  
tery pack into the upper side of the  
comprtment first. Then secure the  
battery pack in place so it pushes  
down the applicable voltage selec-  
tor sensors and the two latches at  
the lower side of the compartment.  
• If the CHARGE indicator flashes,  
check the battery connection.  
4. When the CHARGE indicator turns  
off, unplug the charger’s AC cord  
then disconnect the battery pack.  
3. Plug the AC cord into a standard  
AC outlet.  
Notes:  
• High-capacity 7.2-volt, 1700  
mAh, and 9.6-volt, 950 mAh bat-  
tery packs might require two  
charging cycles to fully charge.  
(illus)  
• When you disconnect a 4.8-volt  
or 9.6-volt battery pack from the  
compartment, be sure to take  
out the lower part of the battery  
pack first.  
Notes:  
• After 7 seconds, the charger  
automatically selects the appro-  
priate charging current.  
• When you disconnect a 7.2-volt  
battery pack from the compart-  
ment, take out the upper part of  
the battery pack first.  
• The CHARGE indicator lights  
when the battery pack is charg-  
ing, automatically turns off when  
the battery pack finishes charg-  
ing, and flashes when the bat-  
tery pack fails to charge.
