CHARGING THE BATTERY
Insert the cable of the power supply into the power jack at the back of the charger. You
can determine it is the power jack because it is the only hole in the charger that will
accommodate the cable from the power supply.
Insert the power adapter into the applicable AC 110 Volt power outlet. The three LED
lights will flash for about one second and then the green light will stay on indicating
everything is normal.
Turn off the radio and insert the radio into the charger. It is assumed the battery is already
attached to the radio. Make sure that the terminals on the battery and the terminals in the
charger are reliably in contact with each other. When that happens the red LED will be
turned on and the radio is being charged.
After about five hours of charging, the red LED will be off and the green led will be on,
indicating the battery is fully charged.
When the green LED is on you can remove the radio from the charger and unplug the
power supply from the AC 110 Volt power outlet.
If the yellow light is flashing, there is a problem with either abnormal charging
temperature or some circuit problem. The radio should be removed from the charger and
the power supply going to the charger should be unplugged.
This radio can accommodate either part number KB-70A or KB-70B. The KB-70A is a
nickel-hydrogen battery and the KB-70B is a Li-polymer battery.
When the radio is first bought, or being left unused for at least two months, the battery
might be discharged and the battery should be charged. It might take a few times of
charging to reach an optimum charge. The battery should be charged at least once every
three months.
When the battery is fully charged it is best to remove the battery from the charger for
optimum life of the battery. The battery should not be recharged if it is fully charged.
Charging should not begin until the status on the radio shows low battery.
If using the nickel-hydrogen battery, when the radio enters the low battery alarm status,
the battery should be recharged before continuing to use the radio. Using the radio
excessively after the radio enters the low battery alarm status will affect the life of the
battery.
The Li-polymer battery has an internal protective circuit that will cut off the battery
power when the radio is in the low battery alarm status mode. When the radio is first
placed in the charger, the red LED will not turn on for about one to five minutes. After
that delay the charging indicators will turn normal.
