Specifications

Nickel Cadmium (NiCad)
Battery Pack
The standard power source
supplied with the
KX 99 is a 9.6 volt,
720 mA hour, rechargeable nickel-
cadmium battery pack. The battery
that is shipped with the
KX 99 will not
be fully charged and should be
charged prior
to use.
If possible, the battery should be
fully discharged before recharging.
This will maintain the maximum useful
charge in the battery and avoid
"memory" problems associated with
this type battery.
A characteristic of
NiCad batteries is that they do not
hold their charge for long periods of
time such as an alkaline battery does.
Caution:
Do not store a discharged battery
pack. Battery cell polarity may
reverse making it impossible for the
battery
to fully recharge.
Do not store a battery pack where it
might be accidentally shorted. The
current capability is tremendous.
Do not crush or disassemble a
NiCad battery pack. There are toxic
chemicals inside.
Do not dispose of the battery pack
in a fire. It may explode.
Do not exceed the recommended
quick charge current. Use only the
approved chargers.
The KX 99 comes standard with
a trickle charger capable
of operating
on either 11 5V or 230V. To charge
the battery; plug the charger module
into an appropriate wall outlet and
plug the other end into the connector
marked "CHRG which is located on
top of the
KX 99. It takes approxi-
mately
12 hours to fully charge the
NiCad battery pack.
Caution: To avoid possible damage
to the KX 99 make absolutely certain
that the
7 15V/230V select switch
located
on the trickle charger is in the
correct position for the voltage
to be
used.
The amount of time that the
NiCad battery pack will power the
KX 99 on one charge depends on a
number of factors:
The duty cycle (amount
of time the
unit is transmitting versus time
receiving
a signal versus squelched
standby operation). Transmitting
discharges the battery fastest.
The volume level of the received
signal.
The temperature.
A colder battery
will not last as long.

The following table shows the
approximate life of a fully charged
NiCad battery at several different duty
cycles with midlevel volume and the
battery at room temperature.

Alkaline Battery Pack
An optional replaceable cell
alkaline battery pack is available for
the KX 99. Alkaline batteries are used
for radios that are maintained for
emergency purposes because they
have extremely long shelf life and no
maintenance is required.
