BATTERY
CAUTION
To avoid risk of explosion and injury, CNB350/CNB350AS battery pack should
only be removed, charged or recharged in non-hazardous environments.
5.1 BATTERY CHARGING
To check the charge status, install the battery and press the PTT switch
while observing the BATT indicator. (see page 7)
The battery charge system (CCA250 and CWC230) supplied with the
transceiver recharges a completely discharged CNB350/CNB350AS
battery pack in about 15 hours.
Battery pack should not be charged with the supplied battery charge
system for longer than 16 hours.
The CSA280 is an optional desktop rapid charger that charges the CNB350/
CNB350AS battery pack in approximately 1.5 hours. The transceiver and its
battery can be placed into this charger, and the charger set to rapid charge.
Battery condition is automatically sensed: when full charge is achieved, the
charger switches to trickle-charge mode to maintain the charge indefinitely
without harm to either the battery or the charger. This charger and an extra
battery are highly recommended.
5.2 BATTERY REMOVAL/INSTALLATION
1. Turn the transceiver off.
2. To remove, turn the battery lock screw
counterclockwise 5 or 6 turns, and pull
the battery pack until it slides out.
3. To install, slide the battery pack into
the battery cavity until fully inserted,
and turn the battery lock screw
clockwise until hand-tightened. (see
figure 4)

CWC232 120/230 VAC wall charger.
CAUTION
Never plug the power supply to the CCA250 charge adaptor except
with a CAW240, CWC230 or CWC232.
5.4 CBT350 BATTERY TRAY
CBT350 is a battery tray that holds six AA alkaline batteries and is used
with the HX350S transceiver.
1. Push both sides of the top case and remove the bottom case.
2. Install the battery cells into the top case, paying close attention to the
battery polarity markings on the case.
n When the HX350S is operated with the alkaline batteries, the battery
life is as follows: (5/5/90 duty cycle)
• high power - 5 hours
• low power - 12 hours
Note that battery life is more than doubled if transceiver is consistently
operated on low power.
NOTE
To ensure proper alignment of screw, rotate it counterclockwise a
couple of times prior to tightening.
The battery indicator on the transceiver is only applicable to the
CNB350/CNB350AS rechargeable battery. Disregard this indication

page 18
Owner’s Manual
HX350S
5.5 BATTERY SAFETY
Battery packs for your transceiver contain Nickel-cadmium (Ni-Cd)
batteries. This type of battery stores a charge powerful enough to be
dangerous if misused or abused, especially when removed from the
transceiver. Please observe the following precautions:
DO NOT SHORT BATTERY PACK TERMINALS
Shorting the terminals that power to the transceiver can cause sparks,
severe overheating, burns, and battery cell damage. If the short is of
sufficient duration, it is possible to melt battery components. Do not place a
loose battery pack on or near metal surfaces or objects such as paper clips,
keys, tools, etc. When the battery pack is installed on the transceiver, the
terminals that transfer current to the transceiver are not exposed. The
terminals that are exposed on the battery pack when it is mounted on the
transceiver are charging terminals only and do not constitute a hazard.
DO NOT OVERCHARGE
Do not charge the transceiver for more than 16 hours with the battery
charge system. Heat generated by overcharging can shorten battery life
and cause other battery pack component failures. The CSA280 rapid
charger changes to trickle charge to maintain charge after their rapid
charge cycle. Battery packs may be left in the CSA280 chargers without
harm to either the battery pack or charger.
DO NOT INCINERATE
Do not dispose of any Ni-Cd battery in a fire or incinerator. The heat of fire
may cause battery cells to explode and/or release dangerous gases.
DISPOSE OF BATTERY PACKS PROPERLY
Ni-Cd batteries must be recycled or disposed of properly. For requirements
in your area, check with the dealer from whom you purchased your
transceiver. The symbol shown below is a reminder that the battery packs
are recyclable.
