Important Safety Information
Caution
1. Never charge alkaline or dry cell batteries with this charger. The battery may burst and cause personal injury. Also, do not charge NiCd or NiMH batteries
with this charger.
2. Do not charge Li-Ion or LiPo batteries unless they are designed with overcharge protection.
3. Do not attempt to charge a battery without rst conrming that the appropriate charging pod is installed.
4. Disconnect charger from the power supply before installing, adjusting, removing, or cleaning the charging pod.
5. Use only charging pods and the power supply designed for the TWC6ML charger. Using similar parts available from other manufacturers may damage
the charger or batteries.
6. Make sure the contacts in the charging pod and on the battery are clean, otherwise the battery may not fully charge.
7. Do not allow wire or metal objects to touch contacts in the charging pod or any internal part of the charger.

Replacing A Charging Pod
The charging pod is made from quality materials and designed to
provide years of service when properly used. In most cases, the charging
pod will only be replaced when you want to use the charger with a different battery.
Follow these steps to change the charging pod:
1. Obtain a charging pod made specically for the TWC6ML. Conrm that the charging pod is compatible with the battery you want to charge.
2. If connected, unplug the power supply from TWC6ML.
3. Turn the locking screw on the bottom of the charging pod counter-clockwise several rotations. Lift the charging pod and the screw from the charging base.
4. Before placing the replacement pod in the charger, make sure the contacts on the bottom of the pod are aligned with the contacts in the charger. After the
replacement pod is inserted into the charger base, secure with the locking screw. Do not over tighten the screw.
5. Inspect the charging contacts in the pod to ensure they are clean and unobstructed.
6. Connect the small end of the power supply cable to TWC6ML and plug the other end into a wall outlet. You are now ready to charge a battery compatible
with the charging pod.
Charging A Battery
1. Conrm that the charging pod and battery are compatible.
2. Connect the small end of the power supply cable to TWC6ML and plug the other end into a wall outlet.
3. Place battery to be charged in the charging pod. The battery may be charged while attached to the radio. Note: If the battery is attached to the radio,
charging time will be reduced if the radio is powered off.
4. When a battery is placed in the charging pod, the charge status LED will illuminate ORANGE for a short period while the charger performs a battery
diagnostic. Once completed, the charge status LED will change to RED. This indicates the battery is charging.
5. While a battery is charging, the charge status LED will illuminate RED with no ashing. If the charge status LED is red and ashes, a fault has been
detected. The ash pattern represents a specic fault condition. See section on Fault Conditions for details.
6. When the battery is charged to 80% of capacity, the charge status LED will change to GREEN and begin to ash. It is recommended that the battery
be charged to at least 80% capacity before use.
7. The charge status LED will illuminate GREEN with no ashing when the battery is fully charged.
8. When a fully charged battery is removed, the status LED may remain illuminated for a few seconds. Allow the charge status LED to go off before placing another battery in the charging pod.
9. The TWC6ML is designed to operate at room temperatures between 15°C and 30°C. Charging batteries at temperatures outside this range may result
in under charging of batteries.
Fault Conditions
When the charge status LED ashes RED, a fault condition exists. There are three different ash patterns, each indicating a specic type of fault. The ash
patterns and fault conditions are as follows:
Flash Pattern Fault Type
Flashes 1 Time Indicates charging complete, but battery is under charged. Battery voltage is below minimum level required. This warning is
provided after the rapid charging stage is complete.
Flashes 2 Times Indicates battery contact is “open” and current is not passing through the (+) and (-) contacts on the battery. This warning is
provided after the initial diagnostic stage is complete. Check charging pod to conrm compatibility with battery.
Flashes 3 Times Indicates over-current condition caused by battery short circuit. Have the battery checked by a qualied technician. Do not at-
tempt charging the battery if a short circuit exists.
