Safety Instructions

4)
1) Adapter Cup Safety Features:
a. Every Impact Charger adapter cup has circuitry in the base of the charger cup and is designed
to have 2 pre-set voltage limits: a high or maximum level, and a low or minimum level.
This helps protect against any power surges coming into the charger from damaging
the batteries or charger circuit board.
b. If the voltage is below the minimum pre-set voltage, the charger goes into trickle mode until
the voltage of the battery gets high enough for rapid charging.
c. If the voltage is above the pre-set maximum voltage, the charger will shut down and no
charge will be put into the batteries.
2) Charger Circuit Board Safety Features:
a. Ambient Temperature cut-off is set at 90°C (176°F). Charging will be cut off when the charger
reaches 90°C (176°F). It will resume charging when the temperature goes down below
65°C (149°F). The red LED will blink 4 times and then stops for 22 seconds. It will repeat
itself until the temperature drops down.
b. The circuit board is outtted with a fuse to protect against any power surges into the charger
and will trip the fuse before the surge reaches the circuit board.
3) Power Supply Unit (PSU) Safety Features:
a. Over Power Protection Circuit:
If the charger software determines there is too much power, it will cease rapid charge and
go into standby mode.
b. Over Current Protection Circuit:
If the charger software determines too much current is being applied to the batteries,
the charger will cease rapid charge and go into standby mode.
c. Short Circuit Protection Software
d. Over Thermal Protection Circuit
Impact Universal Chargers utilize our fully interchangeable cup system to support most
new and discontinued two-way radio batteries. All units incorporate individual micro-processors
that fully and safely support NiCd, NiMh, Li-Ion and LiPo battery chemistries. The charger can
charge rechargeable batteries of different capacities, from 700mAh to 5000mAh.

Charger Voltage Ranges:
Lithium battery charging = 7.2V – 8.4V
NiCd and NiMh battery charging = 7.2V – 9.6V
Power-On Self Diagnostic Feature:
When the charger is plugged in and powered on, it will automatically check the power
circuit in each charger bay, indicated by the red LED going on, then off within 1-3 seconds.
If there are no batteries inserted in the charger, the charger bay LED’s will be steady clear
indicating standby/idle mode. If batteries are inserted into the charger, the red LED will be solid
for 1-3 seconds and then stay solid red to indicate rapid charging cycle or change to solid green,
indicating the batteries are fully charged.
Charger LED Light Coding:
Steady Red = Battery is charging.
Flashing Red = Battery Fault.
   4xredashes= The ambient temperature of the charger is too high for charging.
6xredashes= The voltage of the battery being charged is too low for rapid charge mode.
The charger will automatically go into trickle charge mode until
the voltage is high enough, at which point the charger automatically
changes to rapid charge mode.
8xredashes = The voltage of the battery is too high, and the charger will not charge.
Remove the battery for use on the radio.
Steady Green = Battery charging is complete.
LED Light Off (with battery inserted) = The battery’s internal protection circuit has been tripped.
LED Light Off (with no battery inserted) = Charger is in standby/idle mode or the charger unit
is powered off.
Technical Information

(9
1) “My batteries do not appear to be charging or holding a charge.”
If batteries being inserted into the chargers have no LED light reaction, check to ensure the charger
and battery contacts are clean and that the battery charging contacts and charger contacts are properly
aligned. If LED light behaviour appears to be normal and your batteries seem to have no capacity
even after being fully charged indicated by steady green LED’s, completely discharge them, then fully
charge them again. If they still do not retain a charge (or very little), new batteries must be purchased.
2) “The charger does not power up when plugged in.”
a. Ensure that the power switch is turned on.
b. Unscrew fuse holder and check fuse. Replace with the same 15amp fuse if necessary.
c. Check that power cables are inserted rmly into cable ports and that the power to the wall
plug or vehicle DC receptacle is on or functioning properly.
d. Ensure that all charger adapter cups are fully inserted and charging contacts are touching
and aligned with the chargers contact points.
3) “LEDlightisashing red.”
This indicates a fault with the battery. Check the bay using another battery. If the bay operates
correctly, the battery is not charging suciently and will need to be replaced.
4) “LED stays red, then goes green, then off.”
Some Li-Ion batteries have internal protection breakers that send a message to the charger to turn off
when the battery is fully charged. The battery will be charged and ready for use. If the battery is left in
the unit for an extended period, the charge level of the battery will decrease, and the charger will begin
charging automatically. To restart charging cycle, attach battery to radio, power radio for minimum of
5 minutes and then reinsert battery. The charge cycle will begin charging automatically.
5) “One (or more) bay(s) is not working, the LED lights are not illuminating at all.”
To determine if the fault is in the charger or just the cup, remove the cup from the non-working bay
and swap it with a cup in a bay that is working correctly. If the same bay LED is still not illuminating,
then the processor for that bay may be faulty. If the faulty bay has moved to the bay that was previously
working, the cup is possibly defective. Contact your authorized Impact dealer for assistance.
6) “MyMotorolaCP150/200batterydoesnottintheMOT-11cup.”
There is a built-in spacer in the oor of the cup. Carefully remove the spacer by pulling the edges
away from the side walls of the cup. Turn the spacer around 180 degrees and re-insert.
Troubleshooting Tips

Important Information
PLEASE READ CAREFULLY BEFORE USING
YOUR AC/DC-3 CHARGER
The single metal pin inside the bottom of each charger bay is designed to detect Li-Ion and Li-Po battery
chemistries and apply the correct charging algorithm to avoid any overheating issues. It is therefore
necessary to ensure that the four sensor pin contact holes are always exposed when charging Li-Ion
batteries. When charging NiMh or NiCd chemistry batteries, please cover the access holes with the supplied
adhesive strip or electrical tape to ensure maximum charging performance.
Your charger is factory set for charging Li chemistry battery packs.
