Tri-Tronics Pro 500 G2 - Manual (Page 9)

Charger Light Function
The cradle flashes red and then green briefly when power is applied.
When the collar is charging at full current, the cradle light will be red.
When the system switches to trickle charge, the cradle light will be
green. The collar is now fully charged but may be left on charge. If
the cradle light is off, power is interrupted, there is no collar on the
cradle, or the collar is not properly connected.
Cradle Charging Contacts
Jack for AC Power Supply (“Wall Cube”)
Use only the wall cube supplied by Tri-Tronics
with the charging cradle.
Important: If the cradle light blinks red slowly when the
receiver is in the cradle, please consult the troubleshooting
section of this manual.
Charging System
(Two-Hour Recharge)
The new cradle charging system keeps your receiver batteries in
better condition than any previous charging system we’ve used. The
charger charges rapidly – only two hours are needed.
NiMH batteries do not have a “memory” so you can recharge at any
time, even if the batteries have not run down. Also, you can leave the
unit (or battery pack only) on charge in the cradle at all times when it
is not in use, without damage to the batteries.
To recharge, plug the supplied wall cube into household AC power
and plug the wall cube cord into the cradle. Insert the receiver into
the cradle so that the receiver charging contacts line up with the
cradle charging contacts. There will be a positive “snap”
feel when the receiver locks into the cradle correctly.
Do not charge batteries in especially hot
areas such as inside a vehicle that is parked
in the sun.
Keep the vents on both sides of the charger free
of dirt and debris. Do not block the vents.
The cradle comes with two screws and
may be mounted on a wall.
Battery care tips:
• Charge batteries at room temperature. Allow cold
batteries to reach room temperature before charging.
• If the receiver charging contacts are very dirty, wash
the collar with clean water before charging so that
good contact with the charger can be made. Note
that the charging cradle is not designed to get wet.
• Use only the wall cube we supply.
• If the unit is in storage, recharge every four months,
and recharge prior to first use.
