The Dogtra 3500X uses a lithium polymer battery.
Recharge the unit if the indicator light is red or does not
come on, the transmitter LCD shows only 1 bar on the
indicator, or the system will not stay on when any button
is pressed.
NOTE 1:
Only use Dogtra-approved batteries, chargers,
and accessories for your Dogtra e-collars. This will
prevent any damage that can be incurred from
attempting to use a different charger.
NOTE 2:
The unit has a partial charge when it leaves
the Dogtra facility. Upon receipt of the system, be sure
to give it a full 2-hour initial charge before the first use
away from any flammable substances.
NOTE 3:
When a charger is not in use, disconnect it from
the power source. Fully charge the batteries if the unit
is to be stored without use for a period of 3 months or
more.
