HEAT VENTILATION
Vents are built into the case to allow hot air to escape to help keep the electronic circuitry cool. This helps to maintain
accurate operation and maximize the lifespan of the charge itself.
A built-in cooling fan helps to keep the charger cool during operation. This will help extend the service life of the charger
and allow it to function more accurately and effi ciently.
CAUTION: Do not block the vent holes or cooling fan during
operation, as it could cause the charger to overheat and possibly cause permanent damage.
