RECHARGING THE RECEIVER’S BATTERY

Press the lock of the Power Cord Compartment Cover (11) to open, remove the power cord and insert its plug into an AC outlet. Do not press the Power Switch (1)

NOTE: To avoid long term damage to the battery, please charge the battery to full whenever the voltage is low or at least once every 3 months when not in use. It takes about 6-7 hours to charge a depleted battery. The internal charger charges quickly at first and then automatically adjusts to smaller currents as the battery become fully charged. This prevents damage to the battery if left on charging for too long.
