2.4. Powering the Receiver
To check the status of the internal batteries, view the BAT LED on the receiver's front panel.
• Check the BAT LEDs for battery status. If the receiver is on and uses the battery power the
BAT LED blinks every 4 seconds:
– A green light indicates greater than 90% charge.
– An orange light indicates an intermediate charge.
– A red light indicates less than 15% charge.
– No light receiver is off.
By battery charging if the receiver is on and DC power supply is connected the BAT LED flashes
every second. The LED light indicates the same as described above.
If the battery is full charged and the receiver is connected to DC power supply the BAT LED is
solid green.
To charge the receiver internal batteries, take the following steps:
• Plug the Receiver-to-SAE cable's 5-pin connector into the power port of the receiver
(labeled PWR).
• Connect the opposite end of this cable with the battery charger's SAE connector.
• Plug the appropriate end of the power supply-to-outlet cable into the battery charger.
• Plug the other end of this cable into an AC outlet.
• Turn off the receiver by pressing and holding the power key for more than one and less
than four seconds.
• Leave overnight.
