3. OPERATING INSTRUCTIONS
3.1 BATTERY POWER
The SONOSAX SX-R4 recorder can be internally powered by 6x rechargeable Nickel Cadmium (NiCd) or
Nickel Metal Hydride (NiMH) AA-Cells (LR6), or disposable Lithium batteries.
WARNING:
Conventional dry cells such as Alkaline batteries should not be used to power the SX-R4 as
they could lead to unexpected powering Off
NOTE:
The running time highly depends on the battery type (NiCd, NiMH or Lithium), the kind of
microphone being used and whether the 48V Phantom is turned On. It also depends on the
number of tracks being assigned and the sampling frequency
3.1.1 Opening the battery compartment
To open the battery compartment located on the rear of the unit, press on both locking pins on each side of
the compartment and slide out the battery holder. Insert 6x AA-Cells (LR6) and check for correct polarity.
WARNING:
Never leave discharged batteries in the compartment. To ensure an optimal running time,
use only premium quality rechargeable cells and check the expiry date
3.1.2 Closing the battery compartment
Slide the battery holder into its compartment. Its shape is designed so it can not be reversed. Press firmly but
without excessive force on both side of the battery holder to securely lock the pins.
3.1.3 Battery Low alarm
When the average voltage per cell reaches 1.05 Volt, an alarm is displayed on the LCD screen and a bip tone
is heard in the headphone. This alarm indicates that the SX-R4 still have a running time of approx 10 to 20
minutes. When the voltage reaches 1.0 Volt per cell then the SX-R4 will automatically turns Off, thus
protecting your rechargeable batteries from excessive discharge.
NOTE:
If a recording is in progress, the SX-R4 will stop the recording and then properly save the
recorded file on the hard disk before turning Off.
3.2 EXTERNAL DC POWER SUPPLY
SX-R4 Recorder can be powered from any regulated external DC power source from 6 to 18 Volts. The DC
source must be capable to sustain at least 1,5A under 12 Volts DC. The average power consumption is
approx 4 to 7 Watts depending on the microphone powering and the configuration of the SX-R4.
