Sound Devices PIX 220i - Manual (Page 13)

Powering
The PIX 220i and PIX 240i are powered from either removable, Li-ion rechargeable batteries or
external DC. One or two removable 7.2 V Li-ion batteries can be mounted to the recorder and used
as either primary or backup power. The PIX automatically chooses the power source based on the
voltage level of the external power supply. If the external voltage falls below the level of attached Li-
ion batteries, the unit will transition to Li-ion power. The transition between external and removable
battery powering is seamless and has no affect on recording or playback operation.
In the event that power is lost or media is disconnected during recording, the PIX recorder will recover
the file upon the next power up or drive insertion. Up to 30 seconds will be lost from the end of the re-
cording. (
See “Power Loss During Recording”, page 31 )
Removable Li-Ion Batteries
PIX recorders are compatible with Sony L-Series Li-ion rechargeable batteries. Several power capaci-
ties are available in this battery type, ranging from 1000 mAh to 7000 mAh. Larger amp-hour batter-
ies provide more run-time.
One or two L-Series batteries can be attached to the rear panel. When two batteries are attached, they
operate in parallel. A second battery increases run time and both batteries will drain evenly. Batteries
can be hot-swapped for continuous recording.
CAUTION
Danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type. Properly recycle
batteries. Do not crush, disassemble, incinerate, dispose in a fire or expose to high temperatures.
When powered by the removable Li-ion battery, the LCD displays the battery voltage of each battery.
The nominal operating voltage for Li-ion batteries is 7.2 V, with operating voltages ranging between
6.8–8.5 V. When the total voltage drops to 6.9 V, the voltage display on the LCD will begin flashing
red and the power LED will also flash red to warn that the battery is nearly depleted. When the volt-
age reaches 6.8 volts the recorder powers down—any recording in-process will automatically close
(stop).
CAUTION
The XL-WPH3 power supply must be connected to a protective earthing connection in order to ensure safety. The power
supply’s cord acts as the disconnect device. The cord must be readily accessible and remain readily operable.
