SX-M2 USER MANUAL
Never leave batteries or accumulators in the battery compartment when the
SX-M2 is not in use for several days.
Use only top quality batteries.
4. OPERATING WITH BATTERIES OR ACCUMULATORS
Move the "POWER" switch to the left. After 2 to 3 seconds, the "ON" led at the
center of the front panel will flash every 3 seconds.
5. LOW BATTERY WARNING
The "ON" led will flash every second when the total battery voltage drops to 14
volts. (See AUTONOMY)
6. AUTONOMY
The autonomy of your SONOSAX SX-M2 is proportional to the type of
batteries/accumulators, and the kind of microphones used. The table below shows
different figures (each 48V microphone uses 2mA) :

7. EXTERNAL POWER
The SONOSAX SX-M2 can also be powered from an external DC source, from 12
to 24 Volts, via the "DC IN" connector.(Battery powering is automatically disabled
once an external DC source is used.) Once the external power supply is connected,
the SX-M2 may then be operated as when powered by batteries or accumulators. If
the "ON" led flashes normally (every 3 seconds), the external voltage is between 14
to 24 Volts. If it flashes every second, the external voltage is below 14 Volts.
Polarity : + = center, - = outside collar
