2.2. Turning on the DSA-1
The DC input connector is on the front right-hand corner of the instrument under the
front-panel legend `DC IN'. Connect the DC adapter to the mains, and plug its output
into the unit's DC input connector.
Switch on the DSA-1 by pressing the [ON] key. If all is well the 'CHARGE' indicator will
light, followed shortly afterwards by the 'ON' indicator.
The display will contain the message:
Prism Sound
DSA-1 sw2.0 hwC
This message indicates that version 2.0 of the DSA-1 firmware is installed, and that the
DSA-1 hardware is at revision C. If a later version of firmware has been installed, at
the factory or elsewhere, the current version will be displayed instead of V2.0 as above.
The READ.ME file on the system software diskette will also contain information about
the current firmware version and revision level.
If battery operation is required, then the battery may first need to be charged; this will
take approximately 12 hours in fast-charge mode. The battery charge mode must first
be selected and this is described in section 6.9.5. While operating on external DC
power the unit will trickle-charge the battery.
If no test input is connected (and if the Generator is off), all indicators in the DATA
display panel will be unlit and in the CARRIER panel the 'FAIL' indicator will be lit.
If the behaviour of your DSA-1 is not as described above then contact Prism Media
Products or your distributor.
