External Power
This appendix contains instructions for converting the ADS Model
4000
from receiving power via the internal battery pack to
receiving power via an external DC power source. This conversion
requires a special kit available by special order through Accusonic
Technologies (part # 3506-0023). The monitor requires a DC
power source with a voltage between 9 and 14 volts at 1 amp of
continuous current for proper operation.
Install the conversion kit in the following way:
1. Remove the monitor chassis from the enclosure.
2. Unplug the 12-volt battery pack from the bottom of the
processor board at P6.
3. Remove the battery pack from the monitor chassis.
4. Detach the Velcro strap located at the top of the chassis.
5. Remove the I/O chassis cable from the monitor in the
following way:
Disconnect the cable from the top, right-hand side of the
processor board at P4.
Disconnect the cable from the bottom, left-hand side of the
processor board at P7.
6. Loosen and unscrew the chassis connector nut on top of the
monitor, and completely remove the I/O connector/cable from
the monitor.
