PSDS Operational Inputs and Accessories
SAFETY NOTICE: Power down the radios and disconnect (unplug) the PSDS power
from the AC power source prior to connecting or configuring any of the following
optional inputs or accessories.
LS-671 External Speaker Operation
The PSDS provides for the use of an external LS-671 for the radio net. There is a
connector labeled LS-671 on the back of the PSDS. This connector allows the user to
use a standard CX-13292 cable and LS-671 speaker. The user plugs the cable into the
PSDS and the LS-671 speaker. One end is marked for the speaker; therefore, care
should be taken to ensure the cable is connected correctly.
Periodic Maintenance
Maintenance Safety Notice
Power down the radios and disconnect (unplug) the PSDS power from any AC power
source prior to the performance of any maintenance actions.
Air Filter Maintenance
On the bottom of the system you will find two fan covers that have filters. Depending on
the environment these filters will need periodic cleaning. Included with the PSDS are
several replacement filters. When replacing the filters, wash the filters removed from the
PSDS in warm soapy water, rinse thoroughly and allow to air dry. Filters should last
indefinitely. The PTS recommended filter cleaning interval is 14 days of continual
operation.
Filter Removal Process
• Turn the system onto its rear/back
• Snap the 2 covers holding the filter assemblies off from the bottom of the chassis
• Remove each filter assembly
• Snap out the filter retainer from the assembly to access the filter for cleaning or
replacement
• After cleaning the dirty filter or replacing worn filters, insert the clean or new filter
in the assembly and snap the retainer back into the filter frame
• Replace the assembly in the PSDS and snap the cover back in place
• It is recommended that the unit not be run without Filters to prevent internal
damage
