• The SYSTEM VOLTAGE LCD shows you the DC voltage available to the
electronics in the DSS-900-KT. The acceptable range for this display is
11 to 14 VDC. If the external source or battery voltages drop below
11 VDC, the equipment operation will be compromised.
• Whenever the unit is plugged into an active AC or DC source, the
internal batteries are being charged.
• The three LEDs in the BATTERY section of the power segment tell you
the charge status of the internal RX Battery.
CHARGING Illuminates only if either AC or DC power is being
supplied to the system and the batteries are being
charged. The batteries are always on charge when
there is external power available.
CHARGED The internal batteries are fully charged.
LOW The internal batteries need to be charged.
CAUTION 1. When the LOW light comes on, locate a new power
source immediately. The batteries will only power the
RX for 1/2-hour, even when fully charged, and you can
lose contact with the agent without further warning.
2. The DSS-900-KT is designed for AC or DC
operation. The internal batteries are for temporary
emergency use only.
