The battery slot in the front of the unit accepts the 10.8 V Lithium-Ion rechargeable battery provided.
Survey time with a fully charged battery is approximately 3 hours. Batteries are recharged with the
optional battery charger or by simply leaving the battery in the unit and connecting the unit to a standard
AC source and leaving the system in standby mode. Time to recharge a battery is approximately
4-5 hours. Be sure to keep the battery slot cover on the unit while in use to ensure that no dust or dirt
enters the unit’s interior.
On the back edge of the unit, the SIR 3000 has six connectors and one slot for the memory card. The five
top-row connectors are, from left to right: AC Power, Serial I/O (RS232), Ethernet, USB-B, and USB-A.
Data can be stored on Compact Flash cards, USB key drives (Compact Flash format), or
IBM Microdrives for transfer to PC for processing. These cards are widely available and are the same
type used in other digital devices such as cameras, MP3 players, and camcorders. The amount of system
card memory is totally dependent on your choice of memory card size.
Since radar profiles can sometimes be several megabytes in size, GSSI recommends that you
purchase a high capacity card.
If there is no memory card inserted when the system is first turned on, the system will save the
data profile to its internal system memory and data will have to be transferred with the USB
connection or by later inserting a memory card. The internal memory capacity is approximately 1
gigabyte. Please see Chapter 4: Data Transfer and File Maintenance for additional information on
transfer.
The large, protruding 19-pin connector at the back of the system is for the antenna
control cable. You will notice that antenna connection on the SIR 3000 has five notches cut from the
metal. These mate with the five raised nubs on the control cable to ensure that the pins line up properly.
Screw the cable connector collar onto the SIR 3000 to make proper contact. The cable should
only be
hand-tightened
.
Do not use a wrench
to tighten the connection as over-tightening will
result in damage. The cable connector collar should be screwed down far enough to cover the red
line on the SIR 3000 connector.
The only proper time to attach or detach an antenna is with system power off. Be sure to unplug
any external power and to remove the battery before attaching or detaching antennas. Putting the
SIR 3000 in Sleep Mode is not sufficient.
:
Use of a Model 3207 pair (100 MHz) or a Model 3200 Multiple Low Frequency antenna
without a TR fiber optic link will cause damage to the SIR 3000’s transmit circuitry. Always be sure to
use a Model 570 Fiber Optic Transmit Link with the Model 3207 pair and use the fiber optic transmit
cable for the 3200 MLF.
