System operation
This chapter describes the procedures for normal system operation.
There are two different settings for the JCU – Original and Alternative
– with somewhat different functions for the joystick and the keypad but-
tons. The setting is made in the Setup – Maintenance dialog box, see sec-
tion 7.6.1.6. The functions for both the Original and the Alternative set-
tings are described in the tables below.

Starting up the system
Step Action
1 Verify that all cables are connected and fastened properly.
2 Verify that nobody is close to the system. Turn on the system with the ON/OFF switch on
the Power Box or Power Supply unit.
3 The red status indicator on the JCU ashes while the connection is being established. A
steady light indicates that the connection is OK.
4 The TV camera is ready to use after about 30 seconds.
The IR camera is ready to use after cool down, which typically takes several minutes. A
test pattern is displayed until the IR image appears; Figure 11.1. Meanwhile, adjust the
monitor until all 16 levels of the test pattern are visible (use the brightness and contrast
controls on the monitor).
5
Verify that the lens cover of the IR camera is open. If not, press the
C + buttons to
open the lens cover or open it manually with the handle on top of the camera.
6 Press and hold down the PRK button for 3 seconds to activate the Pan/Tilt unit.
NOTE: For start up in cold weather, see section 11.6.
