6.3 Power up and standby
When the breaker connecting power to the camera is switched on,
the camera will run a boot up sequence lasting for about 1 minute,
after which the camera will be in
Standby mode.
In order for the camera to operate, you must bring the camera out
of standby mode using the camera controls.
Thermal camera standby
Standby mode can be used to temporarily suspend the thermal
camera's functions when the camera is not needed for a prolonged
period.
When in standby mode the camera:
• Does NOT provide a live video image.
• Moves the camera into its “stowed” (parked) position (lens facing
down into the camera base) to protect the camera optics.
• Engages its pan / tilt motors to hold the camera in place in rough
seas.
Note: The “stowed” (parked) position can be configured using the
camera's setup menu.

• Tilt (elevate) to ±90º relative to the horizon.

a continuous zoom function, non-stabilized variants can switch

Continuous zoom
The T470SC and T473SC have a continuous zoom color visible

magnification as the thermal camera. However, when the visible
light color camera is viewed the zoom can continue to a preset limit.
Thermal camera home position
The home position is a preset position for the camera.
The home position usually defines a useful reference point — for
example, straight ahead and level with the horizon. You can set the
home position as required and to return the camera to the home
position at any time.
The home icon appears on-screen momentarily when the
camera returns to the home position. The icon flashes when a
new home position is set.
