likely to take more power out of the batteries than the solar panel is putting in. If
the batteries run out, simply take them out of the battery box and charge them
separately using the mains charger. You can also run the nestbox using the mains
or single use batteries.

Adjustment of Lighting System and Focus
Before leaving the factory, the camera focus has been adjusted to a little above
the floor of the nest box. You can adjust the camera focus by turning the lens
turret. The camera is a very delicate part of the system so please do this gently,
and be very careful not to touch a finger on the lens.
The lighting system has 3 “states” or modes of operation, and whenever it is
switched on, it will always be operating in one of these 3 states.
State 1: High level: when bright external or natural light reaches the camera, the
internal lights are switched off.
State 2: Daylight: whenever the lighting system is switched on, and the camera
needs some additional light to provide a good picture, and the external light is
bright enough to indicate it is daytime, a supplementary white light is switched
on.
State 3: Night time: whenever the lighting system is switched on, and the external
light is dim enough to indicate it is night time, a supplementary infra red light is
switched on. This is invisible to human and bird eyes, so does not disturb the
birds’ natural rhythms. Although the camera continues to give a colour picture,
this form of illumination means that the TV picture looks as if it consists of
shades of grey.
The point at which the lighting system switches from state 2 to 3 has been factory
set to correspond to an average dawn/dusk. However, if your box is in a particu-
larly open, or shady location, or for some other reason if you wish you can
change this setting as follows:
1.
Choose a time when the light level outside is the level at which you want
the system to switch.
2.
Start with the system in the “OFF” state.
3.
Turn it to “CONT”, and then immediately back to “OFF”.
4.
The system should now be in “set” mode and the white light inside the box
should flash on and off 6 times to show it is waiting for you to set the
switching point. If you don’t get 6 flashes, try from step 2 again.
5.
Wait until after the 6 flashes, check that the light level is the level at which
you want it to switch every morning and evening, and then switch back to
“CONT”.
