Transmission Range
The Transmitter and Receiver have a nominal range of 100 metres.
The actual distance achieved will vary depending on atmospheric condi-
tions, the position and type of nearby obstacles (such as walls, trees, or
metal objects) and the state of the battery
Moving the Receiver just a few centimetres can sometimes make a big
difference to the strength of the signal, so to obtain the best reception, we
suggest you move the Receiver around to find the best location by trial and
error.

Cleaning the Nest Box
Once a year, after the nesting season has finished and all the birds have
left the nest, we recommend that you clean out the Nest Box and dispose
of all nesting material and unhatched eggs etc. Under UK legislation, you
can only remove unhatched eggs between August and January. If you
remove any eggs you must dispose of them.
To do this, take the side off the box (as explained earlier) and carefully
clean the box, the side panel itself and the camera with a soft cloth or
brush, being especially careful with the camera lens.
Take out any nesting material from the nest box and throw it away, and
wash out the box with hot water (being careful not to get the camera or
connectors wet). With the side open, leave it for a day or two to dry out,
before shutting the box , and putting it back in position.

Pictures at Night
At night, or when completely dark outside the nest box, the only source of
light in the nest box will be the infra red lights fitted on the camera. Under
such conditions, the camera will give an image which is dimmer than the
image in brighter light such as daylight, and consists of shades of grey,
just like a black and white picture. This is perfectly normal. We use infra
red lights at night so that you can continue to see a picture, but, because
birds cannot see infra red, their natural sense and rhythms of day and night
are not affected.
Because of the dimmer pictures at night, we suggest that you turn the
brightness on your TV (or computer) up at night to get a better picture.
