Position: this deliberate repositioning of the panel away from the sun further reduces

the light falling on it, allowing the mechanism to be deactivated confidently and with a

reduced risk of possible 'accidental' re-activation by the residual sunlight; 3) the Standby

Position provides a 'fail-safe' orientation for solar harvesting, should the device require

more charge than is available in its battery to operate its motors.

BEHAVIOUR

Although the device has been designed to be more reliable than the weather, it may

occasionally behave in unexpected ways. For example, in temperate locations, on

bright, windy days, the sky is often filled with small, fast-moving clouds. On such days,

the device – while performing its initial calibration run – may be confused by the rapid

changes in light caused by the passing clouds, and may therefore mis-calibrate, causing

its panel to face in a sub-optimal direction. Should this occur, simply repower the device

by switching it off and then back to 'Auto': this will cause the device to perform a new

calibration.

The amount of light required to activate the device is inversely proportional to the

amount of charge it has in its battery: less charge requires more light, and vice versa.

This is convenient because it allows the device to perform according to its capabilities:

for example, with more charge in its battery, the device can 'afford' to engage in more

'speculative' attempts to track the sun. However, these speculative attempts may cause

the panel to face in 'unusual' directions. For example, on an overcast day when the sun

is not actually visible, the device may nonetheless power-up and subsequently calibrate

according to the brightest part of the sky, which could simply be the location of the thin-

nest cloud or the largest 'gap'. When this occurs, the device will likely and quickly shut

itself down again, as there will almost certainly be insufficient solar energy available to

warrant its operation. On such days you may choose to disable the device to conserve

energy.

HINTS, TIPS, TROUBLESHOOTING

• If the device is used to power other equipment while it is charging and the power

consumption exceeds the device's power capacity, the device will eventually and as a

precaution cause its Head to retreat to its Standby Position in order to prevent possible

motor malfunctions. If this occurs, simply disconnect the equipment being powered. This

will allow the device to recover and subsequently it will begin to function normally once

more.

• When assembled, the device's solar panel is always connected to the internal battery,

therefore the device can obtain and store solar energy even when the device itself is

deactivated. This feature can be exploited to recover the device in the event that the

internal battery has become so depleted that it is unable to deliver even the very small

amount of power required to operate the device's microprocessor. In this unlikely event,

just a few minutes exposure to sunshine with the device switched 'Off' ('0') will be suffi-

cient to provide the device with the power it needs to function normally when activated.
