Care

Do not subject the unit to sharp shocks or excessive vibration. Place on a ﬂat, level surface.

Clean the unit with a damp cloth or using mild spray furniture polish. Avoid excessive liquids.

The unit is adjusted and calibrated when manufactured and should not need adjusting. Meters may exhibit some

non-linearity, more noticeable on the hours scale. This may be noticeable around the midday points where the

pointer may be a few degrees oﬀ of the indicated time. However, zero and 23 hours (or 59 minutes) should be

accurate. If they are not, then the unit can be calibrated as follows:

With the power oﬀ, adjust the ﬂat screw on the front of the meter so that the needle indicates zero.

Remove the four screws on the front of the enclosure and GENTLY lift

away the panel. It is secured by wires so cannot be completely removed

- you need to observe the meters to adjust anyway. Apply power and

enter OTA mode - however, do not upload ﬁrmware. The unit indicates

full scale. Inside the unit are screws on potentiometers marked 'Hrs',

'Mins', 'Secs' (where ﬁtted). Each of these can be carefully adjusted to

present a full scale measurement (24/60/60 as appropriate) while the

unit is in OTA mode. Make sure that the meters are oriented the same as

they are for normal operation (normally vertical). Be careful not to touch

any other parts within the unit apart from the adjustment screws.
