Self Tests

Many internal functions are tested each time the unit is powered up. If any of
these self tests do not meet tight
performance limits, a message will be
displayed similar to the following:

The unit will then switch off.

It is possible that a temporary condition caused the failure and restarting the
unit may clear the problem. If the fault persists, please contact Peak Electronic
Design Ltd or an authorised agent with details of the error message for further
advice.

Please note that some internal tests cannot be performed if a low

battery warning has been displayed. This means that if there is an internal
problem, a low battery condition can prevent the error condition from
being detected. It is therefore strongly recommended that a low battery is
replaced as soon as a “Low Battery” message is displayed.
