5.22  Security code:  

CodE

Access to the instrument configuration menu may be
protected by a four digit security code which must be
entered to gain access.

New instruments are

configured with the default security code

When all the digits have been adjusted

press

)

to return to the

CodE

prompt. The revised

security code will be activated when the Rate
Totaliser is returned to the totalisation mode.

Please contact BEKA associates sales department if
the security code is lost.
