1.5 Operational safety
There are two important points to remember re-
garding the operational safety of your CYPRES 2:
1. CYPRES 2 self-tests automatically every
time it is switched on. After every switch-on
procedure, CYPRES 2 executes a self-test
routine that checks all key internal functions.
A successful self-test gives you the best pos-
sible assurance that your unit will provide
trouble-free operation for up to 14 hours.
When the display unit shows , the self-
test has been successfully completed. If the
self-test has detected an error or discrepancy,
CYPRES 2 will not enter normal operating
mode but instead will switch itself off after dis -
playing an error code indicating why the self-
test process has been aborted (see Section 5).
2. CYPRES 2 has a fail-safe error detection sys-
tem. Two processes are activated in CYPRES 2
once the unit has been switched on: a primary
operational process and an independent con-
trol process that continuously monitors the
operational process. Should an error occur while
the operational process is active, the backup
control process should switch the unit off.
Depending on the type of error and its potential
impact, CYPRES 2 can either be switched on
again or it will remain permanently in shut-
down mode. With certain error codes (see Sec-
tion 5) the user will be unable to reactivate the
unit. In these cases, CYPRES 2 must be sent
to the manufacturer or to your service center
for inspection and adjustment.
A malfunction can cause a false activation/failure
to activate: Any technical device can fail. Every fault
imaginable can happen with the CYPRES 2 including,
but not limited to: displaying a faulty status, failing to
function, or functioning at the wrong moment or in the
wrong circumstances. Such a failure could easily injure
or kill you or others. If you or your friends or relatives
are unwilling to accept these uncertainties and risks you
must not use CYPRES 2.
