4.2 Switching CYPRES on
CYPRES is switched on by pressing the button
(pushbutton switch) four times with very short
clicks. Start the switch-on cycle by clicking the
button once. After approx. one second, the red
LED-light will glow. You must acknowledge the
red light immediately by clicking the button again.
This sequence - a click following appearance of
the red light - will be repeated two more times.
After a total of four clicks, CYPRES goes into
self-test mode.
If you do not act promptly after seeing the LED-
light, or if you push the button too soon, CYPRES
will ignore the switch-on attempt.
This four-click initiation cycle has been designed
to avoid accidental switch-on.
Once the switch-on procedure is finished, the unit
will run through its
self-test. Initially, the
display
will show the number
, and then a count-
down ending in
. When the
with
the arrow down is shown, the unit should be func-
tional for the next 14 hours. After 14 hours have
passed, the unit will switch itself off automatically.
A manual switch-off is always possible using the
button. If the
self-test is not successful, an error
code is shown for approximately 2 seconds. The
meaning of this error code can be seen in chapter 5.
The manual switch-off sequence is the same as
the switch-on procedure (click, light, click, light,
click, light, click). This routine is designed to avoid
accidental switch-off.
