4.2.3 Turn On Delay
The 6000 is CDRH Compliant with a user programmable turn on delay. The default
turn on delay is three seconds, but is user programmable from 0 to 30 seconds. The
delay setting is in the system configure screen, which can be reached by pressing the
MENU
button, followed by the
Config
soft key, then the
System
soft key. The field
is labeled
On Delay
.
4.3 The Laser Connectors
On all laser modules, except the MOPA, a 9-pin female D-connector is used for input
and output connections, as shown by the pin-out diagram below. See Figure 12 for an
illustration of the back panel.
