5.2 Opening Screen
A ‘welcome’ screen is displayed whenever power is first applied to the unit on the CDM-600L:
COMTECH CDM-600L OPEN NETWORK MODEM
TURBO: TPC/LDPC S/W VER X.X.X
For CDM-600 units manufactured before February 2005, the display appears as follows:
COMTECH CDM-600 OPEN NETWORK MODEM
TURBO: TPC/LDPC S/W VER X.X.X
Otherwise, for CDM-600 units manufactured after February 2005 with the extended IF bandwidth
feature, the display appears as follows:
COMTECH CDM-600 (E) OPEN NETWORK MODEM
TURBO: TPC/LDPC S/W VER X.X.X
If the Internal Reference Warm-up Delay feature has been enabled on the CDM-600 (CONFIG:
Æ MISC Æ WARM-UP), the ensuing countdown displays, in seconds, at the bottom right until
the warm-up period is complete:
COMTECH CDM-600 (E) OPEN NETWORK MODEM
HIGH-STABILITY REF WARMING UP: 045 SEC
During this period, the Tx Carrier is deliberately muted. At the end of the warm-up period, the
bottom line reverts to the ‘normal’ display of Firmware version, and the unit will enter its normal
operational state. At this stage, pressing any key will take the user to the top level selection screen.
IMPORTANT
If the user wishes to bypass this feature, the warm-up period may be over-
ridden at any time by pressing the
[CLR] key.
On the next page, Figure 5-2 illustrates the hierarchal structure of the front panel menu tree.
Press any key to go to the SELECT: (main menu) screen.
