LEDs, and Switches
Refer to Figure 1-19 on page 1-80 for the location
of the keys and switches.
The following three keys allow the customer to
scroll the different options available.
1. Function
2. Service Mode.
3. Power Control
Each scrolled digit is set blinking on the panel
display.

selected digit stops blinking and the chosen option
is performed.
Any options not validated disappear after a time
out of 60 seconds.
Exit Key: Pressing this key will cancel the
scrolled option.
Power On/Reset Key: When the function
digit is '0' and service mode is '0' or '1', this key
will start a power on reset sequence followed by a
general IPL. Power On should not be pressed
until after a 10-second delay from Power Off.

down' sequence.
Unit Emergency Power Off (UEPO)
Switch: When this switch is switched down-
wards, power is removed from the machine and a
mechanical interlock locks the switch in the OFF
position. The machine can not be powered ON
until a CE resets the interlock and sets the switch
upwards which enables power ON.

the 3745 starts to power ON and turns OFF as
soon as the machine powers down. Refer to
