CONFIGURATION MODE

The system is configured when it is first installed by your avionics
installer. Configuration items include the Mode S aircraft address,
the interface to the other aircraft systems, the aircraft category, and
the pre-programmed values for VFR squawk code. To view or
change these settings you must use Configuration Mode.
Do not use Configuration Mode in flight. Check
with your avionics installer before changing the
configuration.
To enter configuration mode, hold down the FUNC button while
switching on the transponder. Configuration items can be changed
using the numeric buttons (6 for down, 7 for up) and the ENT button
to accept the selection. Pressing the 2 button will move back to the
last menu item. Pressing FUNC advances to the next configuration
item.
When configuration is complete; switch the transponder off. When it
is switched back on the transponder will use the new configuration.

1.10 LOW TEMPERATURE OPERATION

The KT 74 is certified to operate down to -25°C; however under cold
operating conditions, the display update rate may be slowed but
functional. The KT 74 incorporates an integral heating element in the
front panel to automatically raise the temperature around the display.
During cold operating conditions, a warm up period of 5 minutes
minimum is suggested.
