SYSTEM STATUS AND ALARM DISPLAYS
The PCM 1024Z System provides you with a
number of indicators and displays to show you
that your system is operating correctly. This sec-
tion will explain each display's function
EXT MEM ERR display
This display blinks when a data error occurred
during transmission of data between the trans-
mitter memory and the memory module. Turn
off the power. DO NOT REMOVE OR INSERT
THE MEMORY MODULE WITH THE POWER
TURNED ON. THIS ACTION COULD DE-
STROY THE MODULE.
ON AIR display and beep
This display is turned on when radio waves are
being transmitted.
Enter ID No. display
This display indicates when the security mode
is set. In this case, model data cannot be
changed. See the section on data protection to
reset this display.
LOW BATTERY display and beep
This display and warning beep are to notify the operator
that the transmitter battery is low.
TO PREVENT PROBLEMS, LAND THE MODEL
AS SOON AS POSSIBLE.
PLL ERROR and beep
This display blinks and sounds when the synthesized
frequency
module is removed during
operation.
Be sure to turn off power before installing the module.
Do not remove or insert the module with power on.
(D BACK-UP BATTERY FAILURE - DO NOT FLY
This warning is displayed when the data stored has been
lost for some reason. A beep will sound simultaneously.
When the power switch is turned on again, the error dis-
play goes off and the data returns to the factory default
state. The lithium data backup battery needs to be re-
placed, or there is a fault in the system. Return the
system to the Futaba service center for assistance. The
life of the lithium battery varies, but is usually at least
five years.
2 CURRENT MODEL I S * * * ##.NAME * * *
This display shows the model number and model name
currently stored in the active area of the transmitter. It
will disappear a few seconds after the system is turned on.
DATA PAC IS MISSING - LOADED MODEL1
This message is displayed whenever the transmitter is
turned on with the memory module removed and the
active model data was stored on the module. Without the
desired model data, the system loads the Model 1 data
instead.
3 CAUTION: NON-DEFAULT COND IS ACTIVE
This warning message is displayed, and a beep sounds,
whenever the transmitter is turned on with a flight con-
dition switch activated. This display and alarm will turn
off as soon as the flight condition switch is turned off.
4 CAUTION: SPECIAL MIX FNCT IS ACTIVE
This message and alarm are activated when the transmitter
is turned on with a mixing switch activated. The alarm
monitor above the power switch also blinks. All of these
will stop as soon as the mix switch is changed to its OFF
position.
CAUTION: ENGINE CUT FNCT IS ACTIVE
If the power is turned on with the engine cut switch on,
this message is displayed and a beep sounds. When the
engine cut switch is turned off, the display and alarm
stop.
