Menu D : Self-diagnosis
Self-diagnosis display shows the internal temperature
of the transmitter and the failure description.
d-1 AMPTMP : Internal temperature of the transmit-
ter
• Press the key on the screen
c
to display the
screen of internal temperature of the transmitter (
d
).
When a temperature alarm is issued, “TEMP” is
changed to “ALM.”
(This corresponds to “AMP TMP” of “Error display of
self-diagnosis” in the following table.)
If the temperature cannot be measured due to defec-
tive internal data, “IMPOSS” is displayed.
(This corresponds to any of “RAM ER”, “PAR ER” or
“AMP EP” of “Error display of self-diagnosis” in the
following table.)
d-2 ALMCHK : Display of self-diagnosis results
