2.13 TEST FUNCTIONS
With the standard LTR-Net operating code, there
is no test mode that can be selected to perform testing.
To manually control the transceiver with this code,
program temporary conventional channels. When the
test operating code is loaded, several test functions are
available. Refer to Section 5 for more information.
To display the software version number, turn
power on with PTT switch pressed. The version
number is displayed as “VER x.xx” (see Section
2.3.10). If any error codes are present (see next
section), the most recent error code is displayed
instead of the software version.
2.14 ERROR CODES
2.14.1 GENERAL
If error conditions occur during operation that
interrupt normal program execution, reset occurs
which usually restores normal operation, and informa-
tion on the error condition is stored. Up to 11 error
conditions can be stored. If more than 11 occur, the
first 10 continue to be stored and only the 11th code is
overwritten so it is always the most recent code. An
error condition can be caused by such things as a
defective memory chip or other hardware problems or
software problems.
When power is turned on after an error condition
has occurred, “ CODE xx” is briefly displayed (see
following example). The “xx” indicates the latest
unread code.
To display the most recent error code, turn power
on with the PTT switch pressed and then release it. To
mark a code as read, press FCN CLR. A beep then
sounds and the next code is displayed if applicable.
Once all stored codes are marked as read, they can no
longer be displayed and “ CODE xx” is not
displayed at power up. However, they continue to be
