respond to your transmission. It sounds when you
release the PTT switch, and you may partially hear this
tone.
Proceed Tone - This tone consists of two beeps and it
tells the landside caller when to enter the five-digit
number specifying the mobile being called. Dialing of
this number must be started within 5 seconds of hear-
ing this tone, and a tone-type telephone must be used.
2.12.4 DISPLAY MESSAGES
The following messages appear in the display to
indicate various operating modes and error condi-
tions. Selected system/group information appears in
this display during normal operation (see Section
2.3.4).
72xx6xx - On power up, the last seven digits of the
transceiver part number (see Section 1.3) are displayed
on the top line very briefly. For example, a UHF
430-470 MHz, LTR-Net transceiver is indicated as
“7243633”. The eighth display digit is reserved for
future use and is always blank.
CODE xx - Indicates that an error condition has
occurred. It is displayed very briefly at power up (see
Section 2.14).
BUSY - Indicates that the LTR-Net/LTR radio system
is currently busy (see “Busy Tone” in Section 2.12.1).
CALL SVC - Indicates that the transceiver has been
totally disabled by an over-the-air message from the
system operator. To return the transceiver to service, it
must be reprogrammed (see Section 2.9.6).
DSBL BSY - Indicates that the transmitter is disabled
by the conventional Transmit Disable On Busy feature
(see Section 2.11.3). It also indicates that the transmit-
ter was keyed while receiving an LTR call.
FCN - Indicates that the function select mode is
selected by the FCN switch (see Section 2.2.4).
HSQ SRCH - Indicates the transceiver is currently on
the first pass while searching for a new locality on
which to register (see Section 2.9.4).
LCL SRCH - Indicates the transceiver is currently on
the second or later pass while searching for a new
locality on which to register (see Section 2.9.4).
NO ACESS - Indicates that the repeater system could
not be accessed, perhaps because of an out-of-range
condition. Once this indication appears, no more
access attempts are made until the PTT switch is
released and then pressed again (see Section 2.12.1).
NO PHONE - Indicates that there is no telephone
group programmed in the current system when the dial
mode and telephone group are selected by FCN
PHONE (Section 2.7.2).
NOT AUTH - Indicates that an attempt was made to
store a telephone number in a locked memory location
(see Section 2.7.5).
NOT CONV - Indicates that an attempt was made to
enable a conventional mode feature on an LTR-Net or
LTR system.
OUT-LOCK - Indicates that the synthesizer is
unlocked. The transceiver is nonfunctional until lock
is re-established.
PROG ERR - Indicates an EEPROM read error.
Check transceiver programming or the EEPROM if
this condition persists (see Section 3.7).
PRG MODE - Indicates that the transceiver is being
programmed (see Section 3.7).
SLEEPING - Indicates that the transmitter has been
temporarily disabled by an over-the-air message from
the system operator (see Section 2.9.6).
SQUELCH - Indicates that the conventional squelch
adjust mode is selected (see Section 2.11.4).
SYS SRCH - Indicates that searching is occurring for
programmed system information.
TIMEOUT - Indicates that the transmitter has been
disabled by the Time-Out Timer (see Section 2.4.11).
TYPE ERR - Indicates that the programming data is
incompatible with the transceiver (see Section 3.7).
