TRANSCEIVER PROGRAMMING
3-10
April 1999
Part No. 001-8170-100
Parameter Acceptable Responses Description
Companding Yes, No Programs if companding is enabled when the system is selected
(Section 2.4.3). This parameter is displayed only when the 900
MHz frequency band is selected in the Radio Parameters screen.
Home Repeater 1-20 Programs the number of the home repeater to which the transceiver
is assigned (Section 3.3.1).
Area 0, 1 “0” is usually programmed unless two or more LTR-Net or LTR
localities (sites) are close enough to interfere with each other. One
locality is then programmed “0” and the other “1”.
UID (Unique ID) 1-65503 Programs the unique ID of the mobile (Section 4.7.1). This can
also be programmed using the “Edit LTR-Net UID” screen
described in Section 3.2.3.
Status Repeater 1-20 Programs the number of the status repeater (Section 3.3.1).
Locality Number 1-1023 Programs the number of the locality (site). Each locality that a
mobile can access must have a different locality number, and the
same scheme must be used to program the mobiles and repeaters.
Roaming Criteria,
Drop out 50-100% Programs the percentage of good data messages that must be
received to stay on the current locality when roaming. The default
is 75% (Section 2.10.3). This can also be programmed using the
“Edit Auto-Reg. Criteria” screen described in Section 3.2.3.
Roaming Criteria,
Pick Up (Capture) 50-100% Programs the percentage of good data messages that must be
received to initiate registration on new locality when searching for
a new locality is occurring. The default is 80% (Section 2.10.3).
Transmit Inhibit Block 1-239 Programs the transmit inhibit block of ID codes. If a code within
this block is decoded up to 5 seconds before the PTT switch is
pressed, the transmitter does not key (Section 2.9.5).
Block Decode 1-239 Programs a block of ID codes that are decoded regardless of the
group selected (Section 2.9.2).
Fixed Priority 1 and 2
ID Codes 1-239, 240, 241 [1] Programs the Fixed Priority 1 and 2 decode codes if they are used
(Section 2.9.1).
Call Light Yes, No Programs if Call indicator is enabled when a call is detected on the
ID code (Section 2.4.2).
Preferred Locality 1-5 Number of a programmed
locality Programs the localities that are searched first when locality search
is initiated. Preferred Locality 1 is checked first, Locality 2 second
and so on. Not used localities are programmed “0” (Sect. 2.10.3).
CHANNEL INFORMATION
Number 1-20 The active repeaters accessed by the system are assigned to
numbers 1-20 (Section 3.3.1).
Channel 1-840 (800 MHz)
1-479 (900 MHz) Programs the channel number of each active repeater (Section
3.3.2). Inactive repeater numbers are programmed “0”. Channel
numbers are listed in the table at the end of this section. Use the
programming channel number, not the FCC channel number.
Offset (-12.5 kHz) Yes, No For channels 1-600, programs if they are offset 12.5 kHz on the
low side (Section 3.3.2).
GROUP INFORMATION
Selectable
Groups (1-10) 1-239, 240, 241 [1] Programs the selectable decode (receive) and encode (transmit)
IDs (Sections 2.9.3 and 2.10.1). Both IDs in a group must be pro-
grammed. With the standard model (w/o telephone keypad), only
the system/groups programmed for the quick select switch (see
Section 3.2.3) are transferred into the transceiver (Section 2.5).
Call (Indicator) Yes, No Selects if the call indicator is enabled when a call is received on the
group (Section 2.4.2).
[1] 1-239 = Standard group calls, 240 = Auxiliary calls, 241 = Telephone calls (see Sections 2.9.3 and 2.10.1).
