SECTION 3 OPERATION
3.4.5 SELECTING SYSTEMS AND GROUPs
The last sentence in this section was changed to
read:
When “0” is programmed, the transceiver
remains in the last selected mode until power is
cycled. The default mode is then selected.
3.8 LTR FEATURES
Receive-Only Groups
Receive-only groups are available with LTR
operation as well as conventional operation. To
program a receive-only LTR group, simply select an
encode ID of “0”.
3.8.3 RECEIVE PRIORITY ID CODES
Transmit Disable On Block IDs
Each bank can now be programmed so that trans-
mitting is inhibited while a call is being received on a
block ID code. This operation is selected on the
Create/Edit Bank screen by programming “Inhibit
Transmit During Block Decode = Yes”. The trans-
mitter can be keyed immediately after the call is
complete (there is no 5-second delay as with the
transmit inhibit feature). When this parameter is
programmed “No”, the transmitter can be keyed while
receiving a call on a block ID. This feature is available
with operating (Flash) software Version 211 or later,
and programming software version 210 or later.
SECTION 4 PROGRAMMING
TABLE 4-1 Main Radio Parameters Screen
(Page 4-19)
New Volume Set Parameter
A new “Digital Volume” parameter has been
added under the status definitions. TABLE 4-2 Create/
Edit Bank Screen
Parameters Screen (Page 4-21)
New Inhibit Transmit On Block IDs Parameter
A new parameter has been added to automatically
disable the transmitter while receiving a call on a
block ID. This parameter is called “Inhibit Tx During
Block Decode” on the Create/Edit Bank screen. Refer
to Section 3.8.3 for more information.
SECTION 7/8 PARTS LIST/SCHEMATICS
New 430-470 MHz RF Board
A revised 430-470 MHz RF board is now ship-
ping. This new board has the same parts layout as the
470-512 MHz version. However, there are many part
value changes, so a new parts list and schematic
diagram are included.
