============================================================
CPU Production Firmware Version 1.2 release notes:

- This is the user loadable version of the Factory 1.2 CPU firmware.  
  Will display as "uP Appl Ver:U1.2" after loading and is identical to  the
  factory "F1.2" load.

- Please use with DSP version 1.2 or higher, otherwise some features
  may not operate properly


New features:

- Added brief ScanList tag and "ON vs OFF" display when toggling  ScanLists 
  on/off.  This is displayed for >= 500 mS, depending on how large the 
  toggled ScanList is

- Added find by lockout status F1:"L/Out" feature to the PGM EDIT FIND menu
  for objects that have the permanent lockout set.

- Added a low duty cycle battery icon blink (200 mS on, 1300 mS off)  when
  battery charge is active (yellow vs black battery holder is not  detected)

- Added a "Is Mobile" bit to remote control Get Status PC/IF command -  bit 5
  of byte 1 (the byte with the RF squelch, mute, and DSP pin states).   This 
  will be described in additional detail within the updated user manual

- Added FUNC+F1 to Sweeper and Limit Search. Allows access to alternate  function
  that is not visible when a signal is being received (in Sweeper:  toggles band;
  in Limit: enters the Limits menu)

- Added within a TSYS object a "Check All CCs" option for  MultiSite=STAT.  If
  selected, on every SCAN mode pass, will force a check of all CC  frequencies
  instead of stopping after the 'dwell' time expires.


Fixes / Enhancements:

- Improvements to P25 control channel message processing, particularly 
  on non-800 MHz systems

- Improved control channel hunt speed, should result in significant speed
  improvements for MultiSite STAT and ROAM trunking systems with large  control
  channel lists

- Corrected an issue where, in certain programming configurations, custom 
  P25 trunking table information from one system could corrupt the stored
  values for another system

- Fixed channel selection menus in channel-based search objects

- Fixed CTCSS/DCS menu items (malfunction when F3 is pressed)

- Fixed Sweeper lockup when moving from All Bands to Public Safety, with 
  certain combinations of "enabled groups"

- Changed default "EndtoneMot" value from 250 to 80.  The value 80 is used
  to correct squelch tails at the end of voice transmissions on narrowband
  EDACS systems

- Corrected minor discrepancies in Motorola 3600 trunking 800 MHz default
  and splinter tables

- Improved AM unmute delay to prevent audio pops when squelch opens on AM 
  transmissions. Uses current PGM FUNC GLOB "SweepAMDelay" parameter
  [150 mS])

- Minor corrections to help text for "SweepAMDelay" and "SweepFMDelay"

- Fixed MultiSite=Stat mode problem, if active CC is the first one in the
  TSYS control channel list it was never checked

- Changed GLOB menu's "default scan list" item to allow entries up to 22
  (for Fav [Scan List 21] and SkyWarn [Scan List 22]), changed all  areas of radio
  operation that allow a numerical scanlist value to be specified to  allow values
  up to 22,  allows Fav and SkyWarn to be specified as valid Scan Lists in
  addition to the normal Scan Lists 01-20

- Fixed issue with EDACS CCDump in Analyze mode, and corrected the order of the 
  EDACS messages dumped within each two-message block

- Changed Mot 3600 Site ID display format (analyze mode) to decimal

- Fixed issue with CONV object delay time early expiration when  priority check hits
 
- EDACS I-Call 00000 problem fixed
 
- Fixed blinking '000' in DCS Search mode menu item
 
- Fixed Sweeper "All Bands" group 9 text
 
- Fixed Sweeper line 1 display when toggling bands while "paused"
 
- Fixed up/down key in SCAN mode when stopped on Wx Priority (1050Hz detected)

- Fixed Private Call TGID display format in PGM menus

- Fixed P25 CC quality display percentage "%" formatting in analyze mode

- Fixed issue where a PSR-500 or PC application may not properly clone to a
  PSR-600

- Improved Tune mode ability to properly detect and display EDACS-Narrow 
  control channel information

- Fixed source / target radio ID display for P25 user-to-user ("private") calls.
  They were swapped previously. This is primarily a user interface issue, 
  and did not affect the operation of the scanner.
