All the functions for the standard C528 are as below. If anyone out there has
any that aren't listed, please mail to me!

                    Standard C520/C528 Modifications
                   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This file is a compendium from to others being bandied about the place. It
is hoped this will be the better of them, being the easiest to follow!

o To open up the rx only up on the unit on VHF:
  VHF F+0 F+D

o To add 320-400MHz, 400-480MHz, 820-900MHz, 900-980MHz:
  UHF F+L F+0 F+B F+L F+3 A

o To Expand Tx/Rx coverage, do both the above in that order, then:
  VHF F+6 change step to 12.5MHz A
  F+8 F+8 F+C
  Tune down to 144.9875
  F+0 F+D PTT F+8 F+C

o To Store independent transmit/receive frequency in one channel:
  Enter receive frequency into dial
  F+D <mem number>
  Enter transmit frequency into dial
  F+D F+A F+<mem number> A

o To Clear the tx assignment offset:
  F+D F+A <mem number>+A F+A A

o To Clone one set to another:
  B B F+0 F+PS    then key up on the set to clone from

Set mode key assignments:
The set mode allows a number of user parameters to be customised according
to individual taste. Set mode is initiated by pressing F+0. The following
are entered after going into set mode:

 0    Turns off the beep tones on each keypress
 F+0  Sets band edge limits, i.e. 0079=100-179, 400-479. 3060=130-160

 1    Changes count of paging operations tone, one beep or 5
 F+1  Set tx delay on carrier drop when using as cross-band repeater

 2    Enables entry of the 1kHz figure on direct keypad entry
 F+2  Stop scan on busy channel even if CTCSS doesn't match

 3    Sets mod delay on paging Tx to either 450ms or 750ms
 F+3  Switch UHF bands between 300/400/800/900

 4    Mutes short noises during squelch operation
 F+4  Keypad entry of 4 digit or 3 digit frequency

 5    Turns on and off the auto power off function
 F+5  Pager Audio Mute (Mutes any audio that follows the paging signal)

 6    Enable/Disable the rotary channel knob when keypad locked
 F+6  Fast tune (F+KNOB) gives either 1MHz steps, or 100kHz

 7    Sets the CTCSS tone frequency
 F+7  Either Dual Tone Multi Frequency, or Single Tone Frequency

 8    Sets the offset repeater frequency
 F+8  Cross Band Repeater Enable/Disable (Identified on display by a ".")

 9    Changes the LAMP button into the REV button
 F+9  Up and Down keys either act as the knob, or as 10MHz steps.
