Miscellaneous Keyboard MODs         by Andrew Litt, KC5APJ

1. INIT Reset- The normal memory clear mode described in the manual
   doesn't reset all of the stored functions, just the frequency
   memories. To clear everything, including the APO timer, TOT, and
   any keyboard mods, hold down  [REV], [A/N], and [F/W] while turning
   the radio on. The radio will say INIT on the display for a second,
   and then everything will return to factory default.

2. Slashed zeros- Hold down [A/N] while turning the radio on. All
   zeros will be slashed. Repeat the sequence to disable slashed zeros.

3. Memory only tuning- If you want to restrict tuning to memories only,
   hold down [D/MR] and [A/N] while turning the radio on. The display
   should read CH-xx, with the xx being the last memory that was tuned
   to before the mod. Tuning with the knob or the microphone buttons
   only changes to the memory number shown after the CH-. Pressing
   [CALL] puts CALL on the display and tunes to the call channel. The
   only features that can be changed in this mode are power level,
   lock, and code paging. All other functions such as APO, backlight
   brightness, and repeater offset are not accessible in this mode,
   and must be changed in normal operating mode. Exiting this mode is
   done in the same way as getting into it: hold down [D/MR] and [A/N]
   while turning the radio on. This mode is probably designed for a
   commercial version of this radio.
