SM06 Rev. 4.10 Tac/Com Control Head Manual
3.11 Master Edit Mode
USE THIS MODE WITH GREAT CARE.
SERIOUS PROBLEMS CAN DEVELOP IF THIS MODE IS USED INCORRECTLY,
RESULTING IN SEVERE CHANNELING DIFFICULTY.
This mode is intended for service related activities, but is presented here briefly for
reference, and to aid with any field related data problems. Normally, there is no reason
to ever enter this mode unless it is necessary to change a frequency display for some
non-agile channel, such as a guard.
Note: Master Edit Mode is seldom used in normal operation.
If the data in the control head has developed an error that cannot be edited out, this
mode will correct these problems. Such problems may be:
Garbled or incorrect channel number, or out of sequence numbers.
Mystery characters in a space that can't be reached for edit.
Incorrect guard or crystal channel data.
