of the Frequency mode prior to entering Channel mode remains the same.
When in Channel mode, pressing the Transfer button will return the radio to Frequency
mode. The channel frequency will become the new USE frequency and the last USE
frequency will become the new STBY frequency. If the radio was in Direct Tune mode (See
Paragraph 3.1.3.E below) prior to entering Channel mode, pressing the Transfer button or
allowing the radio to time out will bring it back to Standby Entry.
C. Program Mode
The Program mode is entered by pressing and holding the CHAN button for longer than two
seconds. The last active frequency remains tuned and displayed in the USE window. The
last used channel number is displayed when Program mode is entered. The channel
number flashes and turning either tuning knob changes the channel number. Pressing the
Transfer button will cause the frequency associated with that channel to flash. The tuning
knobs then work as in the Frequency mode, except that between the rollover points
(118.XXX and 136.XXX) dashes are displayed. These dashes are used to de--program
channels, and to display a channel that is unprogrammed. When the channel frequency is
flashing, pressing the Transfer button will cause the frequency to stop flashing and the
channel number to start flashing at which time a new channel may be selected for
programming.
D. Program Secure Mode
Program Secure mode is used to secure or lock the frequency that is assigned to a channel
so that the frequency assigned to that channel cannot be changed. All channels or
