OPERATION
CLEARING RACE PRESETS
See Figure 18.
To clear a preset RACE channel from memory:
 With RACE mode selected, press the keypad button for
the memory location you wish to clear.
 Press and hold the Backspace/Clear button for three
seconds.
 After three seconds, the frequency will be replaced by
all dashes, indicating that the preset has been cleared.
The dashes will be displayed for one second, then the
scanner will return to normal scan mode.
DIRECT TUNE
See Figure 19.
With Direct Tune in RACE mode, you can select and monitor
single channels.
 Press Direct Tune on the keypad to the right of the
LCD.
 Enter the desired seven-digit frequency, using the
numbers on the keypad. Seven digits must be entered.
The scanner will not tune until all dashes are filled.
 In RACE mode, the first digit entered must be the number
"4", or the entered frequency will not be accepted.
NOTE: If an incomplete or partial frequency, or one that
does not exist is entered, the radio will return to scan
mode after ten seconds.
 After a station is keyed there is a two-second delay.
The scanner will then switch to and monitor only
that frequency. The displayed frequency can then be
monitored exclusively, blocking all other transmissions
or added to the memory as a preset.
NOTE: To add a preset frequency, tune to the desired
frequency, select any numbered button on the keypad,
and hold for three seconds.
 To switch back to normal scan mode from single-channel
monitoring, press and release the Backspace/Clear
button.
