Expert Technology Studios LLC BST1 Manual De Usuario
11
This indicates the BST-1 is tuned to 5890 and is on PRESET channel 31. After 3 seconds, the
preset channel indication will change to the S meter function, that of the letter "S" followed by
a number from 1-9. This indicates relative signal strength, and this function will be explained in
detail later in this manual.
To single step through the Preset channels, momentarily press the top button. With each
momentary press of the button, the BST-1 will advance one preset channel that is in memory,
even if it is not currently active. The receiver audio is automatically decreased when channels
are changed and will remain decreased unless the channel is active ("S" meter indicates
something other than " S -")
4.4 CHANGING TUNING DIRECTION
To toggle the tuning direction up or down, hold the bottom button for about 1 second until you
hear one short "beep" tone, then release it. The Morse Code letter "U" (dit dit dah) for Up or
"D" (dah dit dit) for Down will be heard to indicate the new tuning direction. The direction
toggles each time the button is held for 1 Beep. The RDS will display PSET UP or PSET DN if you
are in PRESET MODE. If you are in TUNE mode, it will display TUNE UP or TUNE DN.
4.5 CHANGING MODES - TOGGLING BETWEEN TUNE AND PRESET MODES
To toggle between TUNE and PRESET modes, hold down the bottom button for about 3 seconds.
After the 1st second, you will hear the one "beep" that indicates direction change, but this time,
do not release when you hear this first beep and instead keep the bottom button depressed
until you hear two "beeps". Release the button and you will hear Morse code letter "T" for Tune
(if you were originally in PRESET mode). The tuning direction will remain from the previous
setting and the display will indicate TUNE UP or TUNE DN. Repeating this will toggle back to
PRESET mode with the Morse code “P” (dit dah dah dit) and the message PSET UP or PSET DN.
4.6 TUNE MODE
To scan while in the TUNE mode and find an active channel, momentarily press the bottom
button. Depending on tuning direction, it will scan up or down in 5 kHz steps from the start
frequency. The display will read out the tuned frequency as it scans and then stop on the first
active frequency. Because of the slow RDS update rate on some car FM receivers, it may not
show every 5 kHz frequency step, but each channel is being checked for activity.
When stopped on an active frequency, you may see a frequency display followed by two dashes
in place of the normal preset channel number. This indicates the current frequency is not in
preset memory.
For example:
9440 --
If the tuned frequency is already in Preset Memory, then the Preset Memory will be displayed as
in PRESET mode with the frequency and preset number associated with that frequency.
