Scan; Busy Frequency Stop; Can Esume Ypes; Preferred Scan - Kenwood TK-90 Instruction Manual

Scan allows each of the channels that has a receive

activity. Channels must be added to the scanning
sequence in order to be scanned.
To activate Scan, press the key programmed as

Scan.

• The icon appears on the display.
• The channel add indicator (
on the display when the selected channel is added to
the scan sequence.
• If only one channel is added to the scan sequence or
has a frequency stored, pressing the Scan key causes
an error tone to sound and Scan does not operate.

BUSY FREQUENCY STOP

The transceiver will automatically pause on a channel
when a signal is detected. The transceiver will
remain on the busy channel for either a short time or
until the signal drops out, depending on which Scan
Resume type your dealer has set up (see below).
• The squelch must be adjusted to the noise threshold
point with no signals present for Busy Frequency Stop to
operate.
When the transceiver has paused on a channel, you
can transmit by pressing the microphone PTT switch.
Depending on your dealer settings, Scan may either
end when you transmit or continue to operate. If
Scan is set to continue even after transmitting, then it
will remain on the current channel for a
predetermined time before continuing. This time is
set so that if a signal re-appears on the channel, or if
you transmit again, Scan will remain on the current
channel until the signal either drops out or you stop
transmitting.
