VIBRATE (VIB)
There may be occasions where you would want the HT446 to vibrate
on receipt of a valid call, or indeed set it up to vibrate in addition to an
audible alert. To enable the vibrate feature press "FCN" key four times.
VIB and OF (OFF) are displayed on the LCD. This indicates vibrate is
switched to off. To switch on press either the UP or DOWN channel
buttons then press ENTER to save your setting.
Voice scrambler (SCMB)
To avoid the potential eavesdropping of other users, HT446 offers a
built in voice scrambler. Press "FCN" five times, select ON or OF (OFF)
and then press "ENTER" to save the setting.
*Due to local regulation, in some countries the scrambler feature may
not be available, please check with your dealer prior to purchase.

SCAN press the "FCN" button six times. SCAN is displayed on the LCD.

momentarily press the scan button.
Channel Scan (1)

will stop on the channel. If you wish to skip active channels press
either the UP or DOWN keys to resume scanning.
Alternatively, press the PTT to reply. If you have programmed any
tone codes then the scan will look for those specific tones only.
CTCSS/DCS Scan (2)
If you selected CTCSS/DCS scan in scan setup then the HT446 will scan
the selected channel for any activity on all the CTCSS/DCS tones.
