Shows a term description
When the mouse cursor is moved over a term which
is highlighted in yellow, the description of term is dis-
played.
The screen shots at the right column, correspond to
the operating instructions and procedures shows both
setting and operating example.
Shows the location of keys
When the cursor is moved over a term with a red un-
derline, a red circle appears around the appropriate
key(s) on the fi gure of HM-133V.
Example: When the cursor is moved over [CLR]
the description, a red circle appears around
the appropriate key(s).

POCKET BEEP AND TONE SQUELCH
Tone scan
By monitoring a signal that is being operated with the
pocket beep, tone or DTCS Squelch function turned
ON, you can determine the tone frequency or DTCS
code necessary to open the squelch.
q Set the channel to be checked for a tone frequency
or code.
w Push [TONE] several times to select the tone type
to be checked.
• One of the icons " ," " " or " " appear.
e Hold down [T-SCAN] (TONE) for 1 second to start
the tone scan.
• Rotate [DIAL] to change the scanning direction.
r When the CTCSS tone frequency or DTCS code is
detected, the squelch opens and the detected tone
frequency is temporarily programmed into the mem-
ory or Call channel.
• The scan pauses when a CTCSS tone frequency or
DTCS code is detected.
• The detected CTCSS tone frequency or DTCS code
is used for the tone encoder or decoder, depending
on the tone condition or type selected in step w.
- No icon : Cannot be used for operation.
