BASIC OPERATION
■ Monitor function
This function is used to listen to weak signals without disturb-
ing the squelch setting or to open the squelch manually even
when mute functions such as the tone squelch are in use.
➥Push the desired band’s [MONI] to toggle the monitor func-
tion ON and OFF.
•While duplex is ON for repeater operation, the transmitting fre-
quency can be monitored with [MONI].
Push [q MONI] to toggle the monitor function ON
and OFF.
■ Audio mute function
This function temporarily mutes the audio without disturbing
the volume setting.
q Push [FUNC] then [HMUTE] to mute audio sig-
nals.
•“ ” appears.
w Push [E CLR] (or any other key) to cancel the
function.
•“ ” disappears.
■ Transmitting
CAUTION: Transmitting without an antenna may
damage the transceiver.
To prevent interference, listen on the frequency before
transmitting by pushing [MONI] or [q MONI] on the HM-98
microphone.
q Select the desired band with the desired band’s [MAIN] or
[BAND] on the HM-98 microphone.
w Set the operating frequency.
•Select output power if desired.See the next section for details.
e Push and hold [PTT] to transmit.
•“TX” appears.
•The S/RF indicator shows the output power selection.
•The operating frequency, etc. is automatically programmed into a
scratch pad memory. See p. 40 for details.
•A one-touch PTT function is available. See p. 25 for details.
r Speak into the microphone using your normal voice level.
•DO NOT hold the microphone too close to your mouth or speak
too loudly.This may distort the signal.
t Release [PTT] to return to receive.
