OPERATION
This chapter describes thè various transceiver functions in detail.
After studying these descriptions, keep thè FT-2311R Operator's Quick
Reference Charts handy in case you need to refresh your memory.
Preliminary Operating Information
Before operating thè transceiver,
recheck power supply and antenna
connections. Never operate thè transceiver without an antenna.
Before proceeding, please read thè chapter on Controls & Connectors,
if you have not already, to familiarize yourself with thè functions of
thè controls. Note especially on page 5 thè description of thè terminol-
ogy used when referring to thè keys in this manual.
When thè function keys are pressed during reception, a single beep
will sound if thè command is accepted, or a doublé beep if thè command
is invalid. Except for certain special cases mentioned later, thè keys
are disabled during transmission.
If you have trouble getting thè transceiver to work as described, see
'In Case of Problems' on page 25.
Squelch
Setup
Before t u r n i n g on thè transceiver, set thè SQL control fully coun-
terclockwise. Now rotate thè VOL control out of thè click-stop and
adjust for comfortable volume on thè noise or received signal. The
BUSY/ON AIR indicator LEO should glow green. If a signal is present,
turn thè selector knob to select a frequency where only noise is heard.
Rotate thè SQL control clockwise just to thè point where thè noise is
silenced and thè LEO turns off. If thè SQL control is set further
clockwise, sensitivity to weak signals will be reduced. Now, whenever
-16-
a signal reaches thè receiver that is strong enough to open thè squelch,
thè indicator will glow green.
Note that while receiving, one or more bargraph segments may appear
along thè bottom of thè display, indicating signal strength on thè
receiving frequency. This indication is not affected by thè squelch
setting, so even squelched signals will have some indication. If you
notice more than one or two bargraph segments appearing while thè
squelch is stili closed, try reducing thè squelch control setting (if
you want to hear weak signals).
Transmitting
Procedure
Press thè LOW button to select low power output. When you wish to
transmit, wait until thè channel is clear (green LED off), and squeeze
thè PTT switch on thè microphone. During transmission thè BUSY/ON
AIR indicator will glow red, and thè bargraph will now show relative
transmitter power output. Release thè PTT switch to receive.
If more power is required, set thè LOW button to thè undepressed
position. However, whenever communication is possible with low power,
keep thè LOW button depresseti to minimize possible interference to
other stations.
If using a version B (in Europe), press thè T CALL button, either on
thè front panel or thè MH-14A8 microphone*, to transmit a 1750 Hz
Burst Tone to access repeaters that require it.
If version is modified for packet radio, thè T CALL button
on thè microphone is disabled - use thè button on thè front
panel to transmit thè burst tone.
