lead to the NEGATIVE (-) terminal. If you need to extend the power cable use #14 AWG or
larger insulated, stranded copper wire. Connect the cable to the transceiver pigtail only after
connecting to the battery.
Warning!
Never apply AC power to the power cable of the transceiver, for more than 15 volts DC.
When replacing the fuse, use only a 15-A fast-blow type, Damage resulting from failure to
adhere to these precautions may not be covered by warranty.
Base Station Installation
Operation from the AC line requires a power supply capable of providing at least 12 A con-
tinuously at 13.8 V DC. We recommend using an external speaker, since the internal speaker
is mounted on the bottom of the transceiver. The FP-700 AC power supply/loudspeaker is
available from yourYaesu dealer to meet these needs. Use the DC power cable supplied with
the transceiver for making power connections, and connect the external speaker cable to the
speaker jack on the rear panel.
External Speakers
Using an external speaker with the FT-2400H lets you position the source of audio where it
is most convenient to overeóme back-ground noise in and around the car. The op-tional SP-7
External Speaker includes its own swivel-type mounting bracket, and is available from your
Yaesu dealer. Of course the older SP-3, SP-4 or SP-55 External Speakers may also be used.
Plugging in an external speaker disables the speaker in the transceiver.
Microphones
The MH-26Q8J handie microphone for the European versión B FT-2400H includes a but-ton
on the front for transmitting a 1750-Hz burst tone, to access repeaters that require it. The
MH-27A8J DTMF keypad microphone also includes a button on the front, which, when used
with a versión A FT-2400H, duplicates the D / MR, button on the front panel of the
transceiver.
Both microphone models include a PTT (Push-To-Talk) switch to actívate the transmitter,
and DWN and UP buttons for tuning and memory selection.
Operation
This chapter describes the transceiver functions in detail. After studying these descrip-tions,
keep the FT-2400H Operator's Quick Reference Card handy in case you need to re-fresh
your memory.
Preliminary Setup
Before operating the transceiver, recheck power supply and antenna connections, and
connect your microphone to the front panel jack. Never opérate the transceiver without a
proper antenna for the operating band. Also, please read the earlier Controls & Connectors
section, if you have not already, to familiarize yourself with the controls.
As mentioned before, references to altérnate button functions have "F/W —>" in front of the
button ñame to remind you to press the F/W button first momentarily, and then the other
button within five seconds (while "F" appears (in reverse) above the leftmost frequency digit
on the display). Don't hold the F/W button down, as that will give you a different result, and
don't press two buttons as the same time (except the PTT switch, when storing a sepárate
transmit frequency). When a button should be held down (as opposed to just pressed
momentarily) the instructions will say so.
Afive-second timer starts when you press f/h, and clears when you pressing a button to make
a new selection. If you don't make a selection in five seconds, the button functions return to
normal (white labels).
A button beeper provides useful audible feed-back when buttons are pressed, at a level deter-
mined by the volume control. Each button has a different beep pitch, and each function has a
unique beep combination. For example, when you press the LOW LOCK button, you will
hear a pair of low-, médium- or high-pitched beeps corre-sponding with the RF power level
selected. You can disable the beeper as described in the box on the next page, but we
recommend you keep it enabled while getting to know the controls.
Turning Power Off
To turn the transceiver off, you must press and hold the POWER button for V2-second.
Beeper Disabling
If you want to turn the beeper off(or back on), you can press F/W —> TONE-» F/W —>
TONE (each button twice, alternately). If you lock the controls (page 14) and have the
beeper enabled, pressing a button will sound a dif-ferent musical note for as long as it is
held.
If you have trouble getting the transceiver to work as described, see In Case of Problems on
page 34.
