Memo ry Mod e
This mode i s mainly for operatin g only on
specific frequ ency channels known in a dvance
(and programmed in to the memories). F or example, after storing the frequen cies of your local repeaters into memories , you can confine
operation to those channels by se lectin g the
memory mode. In this mod e, th e selecto r knob,
microphone b uttons and scanning function select sequentially from the stor ed memories . The
FT-2400H giv es you 31 memories, each of which
can store repeate r shift and direction, CTCSS
settings, a nd separate r eceive and transmit frequencies. There i s also α Me mory Tun e mode, in
which you can tune just like the dial mode, and
store the resulting retuned memory into the
same or another memory. This and ot her special
memory mode functions are describ ed later, but
you will wan t to keep these terms in mind.
You can tell at α glance which channelling
mode i s in by looking in the shaded memory b ox
a bove and to the left of the fre quency display. If
the box is empty, y ou are in the dial mode. Ify ou
see α number or an "L", "U' or "C" in the b ox, you
a re in the memory mode.
Th e ΜΒ button near the to p righ t corner of the
display (and the button on the front of the ΜΗ-
27A8 J microphone) toggles betwee n the dial a nd
memory mod es . While in t he memory mode,
y our previous dial mode selections are preserved. Also, wh en you switch from the dial to
the memory mode, the l ast-selected memory is
recalled .
Freq uency & Step Sel ection
You can se lect α new operatin g frequency
from either t h e dial mode or by retuning α
me mory. F or now, we suggest u sing the dial
mode. If you see α memory number in the memory box, press the MR button to switch to dial
mode. There are two w ays to se lect your operating frequency: by the selector kn ob, or with the
microphone button s. H owever, holding one of
the microphone buttons for more than 1/2-second starts th e scanner. This i s described l ater,
but if you've already starte d it, just press α
micro phone button again to sto p.
To select the MHz range in which you wish to
operate: first press the ΡάΖ butto n above the
se lector knob so that the kHz digi ts are
blanked, and then t urn the knob. To return to
normal tu ning and display, just w ait five seconds, or press MRi again to redisplay the kHz
digits, and t hen turn the sel ector knob.

Just recall the memory, press RPT as necessa ry

you may find this more straightforw ard when

reason this fails, you can perform α hard reset
by removing the top cover, and shorting ac ross
the split sol der pad on the circuit board exposed
on the inside of t he front p anel, j ust behind t he

Memory Backup
Normally, α lithium b attery inside the trans-
ceiver retains all settin gs and memories while
power is off o r disconnecte d. If the transceiver
looses its memories (but still operates properly), this b attery s hould be replaced.
The front p anel must be removed to gain
access to the battery, which is on the insid e of
the front panel, just behind the memory box on
the display. It should be replaced o nly be an
Yaesu-authorized technician to ensur e that i t is

Memo ry Cloning
All memory data stored in one transceiver

Installation o f Op tions
This section describes the installation procedures fo r the FRC-6 DTMF Pager and FTS- 17A
To ne Squelch Unit. These options are available
fr omy our Yaesu dealer.
The FRC-6 provides DTMF pagin g/se lcall feat u res u sing 3- di git DTMF stat ion ID codes.
Seven code me mories store your ID code plus
those of six frequently-called stations or groups .
Co ntro l is provided through the front panel of
the transceiver. See the "Operation" chapter for
operational details.
The FTS-17A inclu des α decoder for 38 ΕΙΑ.

0 Disconnect the D C power cabl e, and referring to Figure 1, re mo v e th e four screws
affixing the top co ver (two on either side),
and loose n the o ne on top from the bac k by
se veral turns. Li ft th e r ear edge of the cover
s lightly, then remove it.
Referring to Fi gure 2, note the accessory
mountin g locat ions. If in stallin g the FTS17Α, remove the paper from the doublesided adhesive pad.
0 Carefully align the pins with the white connectors on the board, and press the u nit(s)
in to pl ace. The FTS- 17A goes o ver the
smaller connector, and the FRC-6 o ver the
l arger one.
0 The factory adj usts the output tone l evels
(the small trimmers access ible through the
option boards) for the prop er deviation, so
they s hould require no further adj ustment.
C3 Replace the top co ver an d four screws remo ved in the first step, and remember to
tighten the sc r e w at the back of the top
