ABOUT FM APPROVED
Versions of the IC-F70/F80 which display the “FM
APPROVED” symbol as at left on the serial number
seal, conform to intrinsically safe ratings of the
FMRC (Factory Mutual Research Corporation).
Intrinsically safe :
Class I, II, III, Division 1, Groups C, D, E, F, G
Nonincendive : Class I, Division 2, Groups A, B, C, D
Connected battery pack : BP-254FM
The repair and maintenance of an FM approved transceiver can only
be performed in an Factory Mutual approved repair facility. The FM
approval will be canceled if FM intrinsically safe radios are repaired
anywhere else except in an approved facility.

CAUTION! NEVER hold the transceiver so that the an-
tenna is very close to, or touching exposed parts of the body,
especially the face or eyes, while transmitting.The transceiver
will perform best if the microphone is 5 to 10 cm (2 to 4 in.)
away from the lips and the transceiver is vertical.
CAUTION! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels.
CAUTION! NEVER short the terminals of the battery
pack.
CAUTION! NEVER use non-Icom battery packs/char-
gers to prevent the loss of the transceiver’s good performance
and warranty.
DO NOT push PTT when not actually desiring to transmit.
DO NOT use or place the transceiver in direct sunlight or
in areas with temperatures below –30°C (–22°F) or above
+60°C (+140°F).
The basic operations, transmission and reception of the trans-
ceiver are guaranteed within the specified operating tempera-
ture range. However, the LCD display may not be operate
correctly, or show an indication in the case of long hours of
operation, or after being placed in extremely cold areas.
DO NOT modify the transceiver for any reason.
Optional unit installation should be done at authorized Icom
service center only.
BE CAREFUL! The IC-F70/F80 series transceivers
employ waterproof construction, which corresponds to IPX7
of the international standard IEC 60529 (2001), 1 m depth
for 30 minutes. However, once the transceiver has been
dropped, waterproofing cannot be guaranteed due to the fact
that the transceiver may be cracked, or the waterproof seal
damaged, etc.
Approved Icom optional equipment is designed for optimal
performance when used with an Icom transceiver. Icom is not
responsible for the destruction or damage to an Icom trans-
ceiver in the event the Icom transceiver is used with equip-
ment that is not manufactured or approved by Icom.

3BASIC OPERATION
DTransmitting notes
• Transmit inhibit function
The transceiver has several inhibit functions which restrict
transmission under the following conditions:
- The channel is in mute condition (‘Inaudible’ condition;
“”does not appear.)
- The channel is busy.
- Un-matched (or matched) CTCSS is received.
(Depending on the pre-setting.)
- Un-matched (or matched) NAC is received.*
(Depending on the pre-setting.)
- The selected channel is a ‘receive only’ channel.
*Digital mode operation only.
• Time-out timer
After continuous transmission for the pre-programmed time
period, the time-out timer is activated, causing the transceiver
to stop transmitting.
• Penalty timer
Once the time-out timer is activated, transmission is further
inhibited for a period determined by the penalty timer.
DTX code channel selection
If the transceiver has [TX Code CH Select] assigned to it,
the indication can be toggled between the operating channel
number (or name) and TX code channel number (or name).
When the TX code channel number (or name) is displayed,
[CH Up] or [CH Down] selects the TX code channel.
USING [TX CODE CH SELECT] KEY:
qPush [TX Code CH Select]—a TX code channel number
(or name) appears.
wPush [CH Up] or [CH Down] to select the desired TX code
channel.
ePush [Call] to transmit the selected TX code.
USING [TX CODE CH UP]/[TX CODE CH DOWN] KEY:
If the transceiver has a [TX Code CH Up] or [TX Code CH
Down] key assignment, the programmed TX code channel
can be selected directly when pushed.
