BASIC OPERATION
3
MDC 1200 system operation■
The MDC 1200 signaling system enhances your transceiv-
er’s capabilities. It allows PTT ID*, Emergency signaling, and
receiving Radio Check. Also, the dispatcher can stun and re-
vive transceivers on the system.
* When [PTT] is pushed and/or released, the transceiver transmits
your station ID.
Transmitting an Emergency CallD
The MDC 1200 system’s Emergency feature can be ac-
cessed using the [Emergency] key (p. 7). The transceiver will
send an Emergency MDC 1200 system command once, or
repeatedly for a programmed number of times until it receives
the acknowledgement signal.
The emergency call can be transmitted without a beep sound
depending on how the emergency function is programmed.
Ask your dealer for details.
Receiving an Emergency CallDWhen an emergency call is received;q
• Beeps sound.
• The calling station alias and “EMG EMG” are displayed alter-
nately.
w Turn power OFF, change the channel, push [PTT] for reply-
ing the call, etc. to stop the beep and display indication.
Receiving a Stun and ReviveD
The dispatcher can send MDC 1200 system signals that will
stun or revive your transceiver. If a Stun command is re-
ceived that matches your station ID, the transceiver will dis-
play “SORRY” (default) and you can not receive or transmit.
When a Revive command is received that matches your sta-
tion ID, normal operation is restored.

Caution■
Misuse of Lithium-ion batteries may result in the following
hazards: smoke, fire, or the battery may rupture. Misuse
can also cause damage to the battery or degradation of
battery performance.
RDANGER! Use and charge only specified Icom battery
packs with Icom radios or Icom charger. Only Icom battery
packs are tested and approved for use and charge with Icom
radios or Icom charger. Using third-party or counterfeit bat-
tery packs or charger may cause smoke, fire, or cause the
battery to burst.
Battery caution
RDANGER! DO NOT hammer or otherwise impact the bat-
tery. Do not use the battery if it has been severely impacted
or dropped, or if the battery has been subjected to heavy
pressure. Battery damage may not be visible on the outside
of the case. Even if the surface of the battery does not show
cracks or any other damage, the cells inside the battery may
rupture or catch fire.
RDANGER! NEVER use or leave battery packs in areas
with temperatures above +60˚C (+140˚F). High temperature
buildupinthebattery, suchascouldoccurnear firesorstoves,
inside a sun heated car, or in direct sunlight may cause the
battery to rupture or catch fire. Excessive temperatures may
also degrade battery performance or shorten battery life.
RDANGER! DO NOT expose the battery to rain, snow, sea-
water, or any other liquids. Never charge or use a wet battery.
If the battery gets wet, be sure to wipe it dry before using.
RDANGER! NEVER incinerate used battery packs since in-
ternal battery gas may cause them to rupture, or may cause
an explosion.
RDANGER! NEVER solder the battery terminals or NEVER
modify the battery pack. This may cause heat generation,
and the battery may rupture, emit smoke or catch fire.
RDANGER! Use the battery only with the transceiver for
which it is specified. Never use a battery with any other
equipment, or for any purpose that is not specified in this in-
struction manual.
RDANGER! If fluid from inside the battery gets in your eyes,
blindness can result. Rinse your eyes with clean water, with-
