245 MHz FM TRANSCEIVER
i3FGX
FOREWORD
Thank you for purchasing the IC-3FGX 245 MHz FM transceiver.
READ ALL INSTRUCTIONS carefully and completely before using
the transceiver.
SAVE THIS INSTRUCTION MANUAL–This instruction manual
contains important operating instructions for the transceiver.
IMPORTANT
R CAUTION! NEVER hold the transceiver so that the antenna 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 2 to 4 in. (5 to 10 cm) away from the lips and the
transceiver is vertical.
R CAUTION! NEVER operate the transceiver with a headset or
other audio accessories at high volume levels.
R CAUTION! NEVER short the terminals of the battery pack.
DO NOT push the PTT when not actually desiring to transmit.
AVOID using or placing the transceiver in direct sunlight or in areas
with temperatures below +14°F (–10°C) or above +122°F (+50°C).
DO NOT modify the transceiver for any reason.
KEEP the transceiver from the heavy rain, and Never immerse it in
the water. The transceiver construction is water resistant, not
water proof.
The use of non-Icom battery packs/chargers may impair transceiver
performance and invalidate the warranty.

Battery cautions
• CAUTION! NEVER short terminals of the battery pack (or charg-
ing terminals of the transceiver). Also, current may flow into
nearby metal objects such as a necklace, so be careful when placing battery packs (or the transceiver) in handbags, etc.
Simply carrying with or placing near metal objects such as a necklace, etc. causes shorting. This will damage not only the battery
pack, but also the transceiver.
• NEVER incinerate used battery packs. Internal battery gas may
cause an explosion.
• NEVER immerse the battery pack in water. If the battery pack be-
comes wet, be sure to wipe it dry BEFORE attaching it to the
transceiver.
• Clean the battery terminals to avoid rust or miss contact.
• Keep battery contacts clean. It’s a good idea to clean battery ter-
minals once a week.
If your battery pack seems to have no capacity even after being
charged, completely discharge it by leaving the power ON
overnight. Then, fully charge the battery pack again. If the battery
pack still does not retain a charge (or only very little charge), a new
battery pack must be purchased. (P. 9)

Battery charging
D Rapid charging with the BC-119+AD-94
The optional BC-119 provides rapid charging of optional battery
packs.
The following are additionally required:
• One AD-94.
• An AC adapter (may be supplied with the BC-119 depending on
version).
When using the BC-119 in a vehicle: If the charge indicator
flashes orange, the vehicle battery voltage is low and charging
may not be performed. Check the vehicle battery voltage in this
case. If the charge indicator flashes red, there may be a problem with the battery pack (or charger). Re-insert the battery
pack or contact your dealer.
