1� BATTERY CHARGING
Charging the battery pack
NOTE: Prior to using the transceiver for the first
time, the battery pack must be fully charged for
optimum life and operation.
LTo charge the battery pack while the transceiver is
ON, set the following item to “ON” (default).
» SET > Function > Charging (Power ON)
To charge the battery pack that is attached to the
transceiver:
• Connect a power source with a USB cable.
(p. 1-2)
• Connect a DC power supply with the supplied
DC power cable. (p. 1-2)
To charge the battery pack that is not attached
the transceiver, use the optional rapid charger.

Battery information
DBattery life
After the charging is completed, the battery life
will be approximately 3 hours when:
• Operating mode: FM
• Power save setting: Auto (Short)
• Duty cycle: TX : RX : Standby = 1 : 1: 8
(based on operating style)
DBattery icon
Icon Battery status
The battery is being charged.
The battery has sufficient charge.
The battery is exhausted to some extent.
The battery is nearing exhaustion.
Blinking The battery is almost fully exhausted.
No icon
When a DC power supply (13.8 V DC) is
connected, the battery is not being charged
because:
• The battery is completely charged.
• “Charging (Power ON)” is set to “OFF.”
LWhen the transceiver’s display is OFF, the charging
indicator lights orange while charging.
NOTE: BE SURE to replace the battery pack
with a new one approximately five years after
manufacturing, even if it still holds a charge.
The material inside the battery cells will become
weak after a period of time, even with little
use. The estimated number of times you can
charge the pack is between 300 and 500. Even
when the pack appears to be fully charged, the
operating time of the transceiver may become
short when:
• Approximately five years have passed since the
pack was manufactured.
• The pack has been repeatedly charged.
TIP: Keep the battery terminals clean. It’s a
good idea to occasionally clean them.

Transceiver
DCharging with the supplied DC power cable
You can charge the battery pack with the supplied DC power cable.
LWhen connecting a DC power cable, the transceiver needs:
• DC 13.8 V (Capacity: At least 5 Amps)
• A power supply with an over current protective line, and low voltage fluctuation or ripple.
NOTE:
• Confirm that the transceiver is OFF before connecting the DC power cable.
• You cannot connect the optional cigarette lighter cable (CP-22 and CP-23L) to the IC-705’s [DC 13.8 V] jack.
• If the applied voltage from the connected power source decreases, the battery pack is not charged, and the
battery pack is used as a power source while transmitting.
In this case, you cannot transmit if the battery pack is exhausted.
DCharging with a USB cable
You can charge the battery pack with a USB cable.
NOTE:
• You may not be able to charge:
- Depending on your USB cable or power adapter.
- When using a USB hub, or connected to a low output USB port.
• Charging time may differ, depending on the USB port.
• To use a mobile device or a PC as an external power source, set the following item to “ON” (default).
» SET > Function > USB Power Input (Phone, Tablet, PC)
• The battery pack is used as a power source while transmitting, even when an external power source is connected.
Therefore, you cannot transmit if the battery pack is exhausted.

DCharging with the optional rapid charger
The optional BC-202IP2  rapidly
charges the battery pack.
LThe charging indicator lights orange while charging,
and lights green when charging is completed.
LWhen about 90% of the battery capacity is charged,
the BC-202IP2 stops charging and the charging
indicator lights green. Therefore, the battery life
will be a little shorter than when charging with the
transceiver.
Approximate charging time: 2 hours
Charging note
RDANGER! NEVER use a battery pack that is not
manufactured or approved by Icom.
• The BC-202IP2  can only charge

VOX function
SSB, AM, FM, and DV modes
The Voice-Operated Transmission (VOX)
function switches between transmit and receive
with your voice. This function enables hands-free
operation.
Push to turn the VOX function ON or OFF.
The VOX function is ON.
DAdjusting the VOX function
Before using the VOX function, adjust the
following items.
• VOX GAIN
• ANTI VOX
• DELAY
• VOICE DELAY
1. Hold down for 1 second.
2. Touch the item to adjust.
(Example: ANTI VOX)
3. Rotate to adjust the item.
LTouching VOICE DELAY selects “SHORT,”
“MID,” “LONG,” or “OFF.”
4. To close the VOX menu, push .
VOX GAIN (Default: 50%)
Adjusts the transmit/receive switching threshold
level to between 0% and 100% for VOX
operation. Higher values make the VOX function
more sensitive to your voice.
ANTI VOX (Default: 50%)
Adjusts the ANTI VOX level to between 0% and
100% to prevent unwanted VOX activation from
the speaker or other sounds. Higher values make
the VOX function less sensitive.
DELAY (Default: 0.2s)
Adjusts the DELAY to between 0 and 2.0
seconds. Set for a convenient interval for normal
pauses in a speech before returning to receive.
VOICE DELAY (Default: OFF)
Sets the VOICE DELAY to prevent cutting off
your voice when switching to transmit.
• Select “SHORT,” “MID,” “LONG,” or OFF.
