JVC GR-DX77 Instruction Manual

MasterPage: Start_Right

This camcorder’s 2-way power supply system lets you 
choose the most appropriate source of power. Do not use 
provided power supply units with other equipment.

Set the Power Switch to “OFF”.

Insert the terminal end 

a of the battery pack into the 

battery pack mount.

Firmly push the end 

b of the battery pack until it locks 

into place.

Connect the AC Adapter to the camcorder.

Plug the AC Adapter into an AC outlet. The POWER/

CHARGE lamp on the camcorder blinks to indicate 
charging has started.

When the POWER/CHARGE lamp goes out, charging 

is finished. Unplug the AC Adapter from the AC outlet. 
Disconnect the AC Adapter from the camcorder.

While sliding BATT. RELEASE, remove the battery pack. 

* Provided

● If the protective cap is attached to the battery pack, remove 

it first.

● During charging, the camcorder cannot be operated.

● Charging is not possible if the wrong type of battery is used.

● When charging the battery pack for the first time or after a 

long storage period, the POWER/CHARGE lamp may not 
light. In this case, remove the battery pack from the 
camcorder, then try charging again.

● If the battery operation time remains extremely short even 

after having been fully charged, the battery is worn out and 
needs to be replaced. Please purchase a new one.

● Since the AC Adapter processes electricity internally, it 

becomes warm during use. Be sure to use it only in well-
ventilated areas.

● Using the optional AA-V100 AC Power Adapter/Charger, 

you can charge the BN-V107U/V114U battery pack without 
the camcorder. However, it cannot be used as an AC 
Adapter.

● After 5 minutes has elapsed in Record-Standby mode with 

the cassette inserted, the camcorder will automatically turn 
off its power supplied from the AC adapter. In this case, the 
battery charge starts if the battery is attached to the 
camcorder.

Perform steps 

2 – 3 in “Charging The Battery Pack”.

* Provided

● Recording time is reduced significantly under the following 

conditions: 
• Zoom or Record-Standby mode is engaged repeatedly.
• The LCD monitor is used repeatedly.
• The playback mode is engaged repeatedly.
• The LED Light is used.

● Before extended use, it is recommended that you prepare 

enough battery packs to cover 3 times the planned 
shooting time.

Before detaching the power source, make sure that the 
camcorder’s power is turned off. Failure to do so can result in 
a camcorder malfunction.

Connect the AC Adapter to the camcorder as shown in 
the illustration.

The provided AC Adapter features automatic voltage 
selection in the AC range from 110 V to 240 V.

DANGER! Do not attempt to take the batteries apart, or 
expose them to flame or excessive heat, as it may cause 
a fire or explosion.
WARNING! Do not allow the battery or its terminals to 
come in contact with metals, as this can result in a short 
circuit and possibly start a fire.

The Benefits Of Lithium-Ion Batteries 
Lithium-ion battery packs are small but have a large 
power capacity. However, when one is exposed to cold 
temperatures (below 10°C/50°F), its usage time 
becomes shorter and it may cease to function. If this 
happens, place the battery pack in your pocket or other 
warm, protected place for a short time, then re-attach it to 
the camcorder.
