Battery Operation

Charging the Battery Pack

Before use the battery pack should be charged using the pro-
vided AC Adapter.
*Be sure to pull the DC cable out of the AC adapter when
you charge the battery.
1.Plug the AC cable of the AC Adapter into an AC outlet.
The POWER lamp illuminates.
2.While pushing the battery pack down, slide it in the direc-
tion of the arrow to mount it on the AC Adapter. Charging
starts, and the CHARGE lamp blinks green. It changes to
light steadily when charging is completed.
3.When charging is completed, remove the battery pack by
sliding it in the opposite direction of the mounting direc-
tion.

Attaching the Battery Pack on the GY-

HD100

If the DC cable is connected to the GY-HD100, unplug the
cable.
1.Hold the battery pack with the connector side facing the
GY-HD100.
2.While pressing the battery pack against the GY-HD100,
slide it downward to attach it to the GY-HD100.

Detaching the Battery Pack from the GY-

HD100

Ensure that the POWER switch on the GY-HD100 is set to
OFF.
1.While sliding the battery pack lock release lever, slide the
battery pack upward to remove it.
CAUTION
Do not detach the battery pack while recording is taking
place.
MEMO
•Do not connect or disconnect the DC cable while operat-
ing with a battery pack.
The following symptoms may occur if the DC cable is
connected or disconnected while operating with a battery
pack.
•The power is cut off for a moment when the DC cable is
disconnected.
•Noise to the video and audio signals occurs. Audio sig-
nal are muted.
•When operation is continued with DC input after the bat-
tery pack capacity has been used up, set the POWER
switch to OFF after the DC power is applied. Then switch
ON again.
•If the GY-HD100 is left with the battery pack attached, a
small amount of power is consumed even if the POWER
switch on the GY-HD100 is set to OFF.
Remove the battery pack when the GY-HD100 is not
going to be used.

Remaining Battery Power Display

When the remaining battery power is nearly exhausted, the
following warnings will be generated.
Viewfinder screen or LCD monitor
When a Status screen is displayed (excluding the STATUS
2, 3 screen in the Camera mode)
•Alarm indication: LOW VOLTAGE displayed.
FRONT and BACK TALLY lamp on camera: Blinks
Monitoring loudspeaker and PHONES jack: Alarm sound
MEMO
After the remaining battery power warnings appear, the GY-
HD100 automatically stops operation if the battery power
operation is continued.

Battery Recharge Times

•When charged at temperatures between 20°C (68°F) and
25°C (77°F).
•When charging battery packs after a long storage period,
charging time will be longer than indicated above.
•When two battery packs are attached, they will be
recharged in the order that they are attached.

Operating Time with Battery Pack

When a fully charged battery pack is attached, the approxi-
mate continuous operating time is as follows
•Battery operating time may differ depending on the age of
the battery pack, charging conditions and the operating
environment, etc. Use the values in the table on the above
for approximate reference times.
•Operating time is reduced in areas with a cold environ-
ment.
•Operating time is reduced when the power zoom lens and
LCD are used frequently.

Precautions for the Battery Pack

•When the battery pack is not in use, it must be stored in a
cool, dry place.
Do not leave the battery pack in a place where it might be
subject to a high temperature (under direct sunlight in a
car, etc.), this could cause leakage of the fluid or shorten
service life.
•When the terminal section of the battery pack gets dirty, the
operating time will be shortened.
•If the operating time becomes greatly reduced even imme-
diately after recharging, the service life of the battery pack
is nearly finished.
Purchase a new battery pack.

Recharging

•Recharge the battery pack after completely discharging it.
Repeated recharging with residual charge remaining could
result in reduced battery capacity.
•If the battery capacity is reduced by repeating incomplete
recharging, or recharging without discharging, once dis-
charge the battery pack completely, then recharge it to
restore the battery capacity.
•If the battery pack is recharged with its internal temperature
raised immediately after use, recharging may not be per-
formed completely.
•Perform charging in an environment where the tempera-
ture is between 10°C (50°F) and 35°C (95°F). 20°C (68°F)
to 25°C (77°F) is the ideal temperature range for charging.
If the environment is too cold, charging may not complete.
