PREPARATIONS

Battery Operation (Cont’d)

•When you use an Anton Bauer battery, the remaining battery (capacity or time) can be displayed in the STA- TUS 1 screen of the LCD screen or viewfinder. Set BAT- TERY INFO. on the LCD/VF[3/4] menu screen to CAPA% or TIME to display the remaining battery. When using the IDX Endura battery, the remaining capacity (%) can be displayed. X See page 91.

Precautions for the Battery Opera- tion

•Do not detach the battery pack while recording is taking place.

•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 con- nected 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-HD250/GY-HD251 is left with the battery pack attached, a small amount of power is consumed even if the POWER switch on the GY-HD250/GY-HD251 is set to OFF.

Remove the battery pack when the GY-HD250/GY-HD251 is not going to be used.

Operating Time with Battery Pack

When a fully charged battery pack is attached, the approxi- mate continuous operating time is as follows

Battery Pack	Continuous Operating Time (at 25°C (77°F))
Dionic 90	Approx. 3.2 hours
(U model)
Endura-7	Approx. 2.5 hours
(E model)

•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.

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-HD250/GY-HD251 automatically stops operation if the battery power operation is continued.

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 tempera- ture raised immediately after use, recharging may not be performed 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.
