Preparations

Power Supply

To use this camera recorder, you can attach a battery pack or connect an AC adapter to it.

( A Page 22 [Using a Battery Pack])

( A Page 22 [Using AC Power (DC IN Power)])

Note :

● Set the [POWER] switch to AOFFB before changing the power supply that operates this camera recorder.

Using AC Power (DC IN

Power)

�Charging the Built-In Battery

The date/time and time code data are stored using the builtin rechargeable battery.

When power is connected to the camera recorder, the built-in battery always gets charged. When the power is disconnected, the battery gradually discharges.

The battery will be totally discharged if left unused for 3 months and the date/time and time code data will be reset.

When this happens, set the [POWER] switch to AONB to display the [Initial Setting] screen, then set the date/time.

( A Page 26 [Setting the Clock (Initial Setting)])

Using a Battery Pack

Use an AC adapter (sold separately) to operate the camera recorder with AC power.

1

Connect the DC cable of the AC adapter to the [DC

INPUT] terminal of the camera recorder.

Check that the power of the camera recorder and the AC adapter is turned AOFFB and connect as shown in the diagram.

Continuous Operating Time

(At 25 f)

Approx. 3 h

Approx. 3 h

Memo :

● Actual operating times may differ depending on the age of the battery, charging condition, and operating environment.

● Operating time is shortened in cold environment.

● The operating time may shorten when power zoom is used, accessories are connected, or when the LCD monitor is frequently used.

Precautions for the Battery Operation

● Do not remove the battery when the [POWER] switch is

AONB.

● Do not insert or remove the DC cable when the battery is in use.

● Leaving the camera recorder unused with the battery inside will deplete the battery power even if you set the

[POWER] switch to AOFFB. Remove the battery if you are not using the camera recorder.

�Warnings by Lamps and Alarm Tones

● Warning status is indicated by tally lamps and alarm tones.

● The front and back tally lamps of the camera recorder blink.

● Alarm tone is output from the monitor speaker or

[PHONES] terminal.

Memo :

● If you continue to use the camera recorder while the power warning is displayed, the camera recorder will stop automatically when the battery or supplied voltage from the AC adapter becomes lower.

● Alarm tone is not output during recording.

Note :

● The remaining battery power and time are displayed as there are from the battery information. Accurate data may not be displayed according to the battery condition.

Replace the battery as soon as possible when the remaining battery power and time are low.

Precautions for Batteries

● Store the battery in a cool and dry place when not in use.

Do not expose the battery to high temperatures (such as in a car under direct sunlight). This will cause battery leakage and shorten the battery life.

● Operating time is shortened if the battery terminal is dirty.

● If the operating time shortens drastically even after charging, the battery may be reaching the end of its life.

Replace the battery with a new one.

Charging

● Use up the charge completely before you charge the battery. If the battery is not fully discharged before charging, the battery capacity may drop after repeated cycles.

● If the battery capacity drops due to repetitive shallow charging and discharging, it may be recovered by using up the charge completely and then fully charging the battery again.

● If you charge the battery immediately after using while the battery is still warm, it may not be fully charged.

● It is recommended that you charge the battery in an environment between 10 f and 35 f. The battery may not be fully charged or the charging time may be prolonged if charged under low temperatures (below 10 f).
