Cleaningthe VideoHeads

Digital video camcorders record video signals onto the tape in very thin lines (as thin

as 1/8 the width of a hair). The following anomalies may appear if the video heads are

even slightly dirty.

* Mosaic or other blocky video artifacts (Fig. 1) or banding

(Fig. 2) appear on the picture during playback.

* Sound becomes distorted, or there is no sound during

playback.

* The message [HEADS DIRTY, USE CLEANING CASSETTE]

appears.

If such symptoms appear, clean the video heads with the

Canon DVM-CL Digital Video Head Cleaning Cassette* or a

commercially available dry cleaning cassette.

If the symptoms reappear shortly after cleaning, the

videocassette may be defective. Stop using it.

*Availability differs from areato area.

Video heads may become dirty under the following conditions:

* Using the camcorder in humid or hot places.

* Using cassettes with damaged or dirty tapes.

* Using the camcorder in dusty places.

* Using the video heads for a long time without cleaning them.

Fig. 2

_ NOTES

• Before you make important recordings, clean the video heads and make a test recording

in advance, We also recommend cleaning the video heads after use, before storing the

camcorder.

• Do not use wet type cleaning cassettes as this may damage the camcorder.

• Even after cleaning the video heads you may not be able to correctly play back tapes

that were recorded with dirty video heads,

Preparations

This chapter describes basic operations, such as navigating the

menus, and first time settings to help you learn more about your

camcorder.

Getting Started

Chargingthe BatteryPack

The camcorder can be powered with a

battery pack or directly using the

compact power adapter. Charge the

battery pack before use.

For approximate charging times and

recording/playback times with a full

battery pack, refer to the tables on

pages 59, 60.

Remove the battery

terminal cover before

attaching the battery

1 Plug the compact power adapter

into a power outlet.

Depending on the region of

purchase, a power cord for the

compact power adapter may have

been supplied as well. In that case,

connect the power cord to the

compact power adapter before

plugging it into the power outlet.

2 Connect the compact power

adapter to the camcorder's DC IN

terminal.

CHG (charge) indicator

DC IN terminal

3 Attach the battery pack to the

camcorder.

Press the battery pack lightly and

slide it up until it clicks.

4 Charging will start when the

switch is turned to _ (CHG).

The CHG (charge) indicator starts

flashing. The indicator goes out

when charging is completed.

1 Slide _BATI_ in the direction of the

arrow and hold it pressed down.

2 Slide the battery pack down and

then pull it out

0 II_IPORTANT

• We recommend charging the battery

pack in temperatures between 10 °C

and 30 °C (50 °F and 86 °F). Outside the

temperature range of 0 °C to 40 °C

(32 °F to 104 °F), charging will not start.

• Do not connect to the camcorder's DC

IN terminal or to the compact power

adapter any electrical equipment that is

not expressly recommended for use

with this camcorder.

• To prevent equipment breakdowns and

excessive heating, do not connect the

supplied compact power adapter to

voltage converters for overseas travels

or special power sources such as those

on aircraft and ships, DC-AC inverters,

etc.

• The battery pack will be charged only

when the camcorder is off.

• If remaining battery time is an issue, you

can power the camcorder using the

compact power adapter so the battery

pack will not be consumed.

• The CHG (charge) indicator also serves

as a rough estimate of the battery

charge status.

Two quick flashes at 1-second intervals:

Battery pack at least 50% charged. If

the indicator flashes quickly but not

exactly in this pattern, refer to

Troubleshooting (L_ 50).

One flash at 1-second intervals: Battery

pack less than 50% charged.

• Charged battery packs continue to

discharge naturally. Therefore, charge

them on the day of use, or the day

before, to ensure a full charge.

• We recommend that you prepare battery

packs 2 to 3 times longer than you think

you might need.

• USAand 0anada 0nly:The

Lithium ion/polymer battery

that powers the product is

recyclable. Please call

1-800-8-BA]q-ERY for

information on how to recycle this battery.

Installingthe BackupBattery Preparing theAccessories

The backup battery (CR1616 lithium

button battery) allows the camcorder to

retain the date, time (CCJ20) and other

camcorder settings while the power

source is disconnected. Connect a power

source to the camcorder when replacing

the backup battery to retain the settings.

1 Remove the battery pack, if one is

attached.

2 Open the backup battery cover.

3 Insert the backup battery with the

+ side facing out.

4 Close the cover.

The battery life of the backup battery is

about one year. _'t7 flashes in red when

the lithium button battery is not installed,

or when it needs to be replaced.

Fasten the grip belt.

Adjust the grip belt so that you can

reach the zoom lever with your index

finger, and the 'S{art/Stopl button with

your thumb.

I ToATTACHA SHOULDERSTRAP

Pass the ends of the optional

shoulder strap through the strap
