Marantz PMD690 用户手册

When recording for extended periods, or using this unit in

a fixed environment, it is recommended to supply power
to the unit via the included AC adaptor.

Note
• It is recommended to only use the Marantz Professional brand

AC adaptor (model DA600) for use with the PMD690.

The PMD690 can operate using 8 standard AA size

alkaline batteries.

First load the batteries into the battery holder and then
load the holder as shown in the following illustration.

Battery Replacement
When the battery alert indicator (

) appears steadily in

the display, replace all batteries with new ones. For the

complete description of the battery alert indiactor, please

refer to page 12.

Fresh alkaline batteries will provide 1-1/2 to 2-1/2 hours

of record or playback time (display backlight off)

depending on the type of batteries used.

Different brands of alkaline batteries provide very

different levels of performance in the PMD690.  For a list

of the best performing alkaline batteries please see the
Marantz Professional website at www.marantz.com.

Notes
• When recording, to avoid problems caused by loss of battery

power, it is recommended to always use new alkaline batteries.

• Use only AA size batteries for replacement.

• Be sure to insert the batteries with correct polarity (as

illustrated on the battery holder).

• Remove the batteries if the unit will not be used for an

extended period of time.

• Battery life may vary depending on the conditions under

which the unit is operated (environmental temperature,

humidity, speaker usage, etc.).

• If batteries leak, dispose of them immediately. Avoid touching

the leaking material or letting it come into contact with
clothing, etc. Clean the battery compartment thoroughly before
installing new batteries.

• For optimum life and accurate battery display, make sure the

battery ("bat") preset is set to "al".  See page 9 for more
information on the preset menu.

An optional Ni-Cad battery (model RB1100) is available

for use with the PMD690.
Refer to the following illustration to load the battery.

Battery Replacement
When the battery alert indicator (

) appears steadily in

the display, charge the battery or replace the rechargeable

battery with a fully charged one.

A fully charged battery should provide 1-1/2 to 2 hours of

record or playback time (backlight off).

Charging Battery
The optional Ni-Cad battery is charged only when:

• The AC adaptor is connected
• The Ni-Cad battery is loaded correctly in the battery

compartment

• The CHARGE slide switch is set to ON

• The power to the unit is off

While charging, the CHARGE LED will blink.

When the charge cycle is complete, the CHARGE LED will

stay steadily on.

Notes
• The battery will not charge when the power to the unit is on.

Charging Time
Approximately 3 hours.

Notes
• Make sure to fully charge the battery before first use.
• Battery life may vary depending on the conditions under

which the unit is operated (environmental temperature,
humidity, speaker usage, etc.).

• It is recommended to only use the Marantz Professional brand

AC adaptor (model DA600) for use with the PMD690.

• For optimum life and accurate battery display, make sure the

battery ("bat") preset is set to "nc".  See page 9 for more
information on the preset menu.

• When recording, to avoid problems caused by loss of battery

power, it is recommended to always use a fully charged
battery.

• Remove the battery if the unit will not be used for an extended

period of time.

• If the charge LED does not blink when charging should be

taking place, remove and then restore power.

• The battery power should be completely used before it is re-

charged because Ni-Cad type batteries have a memory effect
which will reduce the total power of the battery if it is only
partially used and re-charged.
