OPERATION

Basic Operation

The HK 3370 is simple to operate, and very simi-
lar to stereo receivers you may have used in the
past. This section will explain the use of several
features that may be new to you.

• Install the two supplied AAA batteries in the
remote as shown. Be certain to observe the (+)
and (–) polarity indicators shown in the bottom
of the battery compartment.

• When using the HK 3370 for the first time, it
will be necessary to press the

Main Power

but-

ton

on the front panel to turn the unit on.

This places the unit in a standby mode, as indi-
cated by the amber color of the

Power Indi-

cator

. Once the unit is in standby, you may

begin a listening session by pressing the

System

Power Control

on the front panel or the

Main Power On

button

on the remote. Note

that the

Power Indicator

will turn red, then

green. This will turn the unit on and return it to
the input source that was last used. The unit may
also be turned on from standby by pressing any
of the

Source Selector

buttons on the front

panel

8 9 ! # $ &

or remote

To turn the unit off at the end of a listening ses-
sion simply press the

System Power Control

on the front panel or the

Main Power Off

button

∫

on the remote. This places the unit in

the Standby mode, and the

Power Indicator

will turn amber to remind you that the unit is

ready for operation when a power command is
received from the remote.
Power to any equipment plugged into the rear
panel

Switched AC Outlet

will be shut off.

When the remote is used to turn the unit “off”, it
is actually placing the system in a standby mode,
as indicated by the amber color of the

Power

Indicator

When you will be away from home for an
extended period of time it is always a good idea
to completely turn the unit off using the front
panel

Main Power Switch

Note that due its EEPROM backup system the
HK3370 will retain information such as pro-
grammed presets for a virtually infinite time (see
”Memory Backup”, page 14).

• To dim the brightness of the front panel dis-
play, press the

Dimmer

button

on the

remote or on the front panel

The first press will dim the lights to half normal.
A second press will turn the display completely
off. Press the

Dimmer

button

˙^

again to

restore the display to normal brightness.

Source Selection

• To select a source at any time, press any of the

Source Selector

buttons on the remote

front panel

8 9 ! # $ &

• During a listening session you may wish to
adjust the

Bass

Treble

and

Balance



controls to suit your listening tastes.

• Adjust the volume to a comfortable level using
the front panel

Volume Control

or remote

Master Volume Up/Down

buttons. The vol-

ume level is displayed by the position of the

Volume Indicator

. Think of the

Volume

Control

knob

as the face of a clock, with the

Volume Indicator

indicating the hour. The

HK 3370 is playing at the minimum volume level
when the

Volume Indicator

points to 7

o’clock; when the

Volume Indicator

points

to 5 PM, the HK 3370 is playing at the maximum
volume level. It is important that you make sure
never to exceed this maximum volume level at
any time, in order to avoid possible damage to
your loudspeakers due to “clipping”, a type of
distortion that is not audible to the human ear
until it is severe enough to permanently damage
most loudspeakers. It is also possible, depending
upon the program material, for clipping to occur
at volumes below the maximum volume level.

• To temporarily silence all speaker outputs, press
the

Mute

button

®5

. This will cut the output

to all Pre and Sub Outs and to all speakers, but it
will not affect any recording or dubbing that may
be in progress. When the system is muted, the

MUTE

indicator will light in the

Main Infor-

mation Display

and the

Volume/Mute

indicator

will flash. Press the

Mute

button

®5

again to return to normal operation.

• For private listening, plug the 6,3 mm stereo
phone plug from a pair of stereo headphones
into the front panel

Headphone

jack

• One or two separate sets of speakers may be
connected to the HK 3370. To listen to one of the
speaker sets, press the

Speaker

button

on the front panel corresponding to the

desired speakers or press them both to listen to
both speakers pairs. The active speakers will be
indicated by a lit green LED in the

Speaker

Indicators

display. Both sets of speakers

may be turned off for private headphone listen-
ing.

IMPORTANT NOTE:

When two speaker pairs

are connected to the HK 3370RDS and are to be
used simultanously, the impedance of each
speaker must not be lower than 8 Ohms.

• To program the HK 3370 for automatic turn-
off, press the

Sleep

button on the front panel

(

or remote

. Each press of the button will

increase the time before shutdown in the follow-
ing sequence:

The sleep time will be displayed in the

Main

Information Display

and it will count

down until the time has elapsed.

When the programmed time has elapsed, the
unit will automatically turn off (to Standby
mode). Note that the front panel display will dim
to one-half brightness when the Sleep function is
programmed. To cancel the Sleep function, press
the

Sleep

button

(©

or simply hold it pressed

for some seconds until the Sleep indicator num-
bers disappear and the Main Information Display
shows the current source. Pressing any control
button while the Sleep control is activated will
momentarily return the Main Information Display
to full brightness for increased legibility without
interrupting the Sleep function.

Tuner Operation

The HK 3370’s tuner is capable of tuning AM, FM
and FM Stereo broadcast stations. Stations may
be tuned manually or automatically, or they may
be stored as favorite station presets and recalled
from a 30-position memory.

Station Selection

1. Press the

AM/FM

buttons on the front

panel or on the remote

to select the tuner as

an input.

2. Press these buttons again at any time to
switch between AM and FM.

3. To automatically search for the next higher- or
lower-frequency station that has an acceptable
signal hold the

Tuning

button
