General Precautions

Power Source

Attach the CL-2500 SSP to an AC power source only of the type

and voltage described in these operating instructions or as marked

on the rear panel of the unit.

AC Cord Wall-End

The CL-2500 SSP is equipped with a polarized, 3-pin AC power

plug that will fit into the AC outlet only one way. If you are

unable to insert the plug fully into the outlet, do not defeat the

directional plug by breaking off its rounded ground pin.

Instead, use a three-hole female to two-prong male adapter ob-

tainable in any hardware or electronics store. Be sure to utilize

the adapter plug’s “ground ring,” and fasten it to the outlet’s

cover plate attachment screw.

The CL-2500 SSP is designed to be operated in a “grounded”

state; that is, connected by its three-wire, three-prong AC cord

to your household’s AC earth ground. Defeating this ground con-

nection may impact performance and possibly render the all-

metal unit more vulnerable to static discharge shock from the

user’s hand. If the unit’s connection to ground is defeated by

necessity, i.e., grounded outlets are not present in household,

requiring use of two-pin adapter or two-prong cord:

• TAKE CAUTION to discharge accumulated static from

hand/body to some other inert metal object prior to

touching the CL-2500 SSP faceplate controls, or use the

remote control as much as possible if strong static condi-

tions are present in your listening environment. Even unfelt

static discharges can affect the CL-2500 SSP’s internal

microprocessors.

• If you suspect that static may have discharged to the

faceplate, turn the CL-2500 SSP off, unplug its AC cord

from the rear of the player or outlet, and allow to remain

off and unplugged for one minute to completely clear and

discharge. Re-plug the AC cord and turn the unit back on.

Normal function should resume thereafter.

Non-Use Periods

When left unused for a long period of time, the unit should be

disconnected from household AC. It is recommended that the

CL-2500 SSP be plugged into a UL (or similar) compliant surge

and spike protection device, preferably of high quality with sepa-

rate isolated ground paths.

CAUTION: Do not entrust the CL-2500 SSP nor any system com-

ponents to protective devices when environmental conditions

or public utility problems exist or are suspected. Occasionally,

lightning, brownouts, and extreme spikes or surges can not only

overwhelm your protective device, but can override a system

component’s internal fusing and do serious damage. Use the

rear panel switch to turn off your equipment when you are not

present to monitor conditions. Please reference the conditions

stipulated in the limited warranty policy.

INTRODUCTION 3

Installation Conditions

Environment

The operating temperature range of the CL-2500 SSP is 41-

95°

F

(5-35° C). Operating humidity is 5% to 90% (no condensation).

Do not operate the unit when ambient temperatures and/or hu-

midity are outside of this range.

Condensation

Moisture may form on the display lens due to temperature or

humidity extremes, or as relates to following:

• Immediately after a heater has been turned on

• When the unit is moved from a cold environment into a

warm one

• If placed too close in proximity to a heat source such as a

radiator etc.

If moisture forms inside the unit, it may not operate properly. To

correct the problem, move the product away from the heat

source, turn the unit’s power on and allow approximately one

hour for the moisture to evaporate before operating the unit.

Placement

As the CL-2500 SSP is a critical processing component, it must

be mounted on a stable, non-resonant and vibration-free sur-

face and outside the dispersion paths and magnetic fields of your

loudspeakers. DO NOT place the CL-2500 SSP directly atop

any device that emits heat or vibration (i.e., transformers, ampli-

fiers), nor in the path of direct sunlight.

Allow adequate air circulation (4” minimum surround) to pre-

vent excess internal heat buildup. Keep the CL-2500 SSP apart

from FM or cable TV coaxial antenna leads to minimize recep-

tion interference.

Precautions

Make all connections to and disconnections from the CL-2500

SSP with AC Power disconnected and all system components

switched “OFF.”

Commence installation with the CL-2500 SSP’s AC cord discon-

nected and the unit removed from power, with all other system

components turned off, until all interconnects are installed.

Whenever the CL-2500 SSP is connected to AC power and the

rear panel switch is “ON,” it is indeed “live,” and in Standby

mode. Turning the Front Panel Power Switch ON or OFF toggles

the SSP between “ON” and “Standby.”

Maintenance

Clean the CL-2500 SSP faceplate, control buttons and chassis

only with a soft, lint-free cotton cloth (like a well-worn, oft-

washed T-shirt), lightly moistened with a mild detergent solu-

tion.

Do not use any abrasive pad, scouring powder nor solvent-con-

taining spray cleaners, (especially anything including alcohol

and benzine) on the player.
