1.

Ventilation - Although your PHONO 1 Phono Stage generates

only nominal heat in use, be sure that the ventilation slots in the
top cover have 

at least

6” of unobstructed air space above them.

Do Not obstruct the bottom vent by operating the phono stager
on carpet or with the rubber feet removed.

2.

Water and Moisture - This product should not be used near

water. Do not expose this product to rain or moisture to prevent
fire or shock hazard.

3.

Heat - This product should be situated away from heat

sources such as radiators, heat registers, stoves, or other appli-
ances which produce heat.

4.

Power Sources - This product should be connected to an AC

power source of the proper rated voltage. The original shipping
containers will stipulate the AC voltage this unit can operate with
correctly.

5.

Cleaning - A regular dusting with a soft, non-abrasive cloth

will generally keep the finish of the faceplate and chassis looking
like new. At no time should you allow any liquid to come in con-
tact with the PHONO 1 Phono Stage; it may run into the elec-
tronic circuitry and cause damage which will not be covered
under your warranty.

6.

Servicing - Do not open this product. 

No user serviceable

parts inside.

Refer servicing to an authorized service technician.

7.
