SERVICE MEASUREMENT

Bandpass

250Hz-15kHz

e.g. 7122 707 48001

LF Voltmeter

e.g. PM2534

DUT

RF Generator

e.g. PM5326

S/N and distortion meter

e.g. Sound Technology ST1700B

Tuner FW

Use a bandpass filter to eliminate hum (50Hz, 100Hz) and disturbance from the pilottone (19kHz, 38kHz).

S/N and distortion meter

e.g. Sound Technology ST1700B

Frame aerial

e.g. 7122 707 89001

Tuner AM (MW,LW)

To avoid atmospheric interference all AM-measurements have to be carried out in a Faraday«s cage.

Use a bandpass filter (or at least a high pass filter with 250kHz) to eliminate hum (50Hz, 100Hz).

system from the power supply completely,

remove the power plug from the wall

socket.

The type plate is located on the rear of the

set.

Inserting batteries into the

remote control

Insert two batteries type R06 or AA into the

remote control with the correct polarity as

indicated by the "+" and "-" symbols inside

the battery compartment.

CAUTION!

–Remove batteries if they are

exhausted or will not be used for a

long time.

–Do not use old and new or different

types of batteries in combination.

–Batteries contain chemical

substances, so they should be disposed

off properly.
