BULLETIN # 3
MODEL: QR-666
SUBJECT: VFO STABILITY

TRIO-KENWOOD IS EXTREMELY PROUD OF THE RELIABILITY OF OUR COMMUNICATIONS 
GEAR. QUALITY CONTROL IS PERFORMED AT OUR TOKYO FACTORY AS WELL AS GARDENA 
CALIFORNIA FACILITY. 

WE HAVE FOUND THAT A SMALL PERCENTAGE OF THE QR-666 SWL RECEIVERS MAY HAVE
A SLIGHT CASE OF INSTABILITY IF CARELESSLY HANDLED IN SHIPPING.

HERE IS A SIMPLE CURE WE'VE FOUND TO ELIMINATE THE SYMPTOMS:

CHECK ALL THE SCREWS WHICH HOLD THE RF CIRCUIT BORAD (THE ONE WITH THE
SWITCH ATTACHED) CHECH THE TOP ABD BOTTON SCREWS (HOLDING SPACERS TO THE
CHASSIS). THE BOARD NUMBER IS X44-1110-00.

YOU'LL PROBABLY NEVER HAVE THIS PROBLEM, BUT .....
