GENERAL PRECAUTIONS & SAFETY NOTES
1. DANGEROUS VOLTAGES EXIST WITHIN THE CHASSIS. DO NOT REMOVE
CHASSIS COVER UNTIL UNIT HAS BEEN SWITCHED OFF AND
UNPLUGGED FROM THE WALL OUTLET (POWER) AND ALL
COMPONENTS FOR 15 MINUTES. TUBES BECOME HOT IN USE, AND CAN
CAUSE INJURY. DO NOT EXPOSE CHASSIS TO MOISTURE. DO NOT PLUG
INTO AN AC SOURCE UNTIL ALL CONNECTIONS ARE COMPLETED AND
ALL COVERS ARE INSTALLED.
2. Complete all signal connections before connecting the AC cord to the wall outlet and
turning the unit on. Similarly, always turn the amplifier off and remove the AC power
cord before detaching cabling. Failure to observe this sequence can result in damage
to the amplifier, speakers or associated components.
3. At turn on, all volume controls should be full counter-clockwise. Allow one (1)
minute for warm up before disengaging mute and commencing playback. Note: Mute
is automatically engaged when switching on units equipped with the remote control
option.
4. For protection of your speakers and power amplifier, always engage “Mute” before
switching the power off or on. Note: Mute is automatically engaged when switching
on.
5. DO NOT OPERATE THE UNIT IF IT IS WET.
6. THE CHASSIS CONTAINS VACUUM TUBES. DANGEROUS VOLTAGES
EXIST WITHIN THIS CHASSIS. NEVER REMOVE THE COVER UNLESS THE
UNIT HAS BEEN SWITCHED OFF AND COMPLETELY DISCONNECTED
FOR AT LEAST 15 MINUTES. THE TOP COVER MUST ALWAYS BE LEFT
SECURELY IN PLACE.
7. Take care to install your preamplifier securely in a sturdy, well designed stand so that
it will not fall or tip over (this could cause serious, possibly fatal injury).
