How to insert the batteries
Remove the cover of the remote control unit with a
screwdriver. After checking the polarity (
+/_) of two AA
batteries, insert the batteries, replace the cover and replace
the screws.
< Take care not to pinch cables with the battery case.
Battery Replacement
If the distance required between the remote control unit and
main unit decreases, the batteries are exhausted. In this case
replace the batteries with new ones.
Precautions concerning batteries
< Be sure to insert the batteries with correct positive “+” and
negative “
_” polarities.
< Use batteries of the same type. Never use different types of
batteries together.
< Rechargeable or non-rechargeable batteries can be used but
not mixed together. Refer to the precautions on their labels.
< When the remote control unit is not to be used for a long
time (more than a month), remove the batteries from the
remote control unit to prevent them from leaking. If they
leak, wipe away the liquid inside the battery compartment
and replace the batteries with new ones.
< Do not heat or disassemble batteries and never dispose of old
batteries by throwing them in a fire.
Protection circuits
In order to protect the output level to the tubes, this unit is
equipped with a protection circuit to detect overcurrents.
When an overcurrent is detected, the protection circuit will shut
off the output tube’s current and continue to do so until the
power is switched off.
Presumably, the main cause of a protection circuit activating is
when the speaker cord connected to the output port short
circuits. The protection circuit may also activate when it is
connected to a speaker with lower impedance than allowed,
resulting in a large input that creates an overcurrent.
When the protection circuit has activated, look at the output
port and the speaker it is connected to and remove the cause of
the overcurrent. Following this action, wait 5 minutes and then
turn the power back on. Should the protection circuit continue
to activate even after removing the cause of the overcurrent,
please contact your dealer or contact TEAC for service
instructions.
When a large signal is input while a protection circuit is
functioning, a very slight electrical noise from the current may be
heard. This is not cause for alarm. This is the circuit maintaining
its protection of the output tubes.
