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.
