Q: The power indicator of my AIWA GBTUR-120MKII turntable is blinking instead of staying on

The blinking of the power indicator usually indicates a connection or power supply issue, rather than normal operation. On this turntable, the indicator should remain steadily lit once the device is powered on. Check in the following order: Power cord : Ensure that the cable is securely plugged into the wall outlet (at the back of the turntable). The device operates on 100V-240V AC, 50/60Hz. DC 5V adapter : Check that the power adapter provided with your turntable is properly connected to the DC 5V port of the turntable and that the USB cable is not damaged. ON/OFF switch & VOLUME : Turn the control to the power-on position. Blinking may occur if the contact is not properly established. If the indicator continues to blink after these checks, the adapter or the internal circuit of the turntable may be defective and require replacement.

Question 1

The screen only shows the time at startup and I cannot navigate between modes

Accepted Answer

This behavior is normal at startup. Here’s how to navigate correctly:

Use the ⏻/MODE button

The ⏻/MODE button serves two functions: turning the device ON/OFF AND switching between modes. Press this button several times (briefly) to switch from one mode to another.

The available modes on the BBTC-550 are:

bt - Bluetooth
AUX - Auxiliary input
rd - FM Radio
tAP - Cassette
Cd - CD
USB - USB stick

If only the time is displayed

The device may be in standby mode with the screen frozen. According to the manual, you can press and hold the ⏻/MODE button for 2 seconds to completely turn off the screen. A short press on this same button will reactivate the device and display the last used mode.

The LCD screen will then light up and indicate the current playback mode, allowing you to navigate normally between modes.

Question 2

How to activate the subwoofer mode on the AIWA AVD97 amplifier without a remote control?

Accepted Answer

To activate the subwoofer mode on the AIWA AVD97, you must first use the MANUAL SELECT button on the remote control, which will display "SUBW OFF" on the receiver's screen. This initial step cannot be bypassed without the remote control.

However, once the display shows "SUBW OFF", you can then use the front panel buttons to activate the subwoofer:

Within 4 seconds of the "SUBW OFF" display, press the TUNING (DOWN) button (M button) or turn the MULTI JOG selector to the left to display "SUBW ON"
The subwoofer mode is then activated

It is important to respect the 4-second window; beyond that, the display returns to normal and you must start over by pressing MANUAL SELECT on the remote control again.

The subwoofer output of the AIWA AVD97 receiver provides a voltage of 5.0 V. Make sure your powered subwoofer is properly connected to the SUB WOOFER 3 jack at the back of the unit before activating this function. If no subwoofer is connected, ensure to select "SUBW OFF".

The power indicator of my AIWA GBTUR-120MKII turntable is blinking instead of staying on

Accepted Answer

The blinking of the power indicator usually indicates a connection or power supply issue, rather than normal operation. On this turntable, the indicator should remain steadily lit once the device is powered on.

Check in the following order:

Power cord: Ensure that the cable is securely plugged into the wall outlet (at the back of the turntable). The device operates on 100V-240V AC, 50/60Hz.
DC 5V adapter: Check that the power adapter provided with your turntable is properly connected to the DC 5V port of the turntable and that the USB cable is not damaged.
ON/OFF switch & VOLUME: Turn the control to the power-on position. Blinking may occur if the contact is not properly established.

If the indicator continues to blink after these checks, the adapter or the internal circuit of the turntable may be defective and require replacement.

Question 4

How to automatically tune the channels?

Accepted Answer

To automatically tune the channels of your AIWA 70QS8093UHD:

First, make sure that your antenna is properly positioned for better signal reception
Press the Menu button on the remote control
Navigate to Settings (use the directional buttons)
Select Channels
Choose Automatic channel search
Select the broadcast type: Digital (DTT) or Cable depending on your reception source
Press OK to start the search

The automatic search then begins and scans all available frequencies. This process usually takes 5 to 10 minutes. During this time, your television displays in real-time the number of detected channels. Once the search is complete, a confirmation message appears and the found channels are automatically saved.

Practical tip: Upon first startup, a setup assistant appears. You can directly access the automatic channel search through this assistant by following the on-screen instructions. If you need to perform a search again later, simply follow the menu procedure described above. Wait for the search to complete before turning off the television or moving the antenna to avoid interrupting the process.

Question 5

Why is my AIWA ACD-24KBTU air conditioner blowing cold air when I have it set to heating mode?

Accepted Answer

If your AIWA ACD-24KBTU air conditioner is blowing cold air while in heating mode, this may be a normal function of the unit, especially during the automatic defrost cycle or the preheating phase. Here are the explanations and checks to perform:

Automatic defrost cycle: In heating mode, if the outdoor unit accumulates frost (which frequently happens in cold weather), the unit automatically activates a defrost cycle that typically lasts between 2 and 10 minutes. During this cycle, the indoor fan temporarily stops. This is a normal and necessary behavior to clear the frost from the condenser and restore optimal heating efficiency. Once the defrosting is complete, the air conditioner automatically resumes heating.

Initial preheating phase: When you activate heating mode for the first time, the indoor unit requires 2 to 5 minutes to preheat before it starts blowing truly hot air. During this period, the outgoing air may be lukewarm or slightly cold. This is normal and allows the system to stabilize its internal temperature.

Check the set temperature: Ensure that the desired temperature is set to a value higher than the current ambient temperature. If the room temperature is already equal to or higher than the setting, the air conditioner will not trigger the heating function since the threshold has been reached.

Check the selected mode: Verify on the unit's display or remote control that the HEAT mode symbol is correctly displayed. Press the MODE button until you see the heating indicator displayed properly.

Filter maintenance: Dirty filters significantly reduce heating efficiency. Regularly clean or replace the filters to ensure optimal air circulation and effective heating.

If after these checks the air conditioner still does not blow warm air after 10 minutes in heating mode (outside of the clearly displayed defrost cycle), contact a professional to check that the heat pump is functioning correctly.
