How to Install Amplicomms TV3500

Connecting the Base

1. Connect the power adapter to the DC input socket on the base rear panel.

2. Connect the power adapter to an electrical outlet.

3. Connect the base to your audio source (TV/HiFi). Two methods are available:

• Using the supplied analog audio cable (3.5mm jack to RCA or 3.5mm).
• Using the supplied optical TOSLINK digital audio cable.
• If your TV/HiFi has no audio output socket, use the base microphone to pick up TV sound.

Ensure the AUX switch on the base is set to the correct input position (2 for Analog, 1 for Optical, 3 for Microphone).

Base Set Up

Charge the headset for approximately 2 hours and 30 minutes before first use. The headset LED will turn purple when fully charged. A full charge provides up to 6 hours of listening.

Advice: Always place the headset on its charging base after use to ensure it is ready.

Changing the Rubber Ear Buds

The headset comes with two sizes of ear buds (Small and Large). Gently pull off the existing ear buds and snap on the new ones.

Installing Batteries in the Remote Control

Insert two AAA batteries into the remote control, observing correct polarity.

Registering the Headset

The base and headset are paired by default. If re-pairing is needed:

1. Press and hold the Pair button on the base for 10 seconds until the power LED flashes.
2. Press and hold the microphone button on the headset for 10 seconds until its LED flashes.

The LEDs on both the base and headset will become steady when registration is successful.

Operation

Important: Hearing damage due to high volumes! This headset can produce volumes up to 125 dB. Avoid prolonged exposure to high volumes, especially for children.

1. Before use, set the volume on the remote control to a low value.
2. Turn on the audio source (TV/HiFi).
3. Turn on the headset by pressing the microphone button briefly.
4. Insert the ear buds into your ears, adjusting the angle for a comfortable fit and optimal sound quality.

Note: Low battery is indicated by 2 beeps every minute.

Using the Volume Keys

Use the [+] and [-] buttons on the remote control to adjust the volume.

Adjusting the Sound Level Balance

Use the [L] and [R] buttons on the remote control to adjust the sound balance between the left and right earpieces.

Select the Audio Profile (Equalizer)

Press the equalizer button on the remote control to cycle through 4 audio profiles: Flat, Bass Boost, Treble Boost, and Clarity.

Note: To reset to factory defaults, briefly press the pair button on the base.

Confirmation Tone

The TV3500 provides audible tones for various actions:

1. Two beeps: Volume reaches maximum or minimum.
2. Two beeps: Left/right sound level difference reaches maximum.
3. Long beep: Left and right sound levels are balanced.
4. Two beeps: EQ setting 'Flat' is selected.

Using Microphone Button

Pressing the microphone button switches between TV listening mode and transparency mode (indicated by a red headset light). The microphone hole on the headset picks up ambient sounds, allowing you to hear your surroundings.

Press the button again to return to TV listening mode (blue headset light).

Power Save Mode

The headset enters sleep mode after approximately 5 minutes of no signal to conserve power. Press the microphone button to wake it up.

To turn off the headset completely, press and hold the microphone button for 3 seconds.

Troubleshooting

No Sound

• Ensure the power adapter is securely connected to the base and outlet.
• Verify the headset is ON (red or blue LED steady).
• Charge the headset if the battery is low.
• Confirm the TV/HiFi is ON and the correct input source is selected on the base (AUX switch).
• Ensure the audio/video equipment is in playback mode.
• Adjust the headset volume to a suitable level.

Distortion

• Move the headset closer to the base.
• Adjust the audio source volume (TV/HiFi) if it is too low or too high.

SAR Information Statement

This wireless device is designed not to exceed emission limits for radiofrequency (RF) energy exposure set by the FCC. These limits are based on standards developed by independent scientific organizations.

The Specific Absorption Rate (SAR) limit set by the FCC is 1.6 W/kg. Tests are conducted at the highest certified power level.

The actual SAR level may be lower than the maximum as the phone uses only the power required to reach the network.

The highest SAR value for this model when tested for use at the ear is 0.025W/Kg, and when worn on the body.

FCC ID: 2AYP5TV3500.

Additional SAR information is available on the CTIA website (www.wow-com.com).
