3. Connecting microphone and headphones

The TG-288T transmitter has a built-in microphone, one external microphone-level input (3.5 mm), and one auxiliary-level input (3.5 mm).

You can use the built-in microphone or an external microphone. When an external microphone is connected to the transmitter, the built-in microphone is automatically disabled. When the external microphone is disconnected, the built-in microphone will resume operation. The built-in microphone can only be used in one-way mode

⚠ Note
Ensure that the microphone or auxiliary device is connected to the correct input jack. The microphone will not function properly if connected to the Aux input jack.

The TG-288R receiver has a separate headphone output (3.5 mm) and auxiliary output (3.5 mm). Connect headphones to the 3.5 mm headphone output or connect a recorder to the Aux output to capture content. Ensure that the connectors are properly inserted into place.

7. Battery life and charging

  • When the battery icon is displayed at full capacity 🔋︎, the battery has sufficient power.
  • When the battery icon is displayed as empty and the empty battery icon is flashing, this indicates low battery level, at 5–10% battery. Replace with a new battery or, if possible, charge it immediately using a USB-certified travel charger (optional accessories) or an appropriate Linkx charging station
  • The charging current is set to 255 mA. For safety reasons, there is a safety timer that will terminate charging after 12 hours of continuous charging. A fully charged battery provides approximately 14 hours of continuous receiver operation and 12 hours of continuous transmitter operation. However, please note that actual battery life depends on user settings, usage patterns, environmental conditions, battery manufacturer, and other factors.
  • During charging, the battery icon appears and disappears on the LCD screen:
    empty battery.

⚠ Note
The transmitter or receiver will automatically shut down during charging. If you wish to use the system while charging, press the power button again to turn the system back on.

8. Battery replacement

Step 1 Open the battery compartment cover

Step 2 Replace with a new battery.
(Ensure that the battery compartment polarity is correct.)

Step 3 Close the battery compartment cover.

9. Restarting when the LCD display freezes

In the unlikely event that the guide system freezes and stops responding, you can try to force shutdown by removing the battery, then inserting the battery back in and restarting the guide system.

10. Q & A

  1. The 🔇︎ icon is displayed on the transmitter.
    Check whether the transmitter is muted.
  2. My receiver LCD display content is flashing
    This indicates that no transmission signal is being received. Ensure that the transmitter is turned on and the receiver is within normal reception range. Both the transmitter and receiver are operating on the same channel and at the same frequency.

⚠ Important
To ensure proper signal reception, position the transmitter and receiver at least 30 cm apart. Placing the system too close will cause immediate saturation of the transmitted signal to the receiver, the system will then collapse, and the receiver will mute.
