2c. RF Time-Out

The RF Time-Out setting determines how long the transmitter continues to transmit with no audio present (30 minutes, 4 hours,

or Always On). Note that the RF Time-out delay and Screen Time-out delay are two independent events. After the RF time-out

period occurs (with no audio input and no front panel button presses), the T45 will go into “sleep mode” to conserve power.

During “sleep mode” the RF transmitter is completely shut off and the power switch light will fade from bright to dark to indicate

the unit is in sleep mode.

To change the RF Time-Out:

1. Press the Menu button. The display will show “AUDIO SETTINGS” in the selection box.

2. Press the “v” button to display “RF SETTINGS” in the selection box.

3. Press the “>” button to display “RF CHANNEL” in the selection box.

4. Press the “v” repeatedly until “RF TIME-OUT” is displayed in the selection box.

5. Press the “>” button to access the RF TIme-Out Setting. The currently selected time-out delay will be shown in the

selection box.

6. Press the “^” or “v” buttons to change the RF Time-Out to “30 MINUTES”, “4 HOURS”, or “ALWAYS ON”. Note that the

setting changes live, it does not need to be “selected” with another button. The time-out delay displayed in the selection

box is the one that is active.

7. When the desired time-out delay is selected, press the Menu button to exit the menu and return to the main info screen.

REMINDER: If the lock icon

is displayed on the default display, the menu screens are locked, and you will not

be able to make changes from the front panel. To unlock the menu screens, refer to “Lock/Unlock Settings” under

“Controls and Features”.

3. PREFERENCES

The Preferences Settings provide the ability to change the Display Mode, Channel Mode, Screen Time-Out, User-Entered

Transmitter Description, or Restore Factory Default Settings.

3a. Display Mode
