Hidden Settings

To put the receiver in RSSI Display Mode,

the receiver must be off. Hold down the

the power button to turn the receiver on. The

receiver will turn on in RSSI Display Mode

A449

Note that the receiver will remain in this mode

until it is powered off. When powered back

on, the receiver will return to it’s normal home

screen, displaying the battery strength bars.

SETTINGS LOCK

To lock (or unlock) the settings, you must

rst be on the home screen. Push-and-

hold the left and right arrow buttons at the

same time. While holding the buttons, you

will see the following dashed-lines appear

one-by-one, then disappear one-by-one.

Keep holding the buttons until all three

lines disappear and the “PRESS MENU TO

LOCK” screen is displayed.

When the display shows “PRESS MENU TO

LOCK”, release the buttons. Then push the

Menu button to lock. The display will show

“LOCKED” (below) and then will return to the

home screen.

TURN-ON VOLUME

When the unit is powered on, or when the

channel is changed, the audio will be muted,

then rise to a set volume. This set volume

can be: (1) a specic volume level or (2) the

last volume used when the receiver was

powered off. This is called the “Turn-On

Volume” setting.

To access the Turn-On Volume setting, the

receiver must be off. Hold down the right

arrow button and while holding it, hold down

the power button to turn the receiver on. The

receiver will turn on and display “VOLUME AT

PWR ON”.

The default turn-on volume from the factory

is 8. This means every time the receiver

turns on, the audio will rise to volume level 8.

To change this to a different level, use the left

or right arrow buttons to adjust it. (Note that

this screen times-out in 20 seconds without

any button pushes). The highest turn-on

volume level is 15. The lowest setting (where

“0” would be) will restore the audio to the

last-used volume. Instead of “0”, the words

“LAST SETTING” will be displayed. This

means the next time the receiver is turned

on, the audio will rise to the volume setting

used when the receiver was turned off.

RSSI DISPLAY MODE

The receiver can be used as a portable RF

eld-strength meter for testing the amount

of signal received from a transmitter. In this

mode, the receiver will display a numeric value

between 000000 and 032764, representing

the level of RF eld strength received. This

numeric readout is displayed in place of the

battery strength bars on the home screen.

This is called the RSSI (Received Signal

Strength Indicator) Display Mode.

Note: To unlock the settings, perform Step

9 again.

SOFT AUDIO TURN ON

When the unit is powered on, or when the

channel is changed, the audio will be muted,

then rise slowly to the turn-on volume

setting. This feature allows the user time

to turn the volume down or remove the

earphones/headphones before the volume

level becomes uncomfortable. The rate of

the soft audio turn on is not adjustable.
