USING YOUR FR-540

Turning the Transceiver On and Off (PWR)

Pressing the PWR button (1) for 2 seconds will activate the unit. The speaker will sound a beep tone to confirm the transceiver’s activation. In addition, the transceiver will perform a 1-second power-on self-test, whereby the LCD dis- play will show all functional items, including a test of the 2-digit channel display (88 ), plus a test of the 2-digit CTCSS channel code display. To turn the unit off, simply press and hold the power button for 2 seconds then release it.

Volume Level

Audio reception volume is controlled by the Up (▲) and the Down (▼) button. Momentarily pressing either button will increase or decrease the volume level. A bar graph on the right side of the display will show the volume level setting.

Call Button (8)

When the call button is pressed, the FR-540 will transmit a 3-second ringing sound to other transceiver’s tuned to the same channel. This feature can be used to signal other parties that voice communication is desired.

Low Battery Alert

When the batteries are in need of replacement or charging, the low battery

icon will appear on the LCD display and the transceiver will sound a 1-minute beep to alert the user.

Monitor Button (M)

You can monitor channel activity by pressing the Monitor (M) button (3). If pressed for more than 2 seconds, you can continuously monitor channel activity. Press again, and channel activity monitoring is disabled.
