Using Your FR-541

Turning the Transceiver On and Off

Pressing the power 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 both the 2-digit channel display ( ) and the CTCSS channel display ( ). To turn the unit off, simply press and hold the power button for 2 seconds. The unit will confirm its shutdown with a single beep tone.

Volume Level

Audio reception volume is controlled by the Up (F10) and the Down (G9) button. Momentarily pressing either button will raise or lower the volume level in steps as

shown by 1Uo through 8Uo on the display. Pressing and holding either button will adjust rapidly.

Call Button (8)

When the call button is pressed, the call icon ( ) will appear on the display and the FR-541 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 tone to alert the user.
