ADJUSTING SQUELCH

2.Turn on the TRC-237 by turning OFF/ VOLUME clockwise until you hear a click and a hissing sound.

3.Set OUT – CH9 – CH19 on top of the TRC-237 for the channel you want to tune:

•To quickly tune to Channel 9, set it to CH9. 9 flashes on the display.

•To quickly tune to Channel 19, set it to CH19. 19 flashes on the dis- play.

•To tune to any channel other than Channel 9 or Channel 19, set it to OUT. The previously selected channel number appears on the display.

Note: When you tune a channel, the channel’s number appears or flashes on the display for about 20 seconds then fades, to save battery power. To continuously display the channel number, press and hold DISPLAY on the side of the TRC-237.
