You can use DTCS (Digital Tone Code Squelch) instead of CTCSS. 17) 12 3 BASIC OPERATION ` Setting squelch level The squelch circuit mutes the received audio signal depending on the signal strength. q While pushing and holding [PTT] and [MONI], turn the transceiver's power ON to enter the squelch adjustment mode. w Push [S-Ring/C-Ring] to increase the squelch level (tight squelch) or [MONI] to decrease the squelch level (loose squelch). · Squelch level will be fixed after 1 sec. [S-Ring/ C-Ring] [PTT] [MONI] D Open the squelch · Pushing and holding [MONI] cancels the squelch function. You can receive any signals on a channel. · Push [MONI] to turn ON the tone squelch function again. ` Auto Scan function Auto scan function proceeds in sequence from lower channel to higher channel numbers. Scanning searches for signals automatically and makes it easier to locate new stations for contact or listening purposes. w Scan starts automatically. · TX/RX indicator LED blinks green slowly. · When receiving a signal, scan pauses until the signal disappears. 13 BASIC OPERATION 3 ` Setting the group code number D USING THE CTCSS TONE CODE The transceiver is equipped with 52 CTCSS tones. (See next page) CTCSS operation provides communication with silent standby since you will only receive calls from group members using the same CTCSS tone. You can assign a different tone to CH 1 to CH 15 independently. q While pushing and holding [PTT], [S-Ring/C-Ring], [MONI], turn [VOL] to turn the power ON. w Select the desired CH 1 to CH 15 that you want to assign the CTCSS tone frequency to. e Push and hold [S-Ring/C-Ring] until a beep (Pi) is emitted. r Push [PTT] the necessary number of times to choose the 10 digit of the desired code from the channel list. t Push [S-Ring/C-Ring]. · Confirmation beep is emitted. (See next page. ) y Push [PTT] the necessary number of times to choose the 1 digit of the desired code from the frequency list. i Turn the power OFF, and then ON again.

The [MONI] key cancels the squelch setting. This is useful to listen to weak signals that do not open the squelch. Talk Range The IC-F22SR is designed to maximize performance and improve transmission range in the field. [. . . ]
