The appropriate squelch level depends on ambient noise conditions. You can program a different level for band A and B. Noise (Squelch opened) The current squelch level is incorrect. The current squelch level is correct.Audio No speaker output (Squelch closed) (Squelch opened) 1Press [F], [MONI]. ¥ The SQL meter indicates the current squelch level. The default is level 2; 4 segments are visible. 2Press [UP]/ [DWN] to select from 6 squelch levels. ¥ Select the level at which the background noise is just eliminated when no signal is present. ¥ The higher the level selected, the stronger the signals must be to receive. 3Press [OK] to complete the setting.

So, while using a repeater, you can manually check the strength of a signal that you receive directly from the other station. If the stationÕs signal is strong, both stations should move to a simplex frequency and free up the repeater. Press [REV] to switch the Reverse function ON (or OFF). ¥ ÒRÓ appears when the function is ON. Note: u If pressing [REV] places the transmit frequency outside the allowable range, then pressing the PTT switch causes an error beep to sound; transmission is inhibited. u If pressing [REV] places the receive frequency outside the allowable range, an error beep sounds and no reversal occurs. u Automatic Repeater Offset does not function while Reverse is ON. u You cannot switch Reverse ON or OFF while transmitting. AUTOMATIC SIMPLEX CHECK (ASC) While using a repeater, ASC periodically monitors the strength of a signal that you receive directly from the other station. If the stationÕs signal is strong enough to allow direct contact without a repeater, the ASC indicator on the display begins blinking. Press [REV] (1 s) to switch the function ON. ¥Ò Ó appears when the function is ON. ¥ While direct contact is possible, the ASC indicator blinks. ¥ To quit the function, press [REV] momentarily. Note: u Pressing the PTT switch causes the ASC indicator to quit blinking. u ASC does not function if your transmit and receive frequencies are the same (simplex operation). u ASC does not function while scanning. u Activating ASC while using Reverse switches Reverse OFF. u If you recall a memory channel or the Call channel that contains Reverse ON status, ASC is switched OFF. u ASC causes receive audio to be momentarily intermitted every 3 seconds.
