6.4 Scan Function

Press the SCAN button to initiate channel scanning. The radio will scan through active channels and stop when a signal is detected. It will resume scanning after a short delay or when the signal disappears.

6.5 CTCSS/DCS (Tone Squelch)

CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digital Coded Squelch) are used to filter out unwanted conversations.

• Press the TSQ/M4 button to access CTCSS/DCS settings.
• Select the desired tone or code from the available options.

6.6 TOT (Time-Out Timer)

The Time-Out Timer limits the duration of a single transmission to prevent accidental long transmissions and channel hogging. If the transmission exceeds the set time, the radio will stop transmitting automatically.

6.7 RFG (RF Gain)

RF Gain adjusts the sensitivity of the receiver. Lowering the RF Gain can help reduce background noise from weak signals or distant stations, improving clarity for stronger, closer signals.
