11 OTHER FUNCTIONS

DCooling fan control

Selects the cooling fan control condition from Auto and ON.

•Auto (AT) : The fan rotates during transmit and for 2 min. after transmission, or when the internal tem- perature of the transceiver exceeds the pre- set value until the temperature drops.

•ON (ON) : The fan continuously rotates.

DSquelch delay

Selects squelch delay from short and long to prevent re- peated opening and closing of the squelch during reception of the same signal.

•S : Short squelch delay.

•L : Long squelch delay.

DData transmission speed

Selects the data transmission speed for packet operation from 1200 bps and 9600 bps.

DMicrophone sensitivity

Selects the microphone sensitivity from high (H) and low (L) to suits your preference.

DSquelch attenuator

Turns the squelch attenuator function ON and OFF.

• ON	: The squelch attenuator activates when [SQL]
	control is set between 12 o’clock and fully
	clockwise position.
• OF	: The squelch attenuator does not function.
