SET MODES

D LCD contrast (CONT)

(default: Auto)

• Auto

: Sets the contrast to high. However, if the transceiver is 

exposed to high temperatures, it automatically sets the 
contrast to low.

• HI

: Sets the contrast to high.

• LO

: Sets the contrast to low.

D PTT lock (PTT LK)

Turns the PTT lock function ON or OFF.
To prevent accidental transmission, etc., the transceiver has 
a PTT lock function.

(default: OFF)

D Busy lockout (LK OUT)

Turns the busy lockout function ON and OFF.
This function inhibits transmission while receiving a signal or 
when the squelch is open.

(default: OFF)

D Time-out timer (TOT)

To prevent accidental prolonged transmission, etc., the trans-
ceiver has a time-out timer. This function cuts transmission 
OFF after 1–30 min. of continuous transmission. This timer 
can be cancelled.

(default: 5)

• OFF

: The time-out timer is turned OFF.

• 1 to 30

: The transmission is cut OFF after the set period 

elapses.

Approx. 10 seconds before the time-out timer is activated, 
the transceiver emits a beep tone as a warning.

BE CAREFUL! The transceiver will become hot when this 
time-out timer function is turned OFF or set to the long 
periods, and transmission is made for long periods.

D Squelch delay (SQL DL)

Sets the squelch delay between short and long. The delay 
prevents the squelch from repeatedly opening and closing 
while receiving the same signal.

(default: SHORt)

• SHORt

: Sets the squelch delay to short.

• LOnG

: Sets the squelch delay to long.
