SET MODES
8-6
DTMF speed
Set the rate at which DTMF memories send individual 
DTMF characters to accommodate your operating 
needs.  (Default: dtd. 1)
 • dtd. 1:   100 milliseconds interval: 5.0 cps rate 
 • dtd. 2:  200 milliseconds interval: 2.5 cps rate
 • dtd. 3:  300 milliseconds interval: 1.6 cps rate
 • dtd. 5:  500 milliseconds interval: 1.0 cps rate
  (cps=characters per second)
Dial assignment
Selects whether or not to use [VOL] as a channel 
selector, instead of [Y] and [Z]. When [VOL] functions 
as a channel selector, [Y] and [Z] function as volume 
controls. 
  (Default: tOP.VO)
Option [VOL] [Y]/[Z]
tOP.VO Volume control Channel selectors
tOP.di Channel selector Volume controls
Simple mode
Selects whether or not to inhibit the access to some 
functions in the Set mode.  (Default: SmP.OF)
 • SmP.OF:  All settings can be accessed.
 • SmP.On:  
 
Some functions cannot be accessed.
NOTE: 
When “SmP.On” is selected, only the 
following functions can be accessed in the Set mode.
 • Scan resume setting
 • Function key timer
 • LCD backlight
 • VOX gain
 • MIC gain
 • VOX delay
 • VOX time-out timer
 • DTMF TX key
LCD contrast
Selects the LCD contrast.  (Default: Lcd.At)
 • Lcd.LO:  Sets the contrast to low.
 • Lcd.At: 
 
Sets the contrast to high.  
However, if the transceiver is exposed to 
high temperatures, it automatically sets 
the contrast to low.
Power save
The Power Save function enables you to conserve 
battery life by selecting the duty cycle of the receiver. 
Select the ratio of the power save time to the standby 
time. To turn OFF the function, select “P–S.OF.”
  (Default: P–S.At)
 • P–S.OF:  Turns OFF the function.
 • P–S. 2:   Sets the duty cycle to 1:2. 
(ON: 0.1 second, OFF: 0.2 seconds)
 • P–S. 8:   Sets the duty cycle to 1:8. 
(ON: 0.1 second, OFF: 0.8 seconds)
 • P–S.16:   Sets the duty cycle to 1:16. 
(ON: 0.1 second, OFF: 1.6 seconds)
 • P–S.At:   Automatically sets the duty cycle. 
When no operation occurs and no signal 
is received for 5 seconds, the transceiver 
enters the Power Save mode, and sets 
“1:2” as the duty cycle, and after 60 
seconds, it sets “1:16” as the duty cycle.
Select speed
Selects whether or not to accelerate the turning speed 
when rotating [VOL] rapidly.  (Default: S–S. At)
 • S–S. m:   Turns OFF the tuning speed acceleration.
 • S–S. At:  The turning speed is automatically 
accelerated when rapidly rotating [VOL].
