ANTENNA TUNER OPERATION
D Using the Internal antenna tuner
1. Push
TUNER
to turn ON the internal antenna
tuner.
• The indicator on
TUNER
lights.
2. Match the antenna.
L To match the antenna, see “Manual tuning” or “PTT
Tuner start” below.
D Manual tuning
You can manually match the antenna before
transmitting for the rst time.
1. Hold down
TUNER
for 1 second to start manual
tuning.
• The indicator on
TUNER
blinks red.
L The tuning normally takes 2~3 seconds.
2. After matching, the indicator on
TUNER
lights
white, and the internal antenna tuner stays ON.
L If the tuner cannot tune, the indicator on
TUNER
goes out, and the tuning circuit is automatically
bypassed.
D PTT Tuner start
The tuner is always activated when [PTT] is pushed
after the frequency is changed (more than 1% from
the last-tuned frequency). This function matches the
antenna for the rst transmission on a new frequency.
L You can turn OFF this function in the “PTT Start” item on
the TUNER screen. (p. 8-5)
MENU
»
SET > Function > Tuner > PTT Start
TIP: If the tuner cannot match the antenna
Even if the tuner cannot match the antenna on the
rst attempt, it may succeed by repeating the tuning
several times.
The internal automatic antenna tuner automatically
matches the transceiver to the antenna within the
range of 16.7 ~ 150 Ω (SWR of less than 1:3).
After the tuner matches an antenna, the latching
relay combinations are memorized as a preset point
for each frequency. Therefore, when you change
the frequency, the latching relay combinations are
automatically preset to the memorized point.
L When you install a new antenna, or you want to
change the antenna settings, you can clear all of
the internal antenna tuner preset points with the
“<<Preset Memory Clear>>” item on the TUNER
set screen. (p. 8-5)
MENU
»
SET > Function > Tuner >
<<Preset Memory Clear>>
NOTE:
• If the SWR is higher than about 1.5:1, hold down
TUNER
for 1 second to start manual tuning.
• When the transceiver receives a strong physical shock,
the internal latching relays may be returned to an
unlatched condition. In that case, push
TUNER
to turn
OFF the tuner, then turn it ON again to reset all latching
relays.
