Alkaline Battery Case Installation
The supplied
SBT-12
Battery Case allows operation of
the
FTA-750/FTA-550
using six “AA” size Alkaline
batteries.
When installing batteries, insert the (–) end first, then
press in the (+) end so the battery snaps into place. Al-
ways replace all six batteries at the same time, paying
attention to the polarity indicated inside the case.
The SBT-12 must not be used with re-
chargeable cells. The SBT-12 does not con-
tain the thermal and over-current protec-
tion circuits (provided in the “SBR” series of Lith-
ium-ion Battery Packs) required when utilizing Ni-
Cd and Ni-MH cells.
Low Battery Indication
As your battery discharges during use, the voltage
will gradually become lower. When the battery volt-
age reaches 6.0 Volts, the “
” icon will blink on
the LCD display indicating that the battery pack
must be recharged before further use.
Avoid recharging Lithium-ion batteries before the
“Low Battery” indicator is observed, as this can
degrade the charge capacity of your Lithium-ion
battery pack. YAESU recommends that you carry an
extra, fully-charged pack with you so you will not
lose communications capability due to a depleted
Lithium-ion battery.
You may insert the cable plug of the
SAD-11
into the
EXT DC
jack located on the right side
of the transceiver directly.
4. If the transceiver is inserted correctly, the RED indi-
cator on the
SBH-11
will glow. A fully-discharged
pack will be charged completely in 4 hours.
It takes 5 hours for full charge with the
SAD-
11
connected to the transceiver directly.
Important Notes:
The
SAD-11
is not designed to power the trans-
ceiver for operation (transmission).
Do not leave the charger connected to the trans-
ceiver for continuous periods in excess of 24 hours.
Long term overcharging can degrade the Lithium-
ion battery pack and significantly shorten its useful
life.
If using a charger other than the
SAD-11
,
SBH-11
,
or if using a battery pack other than the
SBR-12LI
,
follow the appropriate instructions provided with
the charger/battery. Contact your Dealer if you have
any doubts about the appropriateness of the particu-
lar charger or battery pack you intend to use.
